Capgains,
Thanks for the shared info. By the way, I can not help but notice the Spacewalker in your small pic by your name. What model MFG is it, and what engine set up do you have for powering the plane? I'm looking for the right engine for a GP SpaceWalker 1/4 scale ARF. I'm thinking the YS 1.10 would be a winner if I can get the settings right. I'm actually wanting to overpower the plane to the point of unlimited verticle, but do not want to stick such a heavy 4-banger on it that if flies like a rock. Is this possible, or will I have to resort to a 2-stroke for the performance, weight ratio I'm wanting ?
