RE: Flight stabilizers
The model is designed for retracts. Thus consideration of increasing tire size is out, for that would klobber the L.E. for the wing and cause other problems. I have not used the retract gear yet, because their position does not lend itself to controls yet. If I can get the A/C to survive a bit longer, they will be working, but for now, looks as if the model can only be flown by some Hot-shot. Which I am not.
