Windraider A380 sail plane electric conversion?

[neu]

Hey guys,

I'm curious if anybody made EDF conversion of this Windraider A380 sail plane?

I've seen one with two props, but I'd be interested to see something that looks more scale like. 2 or 4 EDF I mean. I'd like to know if it's possible to make it strong enough to take offs, and optionally to install retracts, and maybe flaps :)..okay the last two thing is maybe too far, but for the EDF and take off by keeping the scale look, I'd be seriously interested!

You might post in the Foamy EDF forum, there have been some discussion there since its inception.

Well, this is the place you propse :) At least I didn't find other Foamy EDFs forum.

I think you have a cool idea! What livery are you going to paint it in?
Now,you are trying to tote the weight of retracts, and fly, but not 100 MPH here right? Why do you think flaps are so far out? I think it is a good goal.
HL sells Fowler hinges for a Fowler looking flap. Might consider scale spoilers, as you may have greater need of those, which HL also sells.
Airx, you have been doing this longer than some (or most) wouldn't it be in the cards for a pair/quad of six blade fans at maybe 100% FSA? I am not suggesting a diffuser, however he needs ounces, not airspeed.
I normally never suggest GWS, or brushed, but quad configuration, twin brushed esc, two per side, one ESC per side, and possible mix with the rudder on a pair of 3s2100? Don't order, think about it, and lets see if the experts agree. Your talking 40 ounces here of thrust here max (10x4), and good service life provided you stay out of the wide open throttle thing most of the time. Would an EDF 75 look scale on this baby? :cool:

Sorry it took so long, been snooping around. Check out www.e-fliterc.com.
They have a super airliner and the fans/nacelles seem farely inexpensive. Got a 3500 KV outrunner too.
Landing gear with sptingloaded strut caught my attention for a different project-I actually ordered the nose gear from my LHS this morning!
Anyhow, the fan and nacelle is designed for a near identical application, and isn't breaking the bank, like some models, has a nacelle available, and a motormatch. Might be worth a shot

[AirX]

The naccelles were designed arround the GWS EDF55's, just use a good bl in them of maybe 4200kv and your gonna get enough thrust to fly. The larger fans wont look scale but will work.

What I saw wasn't a GWS product.. It was A 3 blade fan made by Eflite.

Skonworkstexas,

I think we are talking about two different airplanes and it is not a GWS product either, the one Nue is looking at is the one from Hong Kong of the Airbuss 380 with 4 fans, the Eflight is a model of the Boeing 777 with 2 fans.

Check out these threads...

Yes, we're talking about two. I'm talking about the windraider glider (same as the one on the links), and he's talking about the E-flight airliner, but for an example I think. I think he meant that the same config would be good for the A380 too (probably doubled)

But did anyone tried any EDF solutions?

I've just checked the nacelles on the model looks a bit undersized, and different in shape. Maybe a bit larger then 55 fan would be still good with custom build nacelles (which would be necessary anyway, as it was designed for decoration, not for power). What is the next available size? Probably a 65mm one would be still okay if there's any appropriate ones. What BL engines would be good in size? I assume we're talking about 4 motors, 4 esc, and 4 batteries? Probably there would be solutions which provides enough thrust, but the plane probably would be too have, and landing speed would be too high. That's why it came to my mind that probably fowler flaps would help a bit if it's possible to install somehow.

However for this conversion lot of things needs to be reinforced to make it reliable and durable. That's why I'd like to see a working solution :)

Eric, I know he has something different than the Eflite. I thought he was looking for motor/Fan combinations? I found a simular product that its PARTS can be purchased with the motor/fan/nacelle from one vendor, that had a product, of simular size that works. Just helping out where I can....... ;)

[AirX]

Its cool, if you look in the links I posted there is reference the GWS conversions.

I was reading all the topics concerning this conversion, I've seen one with EDF installed (GWS if I recall right), but I've never heard if it's working or now. I've seen the prop conversion working, but this one is not in my interest, as the scale look is important for me.

HI

A few are working on EDF conversions I have seen.

Some with Props, GWS EDF's and myself using wemotec Micro fans. I am all in for scale looks and have added wing spars to handle the heavier airframe with full working retracts (all 22 wheels), knuckle hinged surfaces and flaps. I will be covering it, so you won't see a foam airplane.

Hopefully I will be finished in a month ready for summer flying (I only get 30 minutes a night to work on it - work is very busy).

I have one of the Windrider A-380 foamies as well.....

I recently got a couple of these preconverted 130 watt Brushless EDF-55 units with EP2030-4400KV motors from Epyaya:

http://www.epyaya.com/product_info.php?cPath=225_226_308&products_id=1007

On a 1000 mAh Common Sense 3S pack it showed 138-140 watts right off the charger. Not bad for 40 bucks for the preassembled fan with a brushless motor already in it.

4 of these gives a bit over 500 watts, which would give decent airliner performance at 5 pounds. I bet it will be a little heavier than that, with decent landing gear.

I don't like the looks of the too-small stock nacelles on the foamie A-380, either. You can tell it was done mostly for slope soaring as a glider, with electrification a secondary priority....:)

The new Eflite airliner nacelles actually look closer to correct shape for the Airbus.

Thank for the response! I'm looking forward to see your birds flying! I see you want to do the same things like I want! Do you have a topic for your project? I'd be glad to see some images! Especially ones that related for the conversion like retracts, nacelles, flaps etc.

Did you guys reenforced the nacelle pylon?

I'm wondering what is the size of the E-flite airliners nacelle. I've found the A-380 small too.

Hi

Yes, I reinforced the Pylon with Light ply. I sliced the pylon in 6 squares and made an interlocking lite ply structure. The nacelle is glued to the pylon - but the pylon will just be plastic bolted to the wing to allow it to rip backwards if the landing gear fails. Then maybe it will get some replacement better units!

The Nacelles are small- but this isn't a 100% scale kit so I am not going to waste time in changing. I want it to become a sport plane I fly at Club events.

Retract wheel units adds 250 gms - I went this heavy to ensure they handle the 2.5kg expected flying weight - and poor quality landing sites!

Neu, sounds like good feedback! The EDF that CorsairNut in a different thread ran gave 12 ounces at 4000 feet with the Eflite motor-Might be more like 14 at lesser altitudes and temp! Like, 56 ounces of thrust! Thats cooking! :cool:

[neu]

Brenton,

Well if it will fly with any EDFs that fit in this nacelle, it's fine! I just thoguht if the 5mm EDF is not enough, maybe it can be still scale like with a bit bigger one. What power system ou have for your bird exactly?

I love your retracts, I can't wait to see them operational! I'm curious how do you install the bays! ;)

Skonkworkstexas

which thread is it exactly? I'd like to see the details!

It is the F20 EDF build thread in this foamy section. CorsairNut is the one trying a 6 blade wattage, cut down to three, making it identical th the eFLITE

See the landing gear we made:

These LGs are awesome! Thanks for posting! Would be nice to get these in a pack ;)
