RE: Piper Cub Question
I had this model and it is very easy to fly. The ground handling can leave a lot to be desired since it has a tendency to ground loop, but with the low take-off speed you only have to keep it in a straight line for a little while. Plan to either set differential in the ailerons or mix in some rudder. It is very prone to yawing with aileron application. With the sole exception of take-off, it flies very much like a trainer. In fact, it's a little slower than most trainers on the market.
I've flown mine with everything from an Enya .25 BB to an OS .15 LA to a .40 4-stroke. The Enya was a little too much power. A .25 LA or .30 4-stroke would be ideal. This plane should be well within your capabilities.
