Maybe the wing is to large. Trimming it down will reduce drag.

Not enough washout at the wing tips. Looks like you might have a problem with tip stalling. Try landing a little hotter.......

The heffershaft is missaligned. Delta G is building up on the LE of the tri-stabilitor causing and inductance of monohydrox on the bathinon pinion.

The easy fix...

...paint it green.

I think a nice Hacker B50 and a 4s4p lipo pack swinging a 15x8 prop should make it fly. But it might be a bit marginal with the power.

Ps it plywood?? Not strong enough, try oak.
