Thank you for that information about how to beef up the wing. In regard to the radio all I have is to ready to fly controllers that came with ready to fly kits. One is for a horizon hobby sport Cub s and the other is for a wltoys f949. I don't have any working receivers but I was thinking of getting one for the f949 because it has the relays I mean the servals built into it and it doesn't have Auto stabilization so I think that means it can be installed at any angle without affecting the flight
