The better plane? That depends on what you will use for the motor and what flying you want to do. The Extra needs a little more power than the Cap to have the same power to weight. The Cap does better 3D type flying due to the design differences. The Extra is a very good pattern type platform. I flew the Extra with a gas motor, the BME 50 is incredible. A friend flys the Cap with a Saito 1.80, wich need expensive 30% to have incredible power. His also weigs alot less and lands better. If you put a Moki 2.10 in the Extra, I think performance will go up quite a bit but then, EXPENSIVE GLOW FUEL AND LOTS OF IT.
