Jetset44 F-14 Parkjet converted to Twin EDF

[FL62]

Hey guys, just thought i'd share my latest weekend project - a Fanfold Parkjet F-14 designed by Steve Shulmate (Jetset44) which is designed for Pusher Prop power, which I have converted to Twin Brushless EDF.

The controls are Full Flying Tailerons, Adjustable wing sweep, and Throttle
The Plane was built per his plans, with the exception of taileron servo mounting to better accomodate the fan ducting. The inlets are stock, with an intake ring at the front of the fan, and Photo Paper exhaust tubing at 100% FSA.

AUW is 26oz's, and the measured thrust is 22.3oz's
Power comes from two Wemotec Microfans, each with an Astroflight 010 8T Motor, Phoenix 10 ESC's, and a single 4s 2600 Li-Poly.

A quick shopping list put together by a great member Awnesh:

Okay Mike Now I need to get one of these. You are getting me in trouble! :)

[RoyHolder]

YES, where did you get it?

[FL62]

:D
I plan to keep this one around for the Jet Rally - I want to see the look on the turbine guy's faces when I tell them it's made from $4.00 in Fan Fold Foam!

Thanks for all the positive comments guys!

It's actually all Kevin Cox's fault - his darn F-18 is what got me hooked on EDF - just look at my avatar :rolleyes:

[the agent]

wow great job, you wouldnt happen to have photos or measurements of where the fans were placed?

[AirX]

FL62,

How did you launch, hand or bungie?

Pretty sure he hand launched it, it's only 26oz's...

[Chris Nicastro]

Cool Mike, what did you paint it with and did you fill in the seems on the canopy or nose with anything? Looks great for a foamy!

Chris

[jetset44]

I've already commented on the fantastic flight performance of this bird, but now that I've seen close-up pictures I can say great work on the paint job and detailing, too! Is that the Aggressor squadron scheme?

I'm especially impressed that this setup works so well with the carbon stabilator pivot rods running across the aft fan duct. Keeping those rods keeps construction quick and easy, so it's great that this still allows good performance!

Steve

[Thomas Nelson]

I am very impressed!

Are you using Mr Boogies intake ring - or something of your own devising? And you didn't make any special ducting! Only simple thrust tubes.

Excellent!

[Ron Laden]

Fantastic, looks very smooth and predictable in flight, good low speed handling as well, great job.

Ron

[bipeflyer]

I have to agree, that is a fantastic model,will guarantee to turn heads wherever it is flown,it has made me want to follow suit with an EDF version,this has to be the best model ,or at least one of them, to come out of 2005.

Well done to Steve for releasing this design,and Mike for making the truly convincing EDF conversion. Best of all, handlaunches and goes like a Tomcat should! :D

Matt, certified F-14 obsessive :)

[U812]

I'll second that Matt. Outstanding.

Steve

How are the astro 10's handeling 4s lipo's and how many amps are they pulling?
Very cool F14 by the way.
Dr'e

[Mr. Boogie]

FL62,

Very nice execution! She flies with authority and looks good zipping by.

You mention that you used 100%FSA at your outlets, does this mean they are not tapered?

Mr. Boogie

[FL62]

Thanks Guys!

C of G - I used Krylon H2O Paint for the Base Gray, and then brushed on Dreamcoat acrylics for the other colors. No fillers have been used. Fan Fold Foam leaves alot to be desired for smoothness and texture of the surface, especially after sanding!
I intend to build another out of depron, now that I know the Prototype works :)

Steve - The paint scheme is my loosely hand painted rendition of the "Splinter" scheme seen on Chris's Bigger F-14 EDF Last year, one of my favorites!

Tom - For intake rings, I simply layered 3 pieces of Fanfold together to make a bulkhead, then cut a hole thru them at the O.D. of the Microfan. The Fan is mounted to the back of this bulkhead, up to the molded ring on the fan housing. I then simply hand sanded a 3/8" radius into the foam forward of the fan. It gives the same effect as taking a GWS EDF55 and sanding the inlet ring square! I'm not sure, but a little "Duct smoothing" might be useful where the wing box and linkage goes across the duct, as there is none on mine. The Carbon torque rods in the exhaust tubes, and the Wing box in across the intake kind of go against the holy book of EDF ducting, but sometimes I think that the loses are so small it just isn't worth it to over re-engineer the plane. It would be interesting to see if cleaning up the inlet ducting would make a difference.

GBruce - Always gotta have some Nickelback playing in the back of my head on those low speed passes! :D

Dre' - The Astro's seem to hold up fine in this application. This set of Motors and fans are very well used for over 8 flights now in the Cat, about 10 flights in my Jetset44 F-15 EDF, and previously countless amounts in a GWS A-10, all on 4s Lipo. The setup pulls about 12-13 amps on each fan, so I have the timing on the ESC's set to low.

Boogie - The ducts are 1.625" Dia at the outlet, which if my poor math is correct, is about 100% FSA for the Microfan (at 2.05 Sq In). The ducts have a small taper to them into the simulated Jet nozzles - which are cut from a top secret material - Dixie Small Paper drinking cups! :cool:

[FL62]

Paul - That Styrofoam F-14 looks pretty cool (I believe it's the forthcoming Align one), but I think it would be too heavy for this power system. It is quoted to be 850-900g AUW, which is over 30 oz's already (and the EDF conversion would be heavier), and a wingspan of 31" to 43". Now if you could stuff a couple of brushless 65mm fans in there it would be another story!

the extra weight is a problem indeed. I will get the guys to send me the measurements so I can see if I can get 2 x Alfa 60’s in there.

P.S if you want me to remove my post that’s fine, as this thread is supposed to be about your F-14 LOL and the bold heading was bigger than i anticipated. :p

What dose you F-14 weigh RTF?

[FL62]

Paul-
No reason to remove your posts :)

Mine weighs 26oz's AUW with Batteries. I would be interested in the info on that styrofoam F-14 you posted, as I am thinking twin Vasa 65's, or maybe even Minifans :eek:

Where do you get those EDF fans? Great Plane!

[beanie]

fl62... looks awesome.
did you use the hitec hs81mg or the 85mg or 85 for the wing servo mechanism?

Beanie - I used a Hitec HS-85MG on the wing swing mechanism.

[Electricman]

FL62- You use their speed controls without any issues? Did you just wire them up together to the reciever?
That place that sells them is only 35 min form me :)
What are you flight times with the 4 cell 2100?
Thanks,
Chad

[Sal C]

FL62,

Are you using a UBEC? I don't think the CC10's can handle the 4S...

[monkamarm2000]

awesome bird. I've had the astro's in my RBc A-10 for almost a year now and there great little fans, very efficient.

Barry

[pacro]

can this baby do ROG

[FL62]

Sal - they are quoted for up to 12 cells (Ni), and I haven't had any issues yet :) Only one BEC is connected

Electric - Flight times with the 2100 4s are about 4-5 minutes, with the 2600 they are around 6-7 minutes with alot of "barnstorming" going on :D

Pacro - the plane has plenty of power to ROG, I just need to add gear. I may build another from Depron, and plan to add micro Retracts to it.

[pacro]

look forward to seeing this guy on wheels

[roccobro]

Wow, you've done great! Thanks Steve(jetset44) and FL62 for keeping this hobby great!

Justin

[jetset44]

By the way FL62, if you (or anyone else) is thinking about building another one of these here's something to consider.

I based this design on a true scale outline of the F-14, and took only one significant liberty with it--I increased the vertical tail area by 20%. I've done this on all of my park jets, with the reason being that a little extra tail area is needed to combat the torque and gyroscopic forces of the large diameter pusher prop. But if you're doing an EDF model that need goes away, so you could consider reducing the tail size 20% to make the airplane more scale in appearance. My eye can certainly tell that the tails on this model are a little bigger than the original... ;)

The only reason you wouldn't want to do this is that the F-14 already has a poorly damped dutch roll mode with the wings swept fully aft, and the larger vertical tail helps improve that. Thus, with a smaller tail you might notice the airplane oscillates a little more at high speed when the wings are fully swept. Not too big a deal, though. So it's your call if you want to trade this little handling quirk for a more scale appearance.

Steve

[roccobro]

Thanks for the info Steve. You've always been a great asset.

Justin

[FL62]

Steve,
I don't think i'll mess with an already great design.

My motto has always been to leave well enough alone.....


OR WAIT, was it to never leave well enough alone? That is how I keep ending up with EDF versions of your already great parkjets! :D

[eliworm]

Mike, Whats the plan for work tonight? I was thinking a mini F-14 with 1 or 2 Feigaos. I'll bring the foam.

Jim

[FL62]

I think i'll be the only composites guy there tonight, so I expect to be really busy :(

[tbitz]

Ran a doppler on one high speed pass. Kinda hard to pickup the tone of the EDF with the music in the background, but I think I got one. I calculate 79Kph (49mph). Not sure if this was the highest speed pass though.

Tony

[FL62]

Tony,
I can convert some of the video footage and leave the music out. I'd be interested in what figures you could come up with using the Doppler method.
49mph doesn't sound too far off though - whic part of the video did you measure that at?

Thanks
Mike

[tbitz]

I used 33 seconds into the video.

[jazsop]

Mike I Hope We Can Get Together And Do Some Flying If You Know What I Mean ! Love Jazsop

[jazsop]

Boy, don't ever leave your computer signed on at work with abunch of jokers who love to kid around. fl62 is not gay, and neither am l. For the people l work with, your time is coming. love jazsop

[FL62]

I SURE AM GLAD Jazsop is a woman, because otherwise those previous posts would sound really, um.... well.... funny?!? :o

[pacro]

someone should work out a deal with Steve to do CNC cut kits of this suberb jet since 3DFoamy is down for a few weeks (plus i dont think they'll jump right in to doing this F-14). just to make it eaiser on some of us "not so good at cutting templates" guys. also to supply a nice kit
just a thought

oh and FL62 what happened to the under fuse canards at the jet

[Veloc-E-raptor]

Just read this, great conversion!
(Gives me hope for my (slowly) growing F22!)

[darren jakel]

Awesome plane Mike!
I want one.

Darren

[Mihelich]

Mike,

Very nice converson indeed.
Can you tell me how far the fan (blade front edge) is into the nacelle?
Just trying to get a feel for where you have it located in the duct.

Thanks,
Tom

[Sal C]

FL62,

I think you and Steve should get a cut from Wemotec/Astroflight, after seeing this I think a lot of Micro Fans are going to be disappearing from the shelves. I was going to build the F-14 as a pusher originally but now that's changed. My MicroFan order is on enroute :).

[FL62]

The front of the fan unit is at the leading edge (tip) of the stabilator. This was "scientifically calculated" :rolleyes: because this is the widest point in the hull.....

[tbitz]

If you have another video with a high speed pass you want me to run a doppler, just post a link.

Cheers,

Tony

[Chris Nicastro]

Ok, got the Depron laser cut and we are on our way. Twin GWS EDF55's with 5400Kv motors is the plan. Photos to come....

@ Steve,
I want to send you a check so can you PM me with your info please.

[pacro]

will GWS EDF-55 work as good with the same BL's motor as Wemotec microfans

[FL62]

Pacro, EDF-55's are a little bigger, and load up the motors a little more that the Wemo micro. They do make more static thrust, but at a lower velocity...

Your motor selection would have to be a little lower (in kV) that that of a Microfan. A 4000-4200 kV motor in that fan is a nice setup on 3s LiPoly

[Mihelich]

Mike,

Thanks for the fan placement info.
I noticed that you did not mention if you have the rudders
hooked up or not in your frist post.
Are you using the rudders or are they fixed?
It appears that they are fixed in the photographs you have posted.
You seem to have very nice control in the video if you are not using any rudders.

Thank again,
Tom

[FL62]

You are correct - there are NO rudders on my plane. I felt that they would be of no use for conventional flight of an aircraft of this type. If you were building it for pusher power, and planning to do some "3D" type high alpha manuevers, they might be useful.

[pacro]

but then if you want to be able to slip in the EDF-55 units you would need to enlarge the plan about 5-10%

[AirX]

I agree with FL62 that the 2015-5400 is a bit small for the 55mm fan and will not run efficient and will produce a lot fo excess heat. If you do want to run the high kv motor in the 55mm fan go with the 2025 length motor as it will produce more torque and less heat. The amp draw for the 2025-5300 in the EDF55 on 3s is 22-25 amps so the smaller motor cant turn the rotor to the same rpm but will draw 18-20 amps.

Eric B.

[ALtitudeap]

i would be interested in some laser cut depron "kit". I have 2 edf-55 fans with cdr motors. i get 11 oz of static thrust from each motor. That would rock.

[Chris Nicastro]

I just happen to have these on hand and I know what they can do so I'll just make use of them. If you want to see what they can do in a vid of an A-10 go to www.e-flightline.com and look in the video section for the Himax 5400Kv EDF 55 combo. Im going to cut the lip diameter down and smooth the intake inside the fuse upto the fan that way the fan unit will drop in.
This plane will be so light anyway you can power it with just about whatever you have sitting around. Those GWS fans sitting on a static test will see more stress than unloaded up in the air and with some TH use you will still have a nice flight time with plenty of power to climb vertical on command.

I have a pair of Vassa 55 fans but I have a bad feeling about those causing RF noise, I lost my A-10 due to a radio lock out that was unexplainable but everything worked fine after.(should have used PCM maybe) The guys who fly the Vasa F-5 say the same things. With those I had over 600g static thrust and 36 amps combined.

I think with this F-14 a better choice would be higher thrust since its not a sleek cat anyway. Its not refined and purpose built for speed so a higher efflux fan will be working hard to get the plane up to a speed it will never see. But thats what trial and error is all about right?

[AirX]

That is a common misconception that the fan unloads in the air as the efflux is always much higher velocity than the flying speeds which would indicate the airflow has to be sped up to meet that exit velocity. Since this is the case there is no way the fan unloads in the air and it does work every minute of the flight.

Even E-flightline had problems with heat generated by the motors, the battery was also a problem as it get very hot. I exchanged a few posts with them on this subject so I know was happening in the 5400kv EDF55 setups.

It is your choice and good luck.

Eric B.

[Chris Nicastro]

Sorry, but the amp/torque loads on the fan in a static test are different from the loads in a dynamic test. They are two different situations, you cant have the same result. Thats like saying dont change your boat prop for salt water from fresh water, "I dont understand its the same thing" ahh...no, its not.

I spoke with Mike on the phone about these set ups. The batteries from a year ago or even 6 months ago dont compare and this type of set up is no longer a big deal. Yes the motors can come off hot, but thats what the throttle stick is for, some guys forget there is something in between on and off.
The motors can take heat, to a point, and I temp motors on bench tests all the time. I have spoken to motor companies who admit the motor specs are conservative. They are delighted to see some guys push the motors to performance levels they even thought the motors couldnt reach, and they hold up. I dont do this to mine but like anything else moderation is a good thing.

Chris

[AirX]

I do have to disagree with you, there is no comparison to the salt water and fresh water props here. There is also no comparison to an impellor and a propellor, your anology tries to compare density of fluids, the reaction of a 1.6 diameter column of moving air and a 6inch diameter whirling column of moving air are providing the the same effect. The difference is to produce enough force to move the airplane the smaller column has to move at a much higher velocity than the airmass from the propellor, Lets say the propellor tops out early say 60mph, the column of air for the 1.6 diameter outlet will be flowing at 90mph but the drag of the airframe will limit the max speed to 60, in level flight it will still be loaded. Even if the plane went straight in the EDF will not unload completely. Ted Goodwin has the Eagletree inflight data systems and has measured the amp draw while in flight:
http://www.rcgroups.com/forums/showpost.php?p=2652887&postcount=1
His thread deals with temperature of the motor not focussing on the amp draw in flight but you can see the graph gives a good idea that is does not drop off and this is at 120mph with an efflux of 156mph. Clue #1 propellors and fans are different.

Cheers,

Eric B.

[FL62]

Just posted another video in my gallery (f-14raw.wmv) - it is just the first portion of the flight, with no editing or music - hopefully Tony can get some doppler speed runs from it when the battery was still fresh! The 49mph doppler reading was taken at the 33 second mark in the first video, which was basically straight and level flight (which is great!).

http://www.rcgroups.com/gallery/showphoto.php?photo=19608&sort=1&cat=500&page=1

[Chris Nicastro]

My analogy is simply comparing someone who says two different situations are the same, not props to fans or air to water. Please read it carefully.

I wish I had telemetry to look at this closer but I can put temp meters in the plane that have peak temp memory, I want to see the amps too. I have the Nomadio Sensor radio coming on the 16th and it has live telemetry for temp, speed/rpm and batt. voltage. I can install the Rx with the sensors alone to transmit the live data then DL it to my PC. I'll take some bench test info I have to compare that to.

Anyhow this is getting way off topic so back to the cat!

Chris

[Chris Nicastro]

I was weighing the fans, Vassa and GWS and I remembered in a post before that one of the lightest combos for a 55mm fan was to take the rotor from the GWS and put it the Vassa shroud. I lost 6g doing that so 12g for two. The Vassa fan shroud is slightly smaller and it will install better in the Cats fuse.
@FL62
Your Cat sounds pretty mean! How many flights do you have on it and how is it holding up? Lets see who can beat your doppler speed run! :D

[roccobro]

I heard that a potent and rigid setup is the Vasa rotor in an GWS housing. The vasa tends to be a little flimsy and needing some extra CA in places-especialy after a hard landing. I don't understand why the Vasa rotor has to be so dang heavy. That adds inertia to the fan (not really needed) and weight on the tip of the motor shaft. Oh well. :)

Justin

[AirX]

I went back and reread your post, but I still disagree with you. I have posted my case and the evidence that substantiates it. But like you say it is getting off topic. Good luck on the F-14.

This airframe has turned out to be a nice looking and performing airframe, might be able to get one built in the coming weeks.

You want to laugh? The GWS fan with the Vassa rotor is 26g (on my scale that may need a recharge on the batt.) The Vassa fan with the GWS rotor is 16g! The GWS rotors are 4g lighter and the Vassa fan unit is 2g lighter. At least with the GWS fan in the Vassa unit I can get a tighter tip clearence, for what its worth.
I'm only contemplating this combo because the carbon on carbon fan unit seems to make some RF noise and the plastic GWS rotor might not.

[FL62]

Thanks for running that Tony - it is interesting to hear that my assumptions were close (I figured it was going about 50-60 mph tops).

Not bad for a "Parkjet" :D

C of G-I've read alot lately about the carbon/carbon Rf noise. Tigh tip clearance is a good thing too. The Vasa rotors are the expensive part of the unit, while the GWS rotor is cheap. Nice.

FL62- I agree, 50mph isn't bad for a parkjet! Good job.

Justin

[jetset44]

Agreed, 50 mph isn't bad for a "park" jet.

But the cool thing about your model is that it SOUNDS like it's doing a hundred with the turbine-like scream of those fan units... :cool:

Steve

[Chris Nicastro]

I have heard about guys grounding the carbon fan shroud somehow too. I have done it before on a Rx in a car but not a plane let alone a fan. I understand the Heli guys have done it on the carbon chassis too.
Its going to be subject to a long range full power range test anyway.

50 MPH!! Is that all she's got?? lol thats too cool, cant wait....who will go faster???

[FL62]

Hmmmm...... Faster?

This is why I always spend too much money - someone always has to challenge me :)

Now where'd I put those 5s Lipo's ?????

[Chris Nicastro]

LOL....go for it!!!

Your model has Micro fans, mine will have the hybrids I wrote about I wonder how they will compare in flight.

[FL62]

Oh, you don't even have to worry - mine will be faster!!!! :D

j/k - it will be interesting...

I have some depron on the way, so I can try building a lighter version, with retracts, and MAYBE a little (e.g lots) more power....

there is no such thing, but the Phoeinx 25's would be fine :)
this can

well i got this 20 amp esc that i have been using fine with these motors will they work for this plane

[FL62]

Pacro,
You need to provide more info than "...i got this 20 amp esc that i have been using fine with these motors will they work for this plane"

Not all speed controls will work on 4s Lipo, and the amperage rating has nothing to do with whether they will or not!

[pacro]

ok i just looked its made by align and it'll work fine so far with 3s's but what i'm trying to say will one 4s work for a double motor hookup
