Got a quick chance to check Jer's Bipie out at lunch today... Excellent design & mods. Minimal adverse yaw with just the bottom ailerons, and acceptable roll rate. The tail-biting loops are a blast!
The wind was ~10mph, so we had to fly it further from us than would make sense to video (no zoom on the cheap CVS camcorder), so we'll wait for a calm day.
All-in-all, it's the right size and weight for the CDR motor. Crazy throws help as well. The Parachute landings are cool
