RE: Heli to fixed wing
For windy conditions, I would then go with the Acromaster. It is larger and heavier, and would handle the wind well. If you set up mild throws on any of these planes, they will fly well-mannered. I fly a 16 oz Airfoilz Yak from 3DX hobbies, and it handles the wind well. Being a heli pilot, you probably already have a good touch on the transmitter sticks, and won't over control. I have heard of gyros being used on fixed wing aircraft, but I have not tried it myself. I don't think you will have a problem handling one of these planes.
