Thanks for the advice everyone......Well it looks like I'll hold off on building the bipe, I didn't realize the flight characteristics might be so different (high drag etc.) I'll make it my 3rd plane. I'm leaning either toward the Venture 60, or one of the Spad's, based on your recommendations. Also by the way, GrnBrt I forgot to post the mid-wing (was tired when I posted) It is the SIG something extra kit. Although since I have a .46 engine already, I'm leaning toward the .60 size, and the SIG runs the .40 range engine. Again Thanks..
