sbd-5's first statement is by far the truth. Take me for instance. I bought a Nexstar trained on it for 2 months. Then i bought a GP P-38 (Built it in two weeks). I used OS .15 la's for power and I flew it once that year because I thought it flew to fast for me. After flying it this summer I now think it is way under powered. But it is all about how much experience you have and if you willing to build a aircraft and crash it on its maiden. Obviously try not to crash on the maiden. Really you got nothing to lose, except maybe a couple hundred bucks. But to me its about the experience. Did i mention I'm broke. Just kidding. Think of it this way twins are double the fun!
