Boeing 777 EDF Delta Airliner

Boeing 777-200LR • Scratch Build EDF 

This project was a 2 year concept, it took an unfinished prototype and many hours of work to get to what you see in the video. This plane is inspired by DemonDriver, Ramy RC and Ethan Potherings airliner builds, it is not as perfect as theirs but it still looks SWEET in the air :) 

This is a card model based on this paper craft: http://cp.c-ij.com/en/contents/CNT-0011813/index.html

It is made of white dollar tree foam, depron, Canon craft paper (yea, actually, its good stuff lol) and brown Flite Test foam for the wings.   

And some pictures of the build process

Please excuse the lego :)

Successful maiden, I know these pictures are no good, but they do the job.Before this I had never flown an EDF jet in my life so I had no clue what to expect, but this beast performed excellent.

Phresh paint :D and time for Flite Fest




It was terrifying flying this plane at Flite Fest, but it can down in one piece, (sort of) and did everything I needed it to, so I cant complain. The crash at the end resulted in the retirement of the plane.

The best way to describe how it flew would be scale and smooth. From a distance it looked super scale but it could still pick up speed for a low pass. This plane likes to fly fast when it can. It doesn’t stall very well as you can see in the video, it nearly stalled in that first takeoff. And of course, a stall caused the crash.

The EDF’s are in a package from Grayson Hobby, with speed controllers and servos included. http://graysonhobby.com/64mm-edf-flight-pack.html

They are powered by a common 3S 1300mAh battery for about 3.5 minutes of flight time.. 

This is a four channel hand launch, so no landing gear or flaps, because they are too heavy for this 51 inch long plane. 

It has a split elevator, each controlled by its own 9 gram servo.

Soon I will build a much bigger airliner with landing gear and flaps with a nice fiberglass job.

Thanks to Jackson and Cole for the videos, and to everyone else who cheered me on while flying this beast. 

I learned A LOT from this build, I encourage you to build your own plane like this if you haven’t already!

Great article! I saw you repairing this plane in the build tent and it looked awesome! Nice job. Build another and make some new memories. :)

Thanks James! Another one (this time with landing gear to remove the sketch factor of hand launching) is coming very soon!

Thanks Tim. Truth be told I don’t have the money either, the electronics were a birthday present :D

That looked like the common EDF problem to me, not enough thrust. The angle of attack was steep and not enogh speed so control was not good. The advantage that a prop has is that it blows air across the control surfaces.

Before this I had never flown an EDF in my life, so I had no clue what to expect. Multiple EDF pilots have told me it takes awhile for these aircraft to accelerate, which is quite accurate in my experience. Only the launch was a challenge because the aircraft was at the edge of a stall and accelerated slowly to get up to its cruise speed As the pilot, this aircraft flew amazing and was very controllable.

i made 737 with two 55mm edf ended up too heavy, i used to design it papercraft plans too, i have two edf 55m they give about 800g thrust , they should give about 1kg but because i have unhealthy 30c lipo battery it doesnt give enough amps to the edfs. also i have few small problems with my wing design ( i built mine full with dollar tree foam board) please can you share with me your plans

I’m happy you like it, unfortunately I can’t give you plans for my RC model, but the paper model plans that I used on this website for free http://cp.c-ij.com/en/contents/CNT-0011813/index.html they are very good and only took a little bit of changing. If you can make that sweet ATR you can make this. now I need to get to work and build your ATR, a great looking plane! :D if you have more questions I will do my best to help.

It was nice to see paper and foam model Boeing 777 flying. Your model is inspiring one. And there is lot to learn from it and from you. I have made two models of Boeing 777, one is Boeing 777 300ER and other is Boeing 777LR. These are Card sheet models and planing to make them electric with ED fans. I would have sent pictures of them but there is no provision in comment box.
Wishing all success to your future plans

That’s really cool!! I’d love to see your own 777, it is my favorite plane, and thank you for the kind words!

Dear Kieran W, Thanks for your reply to my comments. Please suggest as to how upload or send pictures of my Air India Boeing 777 ER and LR models to you. I couldn't find your email ID for communication on this site.
Thanks.
