Hangar 9 electric Piper Cub

[hrbeta]

I just would like to share my satisfaction with my new 6 footer J-3 e-Cub from Hangar 9. After being away from assembling models for quite a long time, I found this ARF kit very complete, well put together and true. All necessary parts were included, all of them fit each other, instructions are very clear and the quality of the materials is superb.
I just needed to add my radio and flight pack, a large 6000 mAh Li-Pol batt, a 70 amp ESC and a 15X8 prop to complete this bird in 3 nights.
This plane flyes like a dream for those of us who like tranquil, scale flying planes. The e-Flite 46 motor produces more than necessary power for short take-offs and mild aerobatics. The plane is stable and very well behaved. It'll fly at 1/2 throttle attaining 25 min. long flights with my batt set.
It lands very slow and short. I've flown it in 10 to 15 mph winds and althoug Cubs are known for their kite-like manners, the e-Flite 46 and this kit's sturdiness possitively counters any wind-shyness on behalf of the Cub. Neverthe less calm wind days are much more enjoyable with this pretty plane.
I highly recommend this ARF for us older boys who want a reliable, fun and easy going plane.
Cheers.

Looks like a nice model for relaxed flying. How many cells in the flight pack. Is it a 2 piece wing?

[Coastwatcher]

Tor-Dk,

The eflite 46 uses 4 or 5 cell Lipo set up. Plenty of power for a cub .

[Tor-DK]

Would 4S 3700mAh be enough for 10 mins flight?

I already have a few of those.

[hrbeta]

Yes Tor-DK it's a two piece wing. And I figure that you'd get some 10 min. flight time out of 3700 mAh with a minimum of throttle management :)

[Coastwatcher]

I agree, in this non pwr hungry plane a 4S 3700 should work well and I would expect 9-12 minutes with good throttle management.

[schoonerj]

I agree a very nice plane. I have not yet maiden mine, hopefully soon.

There is a thread another thread in the to Glow to Electric Conversion forum about mods for the this plane started by No Step.

With a plane this size, you could run 2 packs in parallel to get more flight time and not have any weight penalty.

[Dora Nine]

Just a little FYI, I found it easier to assemble the plane (at the flying field) with the bolt/lock nuts that connect at the fuse to be just the oposite as you have them. Meaning lock nut on top and hex bolt pointing to the underside of the wing. This way you aren't trying to grip on to the allen key or driver right next to the fuse. I also cut the bolts themselves down to make assembly a little quicker. So far even with the vibration of glow power...I haven't had a single issue. The cub is a well built, great flying plane.

[mcharles13]

I did this conversion a few months back and mine flies awesome. Here's the thread on it.

Jim, I sure like those flaps on your model. I started out by looking for a Super-Cub to get me some flaps but the best choice I found was the Hangar 9 J-3, so I did the best next thing, I programmed my radio to use flaperons. Tell you the truth, I have not had the need to use them, this plane is light and slow, but I like to know they are there. It's been a little breezy where I fly lately, I'll probably experiment with them when it calms down.
Cheers.

hrbeta, nice plane! glad you like it and it flies well.
However it doesn't qualify for this forum and should be over in 'Sport' since it isn't a glow conversion. This forum is for planes over 80" in wingspan.

[hrbeta]

Hey Tone, I'm sorry if I barged in :p

Here is the descrition for this Forum:

"Giant Electric Planes:
Discuss large electric aircraft that meet IMAA giant scale guidelines: minimum 80" wingspan, 60" wingspan for biplanes, 140" combined width and length for jets, or true 1/4 scale models"

I *thought* by stating "minimum 80 inches", my Hangar 9 Cub would be included (last time I checked the dictionary, "minimum" was an inclusive term). Also, this is not the chapter for conversions.

Police work is always hard, one would not want to be wrong :o

If me and my Cub are not welcomed here, just say the word, we might be allowed back in when it grows to, say, 80.000001 inches?

[tone]

heheh sorry about the mix-up, i just figured that the forum would not include 72" span models unless they are actual 1/4 scale, but it looks like yours is the 80" version. In your post you said "6 footer" and there are 72" cubs around, so i stuck my foot in my mouth..
Looking forward to more info as you go along.
Those E-Flite Power Series motors are pretty impressive aren't they?

[mcharles13]

hehe. yeah h9 cub is 80", but honestly it doestn feel giant scale to me. I want to do another giant scale that actually looks giant :) I was skeptic to post mine up here cause i wasnt sure, but i'm glad thsi thread popped up cause i could tag along :)

Hmmm!! hrbeta-you have brought out the purest-I have a hanger 9 elec.on floats and since I'm more use to park flyers it was a "gaint" to me. Thought your post was very informative -also thought this was for Elec. -Seems as no one knows what the "Qulifications" are .Think I'll go back to the "Kiddy" forums. Anyway i enjoyed your post -where ever you put it

[vector-g]

hrbeta,
thanks for starting this thread on the new electric H9 Piper Cub Power 46 ARF+ (it's about time :)) I bought one a week ago and will be building it soon. It truly is a quality built arf absolutely beautiful! . I like the fact the eflite 46 motor is already mounted and also the cowl is already attached. I will be using:

TP 4200 mAH 4S2P
CC 60A ESC
XOAR wooden electric props 14x7 and 15x8

All you Cub lovers out there lets keep this thread going! :)

[Michael in Toronto]

This is a great thread about a new trend (I hope) in the hobby.

I think it's great that Hangar 9 has come out with a large ARF with a large-size electric brushless motor, at a fair price. I hope Hangar 9 continues with new models.

I have a Hangar 9 Funtana 40 and a Hangar 9 P51D Miss America, both electric (conversion) powered. They're great products and I will continue to be a customer.

I built a Sig Cub a couple years ago (before Hangar 9 made it easier :D ) approx. 84" wingspan, and power it with an AXI 4120-14 and 4S 8000mah. At 7lbs 13oz, the plane flies very slowly. I would imagine that at a lower weight, the Hangar 9 Cub will be a gentle flyer.

[hrbeta]

I was surprised that the H-9 Cub had no previous thread in this forum, such a nice big electric model. I agree with the others this is no giant e-plane, but is a very respectable almost-1/5 model. At 80 inches, the H-9 Cub is shy of a full fledge 1/5 near-scale, by less than 5 inches.
Where I fly, one of the members flies a 1/4 model... Now, I think that is giagantic at 107 inches of wing span. Too bad is not electric IMHO :rolleyes:
This is also my first larger electric for lately I've flying convenient, midsize, fly-anywhere, parkflyers. I specially enjoy my Fokker DVII and my tiny TigerMoth. What can I say... I like them all :D but the H-9 Cub is at the top of the list right now.
I only wish I'd find a faster way to attach the wing struts to the fuse when I'm at the field. I have and idea that something in the spirit/shape of a motorcycle chain connector may do the trick. Anyone knows a handy fabricator? :)
Cheers.

[mcharles13]

assembling the wings at the field + cold winter has GREATLY decreased my enthusiasm for my cub. by the time i got the wings on i was freezing. now that it's getting warm again i'll be out there showing off my cub and loving it.

True. Attaching the wing struts is the most tedious step in setting up my Cubs at the flying field (I also have a ¼-scale Dave Patrick Clipped Wing Super Cub - Axi 5330 powered).

They are neccessary for flight, however, and they do add a nice scale "look" to the planes.

[staggerwing]

You can hinge the two outward wing attach points & leave them fastened for folding struts which leaves the single fuse attachment.
That can be made easier using a clip nut over either the fuse or strut plate so there is only the bolt to play with & using a socket hd bolt w/ washer epoxied to it makes that much easier.
The clip nuts come in most popular threads std & metric.
I use them whenever applicable on thin metal attach points on both models & ultralights.

[hrbeta]

Here are some images of motorcycle chain links. Imagine substituting the chain in the image, by the struts and the anchoring plate on the fuse. Then the link stems would penetrate into the 2 bolt holes from the top and be clipped in the same fashion as the chain from the bottom with the security clip :cool:
I fancy this would work :)
Now I need to find me a handy fabricator with a small lathe :)

[Thomas B]

This new Cub does appear to be a really fine offering from H9 and Horizon. I think one of the people in this thread (NOT me) is busy with the official Ezone review of this watershed electric ARF.

[justaguy533]

Hey GWH
New floats won't be out till May - here's pic of mine with first floats they offered- had to hand manf. mounts- pain in the butt!!! But plane is super!!

[Michael in Toronto]

I couldn't help it; despite having a near identical Sig 1/5 scale cub, I bought one too!

However, I'm coverting it to a military Super Cub.

I stripped off the yellow covering, installed flaps, re-did the windows square and with another bay of windows behind the wings, re-did the rudder to a Super Cub shape, installed a better tail wheel, and more.

I spent more than a week building a new cowl.

I'll post images when I'm finished.

[jimsz]

Sorry for asking a dumb question, but which of these two planes is being reviewed?

Piper J-3 Cub 40 ARF

Piper J-3 Cub Power 46 ARF+

http://www.horizonhobby.com/Products/Default.aspx?ProdID=HAN4350

[Thomas B]

The one with the Power 46 already installed.

The one without the Power 46 already installed would certainly not be a watershed event for electric R/C....;)

It would be just another ARF J-3, although certainly one of high quality.

[jimsz]

Thanks. :o

[Michael in Toronto]

Finished and flown.

I've wanted to build this model (in this size) for a long time, and finally did it.

The Hangar 9 Cub is highly modified: new shape in front fuselage, more windows, new customized cowl, new tail out-line, flaps, Robart landing gear, airfoil-shaped bungee covers, new covering and paint, homemade decals, new Sullivan tail wheel, pilot and some interior decoration.

Flies great; especially fun with flaps.

[Eagleburger]

She is a beaut!

[No Step]

Nice, real nice! I just looked at mine and the structure back there. The mod looks easy, just a little ply to be removed. Did it make the fuselage "twisty" at all. You didn't take any detailed pics just before covering did you?

I agree flaps are loads of fun.

Nice job!

[hrbeta]

Very nice job Michael :) Can you please post some details on the flaps' work? I've been using my TX's flaperon function but I reckon real flaps are more fun.
Here are some pics of my new 85% scale tail dragger :D :D
Just kidding :p This pics I took yesterday in Sebring, FL. My pal Danny Nelson took me for a ride on his Foxkit and I sure had a blast. Got to fly it most of the time (NO landings though) This little plane is what sport flying is all about: fun, simple and cheap :D This baby stalls at only 37 mph but cruises at around 105 mph. I hope you enjoy them.
Cheers.

[Michael in Toronto]

The fuselage is strong and not "twisty".

Here are some photos of the fuselage and flaps before covering.

I am reviewing the H9 Cub with Power 46 for the Ezone. I got a quick flight in this morning before the strorms rolled in to the DFW area. Like everyone else has said it goes together well and flies really well. Here is a picture Ronnie Pope (dawnron1) took for me during the flight.

[BillPTC]

I took the ARF and converted to Power46 before this was available. Using 2ea 7 cell 3600 Nimh on 13 on 13x8E APC prop and Castle 60. Get 6 to 7 minutes flight. Have two EVO 4350 4 cell LiPo but have not tried it yet. Have to enlarge opening to get them in. What flight time is anyone getting on LiPo ?
Also got a set of Robart cub gear. Has anyone attached these?
If so did you have to use more ply? Did you fill in the current landing gear grove? Did you use the Robart blind nuts? How did you get around the 4-40 bolts holding the strut straps on bottom of fus?
HELP PLEASE

I use the Robart gear. It really smooths out landing and taxiing. And they look great.

I filled in the grooves; I used the Robart blind nuts; I drilled holes in the aluminum strut holders to allow the landing gear screws to stick through. It's tight and complicated, but it works.

No additional plywood was needed.

[surfimp]

I picked this plane up a while back and have been too busy to finish it till today.

My setup:
E-Flite 46 (came preinstalled - nice)
Castle Creations 60
14 x 8.5E APC prop
5S1P A123 pack (from http://www.bigerc.com/)

According to my Watts Up, the above setup pulls 52amps static at WOT. I am hoping for at least six minute flight times with the A123s, we'll see. I also have a ThunderPower 4S1P 4200mAh pack if the A123s are disappointing.

I have the ESC setup to have a 4.0V LVC cutoff...basically no cutoff at all. I have my Tx setup with a timer so it reminds me when to land. This seems to be the current strategy for successful A123 flying.

I taxied around in the driveway, this plane is gonna be fun! Hope to maiden it tomorrow. Very nice plane to build, excellent quality throughout.

Steve

[drksyd]

Nice! Good luck with the maiden.

[surfimp]

Well I got the J-3 up for its maiden flight and it flew great. Needed a bit of down trim and a bit of right aileron trim, but certainly no bad habits at all. Very easy to fly plane, and easy plane to fly in a scale manner.

Power was good with the 5S1P A123 cells and the E-Flight 46, I found I was mostly flying at around 1/3-1/2 throttle. Batteries were just barely warm when I landed, I started conservatively with timed 4 and 6 minute flights, but I think I'll be able to get 8 minutes pretty easily. That's not bad for a battery with only 2300mAh capacity and propped for 52amps static!

Did a couple rolls, a few loops, tried a spin, but really for me this plane is about flying the pattern and doing touch & goes and landings. Normally I fly slope gliders so having an actual runway is a real treat... flew a number of slips to landing, the Cub does these awesome and with panache. Very controllable, it's everything I was hoping it would be.

Handled the standard 10-15mph quartering crosswind at this site with no worries... so glad I went with a bigger plane for that reason.

The main thing I found fascinating is how much my fullscale taildragger experience translates directly to this plane. It really does seem to fly like a miniature J-3! Very cool.

A club mate snapped some in-flight pictures, see below.

Really enjoy this plane,

Steve

Next up for mine, I'm going to get a 1/5 scale pilot to go in the back seat so it looks proper in the air. Trying to decide between two Slimline offerings, "Curt" and "Gramps"... I like both, maybe I should get the pair? But then who gets to "drive"? :D

Which pilots are you guys using for your Cubs? I ended up going with the Slimline "Gramps" which I figured was just about perfectly in between 1/5 and 1/6 scale. Didn't see a lot of other solutions, hope this one fits well (it should, based on my measurements).

Oh, and I already know that you solo a Cub from the back seat, but thanks for the subtle hints ;)

[mcharles13]

Nice shots steve.

I need to borrow your camera man. :)

I'm glad you like the a123 pack.

,mike

[surfimp]

Had some more flights this morning, I'm easily getting 8 minute flights with this setup, and putting about 1800mAh back into the A123 pack. There's still plenty of power at that point, too. I can probably bump it to 9 minutes without concern, especially as I'm running a separate receiver pack.

Got a lot of really positive comments about the plane today, saying that it looked great and that I was flying it very scale. I got a number of very nice wheel landings in, including a one-wheeler that was a spitting image of the landing in the Hangar 9 promo video. No one could believe the plane was only $299... :cool:

Steve

[surfimp]

I'm going to gush a bit more about this plane... while it is nothing more than a humble Cub, it sure is a lot of fun to fly! Got a short three flight session in this morning, the A123 packs are just great.

I have a digital thermometer and even after my hardest flight they come out of the plane at 90-100*F or less (once time I pulled it out and it was just a hair over ambient temperature). I put 1900mAh back into that particular pack, after having around a nine minute flight on it.

Power is so good I am normally climbing out at just a couple notches over half throttle. This is a scale climbout, around 20* or so... not vertical but hey this is a Cub!

The advice I got from some to swap the E-Flite 46 for an E-Flite 60 or comparable was a bit off... with 93watts/lb this plane does not need any more power than this to fly in a very safe and satisfactory manner (with the APC 14x8.5E). At full throttle it really moves out, I could dodge and avoid almost any problem or very rapidly power out of a landing gone ugly.

Anyways, strongly recommend this plane. I was in the hobby shop yesterday and was informed that someone had come in asking about this plane, after having seen mine fly... :D

But there is not a good place on the wing to mount the floats so I had to put them on the top side. :D

Finally got my Slimline "Gramps" pilot figure in yesterday... it fits perfectly in the J-3's cockpit area.

As soon as I saw the figure online, prior to purchase, I knew I'd have to add a cigar as a "finishing touch." So I quickly fabricated one out of a small piece of brass tubing, then made the ash tip out of baking soda hardened with thin CA. Next I broke out the figurine paints and brushes and did a quick paint job... I'm tickled pink with the result! And "Gramps" seems to be enjoying his puro quite a bit :D

[Dora Nine]

Guys, there are pics in my blog of my H9 Cub and floats.

Justaguy...the back support couldn't be easier to add. If you are still building your cub, you should be able to add the included support without removing the covering. I would have done it from the inside if it wasn't for the windows and push rods being in the way. Instead, I just followed the instructions and ironed on the included peice of covering--it was little long, so I trimmed it down to fit. Aside from that, good to go. I think the entire process took an hour.

Also, make sure you go over the floats with your iron and re-seal all the seams. One of mine is peeling a little. No real biggie, but I think I am going have to either re-cover the float or glue it on. Subsequently, the float has/had a small leak. It may not have helped that the plane was either in the water or flying for nearly 6 hours the other day. :rolleyes: I'm loving these floats. I doubled the flight time on my cub since I got these floats..:D

[justaguy533]

Yep! After i looked at it a while didn't seem as much as thought. I added my back support with out cutting the covering-I'm not real comfortable doing that yet.Works greatafter got sevo going correct!
Thanks

[Dora Nine]

Anytime. Don't fear the covering. I've never covered an entire plane yet...only small pieces...it' seems to be pretty easy to do patch work atleast. I'm glad things worked out well for you though. Make sure you check the covering on those floats!

[justaguy533]

Thanks for advice- float covering does have couple wrinkles-do just hit them with heat gun ?

[Dora Nine]

That would work, however you want to go over the seams with a covering iron to make sure they were sealed well. No joke these things were made by cheap labor... and yours could have been made late on a Friday afternoon.

[BillPTC]

Got my Robart gear mounted. Put a sheet of plywood between the rails inside. Moved the gear forward a 1/4 inch and missed the strut strap inside with 4-40 bolt and lock nuts. Works great. Picture attached

[Dora Nine]

Bill, can you post a pic showing one of the two struts with a load on it (ie pushing down with fingers)? This way we can see how the spring action of the gear works; and see how the other looks while at rest. Thanks!

[Rudderman98]

I changed the attachment for the aileron servo connection by incorporating the Graupner "Quick-Fix" Wing Plug-In Servo Connectors from Hobby Lobby.

http://www.hobby-lobby.com/hookup.htm

Basically, you have a male and female plug just as you would your servo leads BUT, you can attach two servo leads to one connector. So in essence, one flap and aileron servo to one plug instead of two individual servo leads. Also cleans up a lot of wire clutter inside the cabin.

So all you have to do to attach your aileron servo lead is to just attach the wing. Plug and play!

The ply plate that is used to attach the connector is identical in the fuselage as is the wing. I am getting with a friend to laser cut these ply "inserts" for the fuselage and wing. You will have to epoxy them into the fuselage and the wing. There will be a recess etched into the ply plate for the connector holder to sit flush in. That's the white piece.

These type of connectors have been used by the sailplane guys for years without any problems. Instructions are included with each connector package ( male and female) on how to solder your servo leads to them. It's easy!

If anyone is interested in purchasing a set of four ply plates to do this mod, (2 fuselage and 2 wing plates), PM me. (THIS DOES NOT INCLUDE CONNECTORS). They won't be ridiculously expensive. I'm not out to make a bizilion dollars on this idea. Just helping out us Hangar 9 Cub owners make a nicer and easier to set up plane. You will have to trim these ply plates to fit just a bit for each model for I am sure each plane has a bit of varience in the sizes of the openings. But the fit will be close.

I'll post more pictures of it once it is completed. Please be patient while we get the design for the plates in order and to make sure they fit correctly.

Getting close to my maiden soon!

I also use the Robart struts on my Hangar 9 Cub.

They really help smooth out taxiing, taking off and landing, and they look good too.

Bill, thank you! If I can convince myself to take off my floats...I'm gonna have to get those. Maybe this winter with some skis?

[jrb]

Did somebody say Robarts & skis?

[Michael in Toronto]

I've received a few requests as to how I changed the front section of the fuselage to have the profile of a Super Cub.

These images give a basic idea as to where I cut out wood from the fuselage, and then re-glued the floor in the new position.

[Dora Nine]

JRB: Sweet... thanks!

Hello all,

Here's a photo I took of gwh's Cub on floats at our city lake :)

[Dora Nine]

Dawnron, beautiful! Did you guys experience any leaky floats? I gotta do a little water proofing with the rudder side float. What sort of flight times are you guys getting with your electric Cubs?

And just for fun, I'll add a pic of mine. :) Although I hope I don't offend anyone because it's glow powered :eek:

[Uncle Chopper]

Thanks for all who contributed to this thread. I just got a Hangar 9 Cub, and can't wait to get it together.

[gwh]

Dora,

I made several flights on the floats today. I had added a strip of clear packing tape down the middle on the bottom of each float from the step forward since I had worn the covering thin by running on grass extensively. I did not notice any leakage, I could not hear any water sloshing in the floats and the plane did not appear to sit any lower during the day. The flight times are pretty good 8-15 minutes depending on the battery.

[Dora Nine]

GWH: Glad things are working well. I still have a leaky float...nothing some more 30 min epoxy can't fix. :) My cub is glow powered :eek: and flight times are about 20-30 min...sometimes shorter due to high heat and humidty. Still very happy with the plane and floats. Actually the other day, I swapped the floats for gear and did some touch and go's at the local club field... such a a great plane. :) And being able to swap out the gear in 5 min is another bonus.

And being able to swap out the gear in 5 min is another bonus.
It's even quicker to spray the floats with Lemon Pledge.

Here's another from the 'Lemon Pledge Grass Takeoff Series' :D

I wish my club field was that flat/smooth. :eek:

This is how my Hangar 9 J-3 40 PNP arrived. I'm not a happy camper. Not a single mark on the box, but smashed rudder, gouges in the fuse, CA glue white residue everywhere, where CA was splashed and wiped with acetone.

Even the decals look like they were cut-out by a 2 year old.

I have to give this plane a 0 out of 5, from my experience right now. This is how it came, straight from the box. Pics below. :mad:

After I get a refund on this plane, no more Hangar 9 products for me...my first and last. :mad:

This is how your plane came straight out of the box??

I have a feeling that your plane was already owned by someone else and that it was placed back in the box and returned noticing how the elevator support cables were already installed and that thay are NOT installed from the factory. At least mine weren't.

Also the rudder and elevator controls are installed and thats not how they come in the kit. I have been very pleased with my Hangar 9 Cub. You might want to reconsider your thoughts on the brand. I believe you got duped on this deal. That is not good! :mad:

Any takes on this guys?

Shame on Hangar 9 for such blunder. No wonder you're so mad, Charles. However I agree with rudderman, if you get satisfaction from H-9, give the brand another chance. They are definitively one of the very best ones out there.

[drksyd]

I'm not sure if the linkages are already connected for a pnp arf but I highly doubt that it left the factory in that condition. I think Rudderman is right that someone returned it in that condition and they didn't check it when they got it back or sent it. I like the H9 kits myself, they look good and fly great at a good price.

[r1derbike]

I've decided to give H9 another shot. It could very well be this was a returned item. I have heard nothing but good about H9.

I'll be receiving another Cub shortly. I'm hoping it is not trashed.

Somebody dropped the ball on my Cub. I don't know if it is a factory or dealer issue. At this point, I don't really care, but I will give credit publicly (here) if the new one meets expectations.

I just finished my H9 Cub and it was flawless out of the box...

[AirFoiled]

I picked this plane up a while back and have been too busy to finish it till today.

My setup:
E-Flite 46 (came preinstalled - nice)
Castle Creations 60
14 x 8.5E APC prop
5S1P A123 pack (from http://www.bigerc.com/)

According to my Watts Up, the above setup pulls 52amps static at WOT. I am hoping for at least six minute flight times with the A123s, we'll see. I also have a ThunderPower 4S1P 4200mAh pack if the A123s are disappointing.

I have the ESC setup to have a 4.0V LVC cutoff...basically no cutoff at all. I have my Tx setup with a timer so it reminds me when to land. This seems to be the current strategy for successful A123 flying.

I taxied around in the driveway, this plane is gonna be fun! Hope to maiden it tomorrow. Very nice plane to build, excellent quality throughout.

Steve

Steve, I been looking at this plane for a while and I also felt that it would be a natural for the A123 packs. On your 5S1P pack what was the configureation? (Flat, Brick, hump ect.) Does it fit ok through the battery hatch door? Would a 5S2P fit?
I assume you are using a seprate reciver pack.

Just did a Maiden voyage of my Cub. Man, she is beautiful. Need to do some work on the trims, and some mixing before putting her up again.

Got rained out here in FL today!
