I agree the dihedral is off. I don't know for sure but doubt it is an electric vs glow thing. I also increased the wing incidence a little. Except for the down line mix and rudder aileron mix there is very little other coupling. The vertical and knfe edges in this design are affected fairly obviously by CG changes. I ended up with a CG to give me the best vertical (with a slight increase in wing incidence) and the knife edge flight is real close. The only odd trait I found is the lack for need of much expo on aileron and elevator. I believe the counter balances are causing this. On the other hand the rudder is extremely sensitive and I have my expo dialed way up on it. First flights were interesting with 40% expo on ail and elevator.
