Perhaps one thing should be added; a J-3 Cub is a great 3rd or 4th airplane, but not a good 2nd airplane, in my humble opinion. It would be better to gain experience with a tail dragger first, particularly one with a low wing loading (tendency to float). My observation is based on doing an 80" Cub as my second airplane, and the resultant crashes. Many airplanes later, I have finally added an 88" Clipped-wing 1/4-scale Cub to my hanger, powered with an OS FT-160 Gemini Twin.
