Interesting how difficult some cubs are. My second plane was an eflite 25 cub. It was my first big plane at 60" wingspan
That cub has never given me any trouble and flys great. Everything I hoped for flying a cub. Slow flights, gentle moves, flat turns, and great looks. Ground handling is fine if I stay on the rudder early. But I fly off of grass and have heard it is easier. I take off on low rates and then switch to high rates for loops and rolls. Two important parts of my set up is differential ailerons and balancing it so the wing is level instead of the fuselage. The fuselage can throw you off.
