Lanier Husky 106" Electric conversion

[karl k]

I decided a little while ago that I wanted a scale bush plane.

It had to have flaps, large wheels and be capable of STOL.
It would be nice if it was a model of a real plane as well.

I was also looking at getting a large scale plane.
Some reading was done and a few good candidates shined through.

The Sig Rascal 110 (110"ws), the Graupner Taxi (94.25"ws)and (on a suggestion from one of the local club members) the Lanier Husky (106"ws).

I ended up combining the two types of plane I was after and got the Lanier Husky 106 from Tower Hobbies. I see that they just dropped the price for the ARF.... Isn't that the way it goes :rolleyes:

The planned components are as follows

12s2p a123 batteries
CC 110HV speed control
Hitec HS645mg servos for the elevator halves and rudder
Hitec HS475HB servos for the ailerons and flaps
Axi 5345/14 brushless motor
22x12 prop
Spektrum AR7000 receiver
2s1p a123 receiver pack
6" dubro smooth air filled tires
2" foam tail wheel

When I received the plane and unpacked it, I was very pleased with the quality of the kit.

The covering was done quite nicely. The only thing I don't really like about the trim scheme of the plane is the excessively patriotic theme it has. Red, white and blue is one thing, but the stars on the bottom of the wing???

Those stars were removed by gently peeling them off and removing the adhesive residue with nail polish remover. The stripes may still disappear some time in the future.

I did some assembling before I picked up the servos as I just couldn't wait.

I hinged the flaps and ailerons, installed the stab and hinged the rudder and elevator halves.

The tail lined up perfectly. The hinging slots in the tail were faultless as well.

The wing is pretty good. One of the ailerons got put into the drill jig at the factory backwards and was drilled in the wrong location for the controls to be installed. That was an easy fix by simply drilling a new hole. I'll cover the old hole with some matching covering in the future.

The same aileron had a bend in it as well. The hinge slits in the wing matched this curve, though and I didn't notice when I installed the control surface. I will have to remove it, straighten it and re-hinge sometime.

Some pics from when I mocked the plane up when I first got it.

Horizontal stab hinged

I have my hand next to the stab to give and idea of size. Being 31" wide, it doesn't fit through a standard household door! It will fit turned, though....

Landing gear installed and the wings on. Sure pretty!

http://www3.telus.net/kethlerhvac/lanier_husky_build/0801070111.JPG

Here I have it assembled in my kitchen for a control test once the servos were installed.

Now I just need to wait on some parts.

Half my batteries will be arriving on Monday or Tuesday.

The speed controller is on order.

Waiting on prices from local suppliers for the motor.

Main wheels on order.

Will get some pics soon of the radio bay.

Let's hope for a maiden soon!!

Cool !!

I've been waiting to see one of these electrified.

To save some $$, why not look at the E-Flite Power 160?

I know you already ordered an ESC, but these have been working great for me at $94, you can't find a better value.

You could also go with one of their large outrunners, for $65 or so...

What plane to you have planned for this setup?
What is the projected wattage? thrust?

I ask, because I'm still not 100% sure which motor I'll use.

I would have gone with 14s a123's, but I wanted to leave my options open to use a different charging method.

I will be running 4 6s packs for a total capacity of 4600mAh and 12 cells in series.

Thanks for the info on those motors.

I am looking for 3000w minimum.
The Power 160 will do 2700w - The Axi 5345/14 will get pretty close to 4000w if I so desire.

Karl

I'm going to see a little over 3Kw @ about 460 oz. of thrust

[karl k]

I got 1/2 my cells!

This will at least allow me to power up my motor once I decide on one and receive it.

I'll post pictures of the packs I made in the next day or so.

Still a bunch left to do:

Glue windows into plane.
Assemble remaining battery packs.
Install larger main wheels.
Install speed controller, motor and prop
Mount cowling
Mount wing struts
Build the high voltage wiring harness c/w charging jacks and arming system

I would love to install a lighting system into this bird.
Has anyone used a nice system that is still available?
It would be amazing to have a nice, scale lighting system for it.

Thanks

Here's some quick shots of the packs as I began to disassemble them.

The security bit needed to open the packs without hassle.

http://www3.telus.net/kethlerhvac/lanier_husky_build/0801210011.JPG

The screws in the pack that the bit is required for. See the pin in the center? It keeps you from opening the pack with a regular torx bit.

Removed from the lower case.

http://www3.telus.net/kethlerhvac/lanier_husky_build/0801210014.JPG

I made the following packs from the cells I harvested from the DeWalt packs:
2x 6s1p packs to power the plane
2x 2s1p packs to power the receiver and servos
1x 4s1p pack for powering up to 25 size planes

All packs have balancing taps to hook up the LBA10 balancer.

Karl

[karl k]

BTW, Does anyone know where I can get heat shrink that will cover these packs?

I only know where to get high grade electrically rated versions. They are rated anywhere from 600v on up, so are quite heavy.

Thanks

Karl

[jrb]

Looking good Karl!

You might find some useful inof in my EQC thread: http://www.rcgroups.com/forums/showthread.php?t=752795 .

I got some heat shrink for my A123-10S packs from Batteries Plus -- I just soldered wires/leads onot the stock tabs.

[P-51C]

So, where did you get the bit to remove the screws?

Or did you drill out a torx bit?

[jrb]

The post will snap off fairly easily; I stuck a 3/32nds bit and hit the power on my poratble drill.

Then a standard T-10 works just fine.


Also, saved the DeWalts end caps and electric; could be used if balancing is required in the future.

[Smyk]

It is getting interesting

Indeed.

Great work karl k. Thats some real ingenuity to use those Dewalt battery's. Keep up the great work, and remember, we want VIDEO:D. (Well, of course finish the plane first. :p)

[karl k]

So, where did you get the bit to remove the screws?

Or did you drill out a torx bit?

I get the bit in a set from Princess Auto up here in Canada. I think Harbor Freight is your equivalent in the states.

Chuck it up in a cordless drill and away you go.

Speking of cordless drills.....

I made a dummy pack today to use the 6s packs in my 18v Milwaukee drill and sawzall. The 6s pack weighs quite a bit less than the 15 Ni-Cd's. :)

Gobs of power. I ran 65 1" holes through a 2x4 to see how much power I would have for how long. Did that in about 2 minutes. That's 30c, right? :rolleyes:

Karl

[karl k]

I did some "social networking" today and got 2 more packs for free!! :D

I'm trying something different with these ones. I will charge each cell individually, so they all start out exactly the same.

That should relieve some of the cell balancing problems I am having with the other packs.

Karl

[karl k]

I've come up with and interesting idea for an arming and charging system for this plane.

I'll try to make up a drawing and post it soon.

I've got some new pictures!!

One of the batteries that I got for free had some miscellaneous gunk on them.
I don't think it would be from inside the packs as these don't really have anything like battery acid inside them.

These packs were used, but wouldn't charge using the factory charger.
Maybe something got in while they were being used on the job site.

They don't look out of place at all. In fact, they could stand to be a little larger. Scaled 1/4, 31" Alaska bush wheels would be 7-3/4". That would look very sharp!!

Does anyone know of a good scale lighting kit for a model of this size?

Even if I just get the controller for the lights. I would like the proper strobes and some really bright landing lights if possible.

Power supply would not be an issue, I'll run another battery pack to power the lights.

Still to me obtained:

Motor (ordered)
Prop (ordered)
Deans connectors for wiring harness (ordered)
Heat shrink for batteries (ordered)

Still to be done to plane:
Re-hinge aileron
Glue windows in
Mount motor
Install cowl
Make cooling holes in airframe
Mount batteries
Set CG

It's getting closer. I can taste it!! :p

Does anyone see a problem with wiring the plane in this manner?

http://www3.telus.net/kethlerhvac/lanier_husky_build/husky%20wiring%20diagram.jpg

I would like to just have one shunt to disarm the plane. I am worried that running both chargers at the same time through the charging jacks could cause the plane to be live while charging.

Am I going to have to go with a series shunt as well as a shunt to disconnect one incoming line of power to the ESC as well?

Will my 2 chargers running off of the same 12v source have problems charging if they have the ESC connected between the + output of one charger and the - of the other?

Should I just play it safe?

[karl k]

I got my Axi 5345/14 today. It came in a long box along with a 22x10 Xoar prop.

Can anyone suggest a motor mount for the big Axi?

My heat shrink cam as well, so I have been covering my packs. They look much more professional than being covered with electrical tape.

How they will be arranged in the plane.

http://www3.telus.net/kethlerhvac/lanier_husky_build/0802050019.JPG

This will give me some room to slide the batteries fore and aft to end up with a proper CG.

The batteries weigh 17oz/ea x 4 = 68oz
The motor weighs 895grams = 31.5oz
The CC 110HV controller weighs 5.3 oz

Total power system weight = 104.8oz = 6.55lbs

A dry 45cc gasser motor w/muffler weighs anywhere from 4.5-5lbs.
That doesn't include the throttle servo, fuel tank and fuel.

It looks like I'll be close to the mark as far as weight goes.
She'll have plenty of power as well.

Karl

[preditor4u]

I would use the other adapter with the kit and put the stationary side of the motor to the rear. I am currently building a 1/3 scale RV-4 using the same motor. Hobby Lobby also sells a nice mount that will work with these motors. I am using one in my Taxi 2400 that I used an Axi 5330 with. Works great. Let me know if you need some pics.

FWIW

[karl k]

Pics are always awesome. Please post them if you can.

If you want, you can PM me and I'll give you my e-mail address.

Karl

[jrb]

Karl,

It depends on how you intend to mount the motor.

Using the adapter you shown mean you must hold the motor vai a plate that fits between the motor and prop (front mount).

Rather than using the aft mount as shown in my EQC photo.

To do like my Cub you need the RMS from AXI (Radial Mount System); it come with the Himaxx & E-Fliter motors. This is probably a btter choice for you too.

Sometimes you need to use the front mount; like with the VariProp on my Mustang: http://www.rcgroups.com/links/index.php?id=4788 .

I've put some photos here than might be helpful:

[preditor4u]

I will post some pics tonight.

[karl k]

jrb,

What size Axi did you put into that Mustang?

Edit:

I see that it is a 4130.

Axi does not offer an x-mount for the 53xx series of motors that I can tell.

If I had one, I would have an easy job. I had the mounting all worked out in my head using an x-mount.

Karl

[jrb]

4130/20

[karl k]

Edited my last post too late. :o

Karl

[jrb]

Maybe you could use one frome E-Flite or HiMaxx?

The AXI 4130, E-Flite 46 BL & 60 BL & HiMaxx 35mm have the same bolt pattern on the motor.

I'd guess the HiMaxx 63 (Like on my EQC) which seems to fit the E-Flite 110 & 160 BLs would woork with you AXI.

Do you have the specs somewhere?

Karl

I don't have all of that info; just some for the 4160.

My EQC's cowl is buttoned up, so I can't measure it.

One of our LHS usually has all 3 mfgs; do you have a shop near you?

You might get some info with a specific posting here, or an e-mail to them.

Don't unbutton the cowl for me. The mount will be a different size anyways.

I have posted elsewhere in RC Groups to find the E-Flite Power 160 info.

That is a nice, cheap, light route to go.

I found that the Power 160 x-mount and hardware will work perfectly for the motor I have.

I've asked for it to be ordered to my LHS. I'll get the motor mounted when it arrives.

Karl

[karl k]

Sorry I haven't updated lately.

I've had my wisdom teeth out and have been shipped out of town to work on a ski jump for the last week.

The speed controller is in, I just need to pick it up.
I need to call my LHS and see if my motor mount arrived.

That's about all I'm waiting for to be able to complete this thing.

I won't be able to fly it for the next while anyways.
Our wonderful municipal parks board rented out the field we use to a movie production company. The field is now closed until the 26th.

It really wouldn't be so bad if they didn't put a big metal tree in the middle of our runway.

Oh, well. Pylon racing it is....

Karl

[karl k]

It's alive and kicking!!!

I picked up the speed controller and motor mount today.
Got it installed and test run.

HOLY SMOKES!! This thing moves a lot of air.

I am having the odd speed controller error.
Does anyone else run an Axi 5345 with a CC HV110 ESC? What setting have you used?

I will post pics and power readings in the next day or so.

Karl

[karl k]

So, here's the latest pictures.

The 6mm bullet connectors for the motor soldered on. The female ones on the ESC were a little tricky because this speed controller uses #10 wire. It was a little snug to get into the connector.

Completed wiring harness. Those interested in a diagram should be able to follow the wires. It varies from the diagram I posted earlier in that it has an arming plug in series with one of the power wires of the ESC as well as the arming plug (series shunt) shown in the original diagram. had to do this for safety when charging. I did not want any chance of the ESC being powered while charging.

Well, I got back from working at the Olympic venues at Whistler.

http://www3.telus.net/kethlerhvac/lanier_husky_build/0803010001.JPG

I got some work done Friday night. The Deans connectors are mounted to the outside of the plane, the windows are in, the aileron that was giving me problems has been re-hinged and I've got my CG where I want it.

Here's some close-ups of the Deans connectors for those who asked. Don't be too hard on me for my cutting out the holes for the connectors. I'm not the greatest with an Xacto blade. :rolleyes:

I've got the arming plugs on a sort of leash to keep them from getting lost. (not shown in pics) I'm not terribly happy with the way that is right now. Looking for something to use that is ultra flexible and strong.
Will update with what I find for that purpose.

Well, the batteries are all charged and ready to go. Just the heavy duty wire to adapt from the Deans connector on my 2s receiver pack to the receiver switch needs to be installed. I need to pick that up from a buddy who is making that for me.

Anyone see anything that I may have forgotten? I don't think I'm forgetting anything. It'll become apparent whether or not anything was forgotten when it takes to the skies.

Karl

[jrb]

Very nice Karl!

Can you show us what you did to hold the Deans in the fuselage?

[karl k]

Just a hole in the side with epoxy.

The wire that heads to the positive terminal rests against a piece of plywood that is at 90 deg to the fuse side. I have extra long heat shrink on the wires, so I put a drop of CA there to ensure that it would not move.

Karl

[rpage53]

Deans are very hard to plug and unplug, so an unsupported mount causes a lot of stress. You may need to add an internal brace. Sermos (or Anderson Power Poles) are a lot easier to use for this purpose. Sorry I didn't suggest this earlier.

Rick.

[karl k]

What is the current rating of the Anderson connectors?

I'm looking at 110A peaks through this system.

Maiden today.

Took off at half throttle in about 2 plane lengths. Took one click of up trim and 2 of left aileron.

She's a real floater, even at 27oz/sq.ft wing loading.

Gobs of power. Even knife edges nice! Just a breath of rudder needed.

Went good, but our temporary field has a large dip in it which caused a nose over.

No damage.

Some witnesses took video. I'll try and get it and get it posted.

APP contacts are based on the size of the wire, so if the wire can handle it so can the connectors. The so-called 45A connectors are similar to Deans Ultra for up to 10 guage wire. They make a Deans plug with Sermos for arming.

If your Deans are loose enough, it doesn't matter. A little SuperLube can make them easier to plug.

Another flight today.

A lot nicer on the landing this time. Very gentle landing with minimal roll out.

Flew 6 minutes and looked to land. Total flight ended up being 8 minutes.

Put 2250mAh back into the packs.

Should have no problems with 10-12 minute flight timer.

No problems with the Deans connectors fitting well.

Others have used the same arming system as I have on their planes without issue, so I'm not worried. I have watched them get plugged and unplugged numerous times.

[AmpAce]

Karl,

You might want to check your motor mounts after flying a bit. Those long stand-off bolts may allow a bit of movement and torque twisting of the motor. Just be sure everything is staying tight and not moving around any. Better yet, you might want to build a motor pedestal, or use a section of round plastic pipe, as shown in post #34. This makes a much stiffer and better supported motor mount system.

It would be too bad, if that monster motor came loose and chewed up the front of that beautiful Husky.

Great job of putting it together, by the way! Your pic's and posts are great!

Happy Flying!

AmpAce

[karl k]

I put 3 more flights on her tonight.

10 minute flights require 3050 mAh and 22-24 minutes to charge at 8.75A

AmpAce: I am going to sleeve some 3/4 or 1" dowel from the firewall as far forward as I can on the mounting bolts. That should stiffen it up quite a bit. It is quite sturdy as is.

I bought 2 new deeps cycle batteries today so that I can charge the packs as fast as I want. As I mentioned, the recharge times are quite short. I don't think I would be able to get the battery packs out of the plane and new ones installed in 20 minutes as they are very awkward to remove.

All in all, a good evening.

Karl

[karl k]

6 more flights this evening.

I do have pictures and video on the way.

I did discover that the deep cycle batteries are only good for 4 charges of this plane. I measured 37 amps draw from a 12v Pb into the 2 chargers. No wonder it uses up the capacity so fast!!

I hope to increase the efficiency of the charges by using the zip charge method.

Pics to follow. Hopefully later tonight.

Karl

[karl k]

After 6 flights, I put 350mAh back into the receiver pack out of 2300. I think it should be no problem to get a day of flying with this plane and not worry about the receiver pack :)

Here are some photos from the field today.

I forgot to mention:

There was a fellow flier at the field today with a laptop and the software for measuring the speed of an aircraft by the doppler effect.

Mine clocked in at just over 140 kph (90mph)!!!

Now I really need to get a wattmeter on this thing so I know exactly what I'm drawing.

Karl

[karl k]

There's a video of the Husky up!!

Thanks again Mike.

http://www.youtube.com/watch?v=VNGGoTLdhlQ

During this video, we were trying to get a good reading for the speed with the doppler software, hence the high speed passes. It may have been a little fun as well. :p

As you can see, it lands in a fairly small space for the size of plane it is. I've got 560 feet from the dip in the ground that you really want to avoid on landing to the tall trees to the right in the video. Off to the left, there are trees as well, but not as tall. They do affect the approach angle, though.

Once again, I'm very happy with the way this model flies.

I've made a few changes that I should have made before, but I wanted to get a few flights out of the way so I didn't do all the detail work, then crash on the maiden.

I finally got the cooling hole cut out for the air to exit the fuse. I didn't have any heating issues, so I wasn't worried about it earlier. It has still been fairly cool here and I may run into problems come summertime. I put it off because it wasn't as easy as I had hoped. The openings that would have been created if I just cut the covering and ironed it over into the existing openings would have been about 2.5 feet long!! I ended up putting another cross member in the fuse so that I had something to iron down onto.

http://www3.telus.net/kethlerhvac/lanier_husky_build/0803090074.JPG

I got my data logging setup installed as well. I placed the Eagle Tree micro power logger securely on the dashboard.

http://www3.telus.net/kethlerhvac/lanier_husky_build/0803090078.JPG

I installed the Power Panel on the top of the dash so that it can be read from outside the plane. This will act as a gas gauge ant tell me how many mAh I have removed from my batteries as well as keep track of voltage, current and motor rpm.

http://www3.telus.net/kethlerhvac/lanier_husky_build/0803090079.JPG

Here are the wires to measure the motor rpm. I had to extend them in order to cover the distance needed to reach the motor leads.

http://www3.telus.net/kethlerhvac/lanier_husky_build/0803090080.JPG

I also have an idea for a motor mount that will suit this plane perfectly. I will have to talk with one of the local club members who does metal cutting and bending to see how much it would cost.

Karl

[RiBell]

Karl:
I heard about your airplane; and the fact that you are using A123's.
Where are you picking them up; as I have a project about the same size.
Rick

[karl k]

I got some static reading for those interested.

It turns out that I can use more prop. I think the 22x12WE from APC would be a good choice. Keep the ground clearance, but pull stumps when needed.

http://www3.telus.net/kethlerhvac/lanier_husky_build/3-10-08%20Husky%20with%2022x10%20APC.jpg

6139 RPM
76.10 Amps
2649 Watts

I think the motor mount will get updated before I change the prop, though.

Karl

Karl Karl Karl come on now, how much power do you need!!!

[karl k]

I couldn't sleep. I had this motor mount running through my head

http://www3.telus.net/kethlerhvac/lanier_husky_build/axi%2053xx%20motor%20mount.jpg

If I can get the local guy to cut and bend this, it will work perfectly.

The motor mount will no longer rub against the cowl and it will have enough torsional rigidity to stand up to anything I can throw at it.

The mount will actually hug the motor quite tightly.

I didn't take the time to mock up the motor in the CAD program. Maybe another day.

Off to bed for me now.

Karl

[karl k]

Karl Karl Karl come on now, how much power do you need!!!

Dave.

The punch out from a hover is lacking right now..... :eek:

Is that enough reason?? :D

Karl

[jrb]

This works well:

[karl k]

This works well:

The recommendations from Axi are to not radial mount the motor. After looking at the size of the motor and where the load is placed, I see why.

This motor is much stronger mounted in this manner. The bearings are loaded less and the motor bell doesn't have the chance of malformation and releasing a magnet.

I knew about the mounting requirements of this motor before I bought it. It didn't bother me to work around it because the motor had the kv I was needing to push a lot of power with the batteries I chose. Most of the high powered motors available have a lower kv which means I need to swing a much bigger prop that I may not have room for.

What I didn't realize is the diameter of the place in the cowl where I need to fit the mount in order to front mount the motor. It doesn't bother me. I like working around problems when you get to come up with a better solution than is available to just buy.

Karl

[steve1814]

Karl,

How much of a clearance issue are you having? Is there a way to just scoot the motor back a little and get a longer prop shaft? Your mount looks very nice btw.

Cheers,
Steve

[jrb]

The motor can be put inside too!

[steve1814]

Yes, I assumed that :) I hope you are able to get it milled as I'd like to see the outcome. I am trying to figure out of I want electrify a H9 Super Cub, so I am following your thread with all the enthusiasm of a little kid!

[karl k]

I should have clarified where the motor would be mounted. Here is a quick mock up with the modeled Axi.

http://www3.telus.net/kethlerhvac/lanier_husky_build/axi%205345%20motor%20and%20mount%20mockup.jpg

You can see how I still have a lot of room for the motor, but because the metal bends at the front instead of having a bolted connection, there are no "sticky outy bits" to rub on the cowl. This created a whole pile of clearance that I don't have right now.

Karl

[steve1814]

Karl,

Not to question your nicely designed motor mount, but won't this one (http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXMVU6&P=M) work? It can handle 63mm dia motors like your AXI.

Where are your batteries mounted? I did not come across a picture of that.

Do you plan on doing some aero-towing with it - It seems that you have the power!

Cheers,
Steve

[karl k]

I have looked into that one. The motor doesn't fit inside the mount let alone reach far enough. It will only adjust from 3.5-4.6". I need the spinner backplate at 7-5/8" from the firewall.

Believe me, I look for all commercially available options before I decide to design something for myself.

Karl

[karl k]

I've some new numbers for the stats geeks.

AUW 19lbs 13oz.

New power results taken in flight.

3025 Watts
7700 RPM
85 Amps

I guess that once the prop gets moving and can actually get a hold of the air, unload and increase it's RPM, it will draw some more current

Remember the fan laws?

CFM1/CFM2=RPM1/RPM2=√(Thrust1/Thrust2)=³√(HP1/HP2)

Where:
CFM = Cubic Feet per Minute of air moved
RPM = Rotational speed of the propeller
Thrust = Pressure built up behind the prop
HP = Horsepower required

This tells us that, for a given prop, if we increase the RPM by 25%, the CFM will increase by 25%, the thrust will increase by 50% and the power requirement will increase by 63%

I ordered a couple 22x12 WE APC props to bump up the static thrust a bit.
I should end up pretty close to the power draw I want, then I can start thinking about what to carry up with it :p
It should be able to carry about 10 lbs up into the air.

Any suggestions on what the payload should be?

Karl

[karl k]

Found a nice problem today.

It turns out that the speed controller has decided to forget how to make the motor spin.

No magic blue smoke. Castle link recognized all the settings that I had in the controller previously. Just to be safe, I re-loaded them all. Still won't start the motor, with or without a prop.

I tried another motor to be sure that the big Axi didn't die. No such problem, though.

I talked to my supplier for the ESC. He has another one on the way to replace the one that is giving me problems.

Has anyone else had problems with the CC 110HV controllers or similar products from CC? What has been the cause, fix, etc.. for the problem

Karl

[Geoff Dryer]

Maybe you flooded it :)

[Geoff Dryer]

I am surprised that nobody has commented on a similar issue with a Castle HV controller (or not). I know that all controller manufacturers seem to struggle with timimg issues starting large propellers but this problem seems to be some sort of electronic failure.

I was laughing too hard from your last comment.(flooded it :p )

Maybe ya just need to floor it and crank it for a while untill it clears out.

Castle does have good customer suport. They've replaced a couple of ESC's without question; (smaller brushed units) and once it might have even been my fault.
Rick

[karl k]

I do have a replacement on the way. The weather has been the pits, so it's not real disappointing.

The part that bugged me is hauling the monster to our temporary field and not being able to fly.

[Geoff Dryer]

So as you might recall Karl was having problems with his speed controller. Over the last couple of weeks it seemed to get progressively worse and appeared to be a timing issue. It got to the point that it would not start the propeller. We tried another motor and the problem persisted. Yesterday Karl received a brand new speed controller.

Today I watched as Karl spooled the motor up several times with no issue. First 5 minute flight with no issue. Second takeoff and the motor quits with the same noise. Karl bravely attempted to turn the plane around but clipped the tree.

It would appear that this is an issue with the controller. Karl had the Data Logger running so maybe it will tell us something.

[karl k]

Info from the data logger:

Max amps: 82.87
Min volts: 32.37

On the graph, you can see the current drop to zero as the motor cut out.
The recording stopped when the batteries were ejected from the airframe.

Cut-off voltage in the speed controller was set at 24v.

Does anyone know if there is a way to recover flight info from the castle controllers? Mainly if there were any errors on the last flight.

Karl

[jrtal]

Hi Guys,
Interesting threads! I noticed in post # 57 you said Deans plugs are hard to Disconnect.
I have found that if I plug male to female before soldering, this allows the connectors to stay in line ( and maybe loosen a little with the heat on the plastic ) and subsequent removal is a lot easier to perform.
Hope this might help.

Regards John R Talbot......

[karl k]

Here are some pictures from the bad day.

I have an e-mail in to both Castle Creations and the distributor where I bought the controller. I have yet to hear back from either of them. In both e-mails, I have requested that the money for the speed controller be refunded.

The Phoenix 110HV has failed the same way that it did previously. This time, it happened in the air and on the first flight instead of 15 or so flights later. I plan on making a short video to show how the motor is acting with the speed controller.
I did pick up an ESC from Hobby City like was suggested previously in this thread. I have learned that sometimes, you don't get what you pay for. The ESC from Hobby City was $100, and the CC110HV was $230+taxes. The cheapo esc starts the motor and runs it smoother than the CC110Hv ever did. Odd, huh?

I've been thinking about what to do with the equipment from the plane. It wouldn't be terrible if it went into a different plane.

I do like the way the Husky flew, but there are a few things I wasn't really keen on;

The color was too standard (ie red, white and blue). I do get tired of all the planes coming in this color scheme. I am not the greatest at covering planes, and recovering adds to the expense.

The strut arrangement was decidedly weak. If I do get another Husky, this would need to be addressed.

The lack of dihedral in the wings made it look like the wings were always drooping. All it would take is a couple of degrees to get rid of this illusion. I can't see a way of adding this into a model that is already built.

The location of the batteries made it very difficult to get at them. This made it very difficult to use the packs in more than one plane. I could probably design a better system in a future Husky, though.

If anyone has any suggestions as to what plane this power system could go into next, feel free to post here.

Karl

[jrb]

What do you think cuased the ESC to fail?

Could you summarize you set-up here once again; inlcude any measured data you had as well?
