I am flying a super cub with numerous STC's , Vortex generators, tundra tires (31") belly pod, and constant speed prop. I want to do a full stall series in the aircraft including accelerated stalls from a 45-60 degree bank and am concerned about the stall characteristic's . On a full power departure stall I run out of right rudder just before the break. Have checked the rudder and it 30 degrees per type certification. Has anyone with the same mod's spun their aircraft. What happens with a cross control stall.
