Just registered yesterday 11-7-13 so am way behind on this thread but enjoyed it immensely. Ken are you still fabbing away on the RM Bipe? Your engineering skills are impressive. I built 2 planes last year without a board and wound up with a warped outboard wing on my bigger plane. It's a modified Viking - put flaps on it and changed the rudder. Bould a modified Vampire with rounded tips like the Shoestring. The geometry came out good on it. Made a wingboard for 2 home designs and got them straight. Built a large combat wing for fun and it works too. Rebuilt a RM. a Shoestring. Flite Streak. Combat Cat while messing with the first two. Finally got color on all the planes but haven't fully completed any. Getting close. Want to see that RM of yours with some cover and color. WC
