FYI, a full-scale Piper J3 Cub does not have flaps, typically uses a 65 hp Continental engine, uses a wooden prop, and the pilot sits in the back seat. A full Scale Piper PA-18 SuperCub has flaps, which are very effective, typically has a 150 hp Lycoming engine, has a metal prop, and the pilot sits in the front seat.

Also, the full scale J3 does not have an electrical system. So no lights, no radio (other than hand-held), and the engine is started by "proping" - turning it through by hand.

The PA-18 is a real STOL workhorse aircraft. It is popular for towing gliders, short field operation, float operation, etc. It is rated as "utility" by the FAA, which is just below aerobatic.
