John, I pulled my Jumping Bean out recently and I felt the same thing about it. My father built the plane in the late sixties and it sat around since then. Upon inspection I noticed a few things like elevator surfaces being over controlled, wing warps, and cg issues. Of course I flew it first before really inspecting it. It was a handful to say the least. I believe most of us figured that more elevator was always better utilizing the furthest hole out on the bellcrank. This was the case in my Jumping Bean. This really helped calm mine down. to where I could control it without over controlling it. I used foam wheels where the original woodies that came with the kit probably would've made for a better balance point. After a few mods and some extensive heat gun work on the wings, the plane was really flying well. One problem I can't fix is that the trailing edge is glue on in a downward position on the outboard side which is causing the wing to fly tip high. I've twisted the wing to compensate, but I really want to fix that problem. The Ambroid its glued together with shouldn't be too hard to break free. I have three 1/2a's that are my fav. The Baby Tomahawk, Jumping Bean, and the Baby Flite Streak. Ken
