I am just about to start building a 50 Caliber designed by Dick Sarpolous. I am wondering if anyone would be interested in a build thread? I have my engines ready, and have started the engine nacelles. This will be my first twin, so comments, suggestions would be welcome. I will be using 2 OS .25 FX engines. The wing will be a foam core, sheeted with 1mm poplar. I am going to vacuum bag the wing, and fiberglass the entire airframe. I will also be converting this aircraft to a tail dragger as it is a practice plane for a larger WW2 twin warbird.
