RE: Is it hard to fly a Cub?
Much the same as my current Cub. GP 60 size with Saito twin 100. No extra heads though. Covered with Nelson RC Fabric. Also has floats, of course. Painted with Nelson paint. He has Lockhaven Yellow which is the true Cub Yellow. Great flyer.
Next Cub project waiting in the kit stack is a Sig 1/4 which will have a Saito 160 twin. Have floats for it also.
