Hi sportrider_fz6
Cubs sure are a fun plane to fly. Do it wrong and they will bite you. My current cub is a 71" wing span SPAD with an OS 46FX engine and a 12X4 APC prop. Early on it snapped rolled on me on take-off, cart-wheeled, and ended up-side-down. Being made of Coroplast there was no damage except the prop. Coroplast is a tough material. Most people believe it is a standard kit or ARF plane.
