All Right. Y'all. I did not mean to start a debate. MY Ringmaster has five additional rib bays and hardwood spars top and bottom with front of the wings sheeted for strength and rib caps and T.E. caps to smoot everything out. Some extra tweaking, but I build all my planes pretty much this way. I could care less if it is LEGAL by standards I don't go by. This plane, overpowered and all turns the tightest turns I have personally seen except by a full combat voodoo. I have never considered the wing popping off. I am not interested in flying a pattern set forth by unknowns in unknown areas. I fly my own set of patterns trying each time to bobble less and establish a good low base line to enter and exit from and to generally be sharp and consistant. The newly modified Chipmuck was rebuilt to rid it of the inability to turn a radius bigger than Dallas. Oh, sure, it looks cool and steady and makes beautiful take offs and landings, but if I was to do a simple loop I had better gain a LOT of altitude. NOW it zips around ALMOST as good as the (modified) Ringmaster. I fly it. I love it. I am not competing with it. I do have a slight problem with the quick vertical engine hesitation, but am reluctant to seek further advice on this forum... I do not believe my brother and I are the only ones left in America that really really really enjoys flying the way we do. It only seems like the natural progression from the little .049 to .61. Bigger, faster, more powerful, more manueverable and more trustworthy. AND we also use an electric starter for the sake of convenience and ease, and an extendo stick to keep our fingers from the prop while tuning. ANYWAY, I do appreciate any help I get, even though I don't belong to any elite group. Thanks FRED
