The reason I started this thread is that I am contemplating a scratch build for next season. I am leaning towards a biplane with a composite fuselage and foam surfaces. The plan at this point is to start the plug construction this weekend. Some features I am considering is a one peice bottom wing and plug in wings for the top. The top wing and stabs will have adjusters and the bottom wing will be set to .5 degree. Battery access will be a hatch just in front of the top wing. Still refining the outline.
