Very nice looking Spitfire and glad to here is fly's well om a 20cc engine. I just finished mine today and I hope to maiden her next weekend. I did not have a 20cc engine but I did have the EME-35 that is the same weight as the DLE-30 I had to add 4 oz of weigh to the nose the get the plane to balance. I am using a Xoar 18x10 prop that should provided plenty of speed. Here are a few pics
