I'm working on a Big lazy Bee with the 72" wing. I like the looks of the plane, sort of a cartoon caricature of an airplane. Got the wingtips, elevators and rudder laminated, and the center section of the wing built so far. I'm using the big 6" trexler main wheels, and a trexler tailwheel. OS .40 FP for power, Sig Koverall and dope for finish. I don't know about the CG on the smaller ones, but on the big bee, its about a half inch forward of the main spar. I've had this kit laying around for years, and finally decided I needed another floater for nice calm days. 2-11/16 inch tall shear webs, wow! Also I'm not going to use the rubber band mounted wing. I'll use the bolt on wing method, but with one #8 nylon screw instead of the two 1/4 inch ones suggested. I''ll probably use the same type of mounting for the removeable tail, with #4 nylon bolts instead of rubber bands.
