FED50H
Threw this hideous edf together... Just a looooong morning of failed attempts. I moved the CG around, added tape and weight....still enjoyed being out playing around even though no flights were achieved. This thing would not break, and I wanted it too...3 layers of green crappy foam, 3m spray adhesives together....

An option to try. I ended up with 3 degrees upthrust and 1 degree to the right. Try that. Start with forward CG.

It should fly.
I like to design and fly unique planes.

Also all the weight is on top of the plane. So once it starts to pitch, it wants to pitch even faster. And i think youre right on the chord being too short. Best of luck on the rebuild

The control surfaces are too small, so they are hidden behind an airfoil that thick.
Because of this, when you pull up, you kill the lift.
I'm not so sure the CG is off, you need to fix the control problem first.

Build a little compartment for the battery on the bottom of the plane.
I'm not sure it is a must have, but this will improve the stability.
This will also give you more freedom of placement so you can get the CG right.

I'm pretty positive it was extremely tail heavy. Try moving the battery way forward next time.


If you were inside your plane... You would never crash.

Yeah that's uber tail heavy.

Another thing is these flying wings are EXTREMELY CG sensitive since the plane is so short. It's gotta be way nose heavy to fly well.

I had moved the CG all over the place, added more of a front fuse and moved the battery even more forward. At one point it was very nose heavy, and top heavy. I think the thrust angle was a huge issue as well. I had threw it together to test the strength of the green foam as well. It surprised me. I appreciate all the advice. On to the next one.....
