Newbie looking for advice. I am stuck with an edf and do not know which plane to build.

[akimbo]

I made the mistake of purchasing an edf instead of a prop to build my first plane. I have made several planes using a 50 mm edf, most of them lack a proper airfoil and are quite fragile. I got lucky with my first flight but I soon realized that having a highspeed plane is not very ideal. Does any one know of a plane that can perform better at low speeds and uses a 50mm edf? I have found some planes that would be suitable but they do not have any plans. I'm sure someone will tell me to search the forums and the flite test page but, I promise you that is exactly what I have been doing.

Try this plan for the 50mm.

DIY 50mm EDF Grunjet

Introducing the Grunjet, a two sheet foamboard performance jet flying fast and sporty, slows down to a crawl on landings, and is packed with amazing vertical performance, all only costing $80 to build! With this plane you have the option of building the plane with a V tail or a standard tail...

the grunjet was a lil too fast for me, do you know of anything that has an airfoil shaped wing?

 

[speedy7385]

Have you check out the L-39...50mm edf also with airfoil.

Plane - L-39 50mm EDF

This is a fast, fun flying 50mm EDF jet! It's a basic build without a ton of parts, it's got a basic control setup of throttle, elevator, and ailerons to keep things simple. Just build one already :D Speed- Top speed is great and slows down very...

I think you may be trying to fit a square peg into a round hole. EDF planes are fast - that’s just how EDFs work (creating thrust from a small cross sectional area of air moving fast, where a prop moves a bigger area more slowly to create thrust). It will always be a challenge for a first plane so you will need some determination. I’m not sure changing the wing shape will give you what you’re looking for. I’ve never flown a grunjet but it has a good reputation - are you flying at high throttle? Maybe persevere with that model but try slowing down and see if it’s stable enough at low speed for you to keep up with it better?

The grunjet was pretty good but the wing was not very durable and in the few times I flew it the front half of the plane broke off when I “landed”. Currently I am building a trainer style plane that should be more stable and easier to fly at low speeds. It is my own design so I am not sure if it will fly. I might post some updates tomorrow.

I haven't built this design but it seems to be an easy first jet to fly

AP Eazy Ducted Fan (50mm EDF Trainer)

STATUS: The maiden flight was successfully completed and the BETA-plan is published! The AP Eazy Ducted Fan is a EDF Trainer that works with every 50mm EDF unit. Once in the air, it is a breeze to fly, it is responsive but without any vices and the landings are easy. Look for yourself...

Its basically a Tiny Trainer with an EDF

I watched your video again. Here are some thoughts. The foldover KF Grunjet wing is pretty durable. I've built the wing but not the plane. Its going to be difficult to get a more durable wing. For your first flights you did really well - why don't you repair it and see how slow you can go. Immediately after launch and getting some altitude throttle it back - go slow. A bigger field would help too. Paint one or both wing tip red on top of the wing to help orientation. Paint the tail red too. If you're a beginner pilot learning on your own this is how it goes - build, crash, repair repeat. Don't get too attached to your latest build. If you can find an experienced pilot to help you trim that plane that would help a lot. Stay on the simulator as it looks like it helped a lot.

Thanks a lot for the advice guys, I think I might go back to the grunjet eventually but, for now I am going to try to fly this plane until it breaks.

The glide test worked pretty well. It’s ugly but I think it will fly

The Jetworks site has a free plan for an EDF trainer.
