A friend purchased a flying early 320 and soon remarked to me about how squirrely it flew. I told him that my 235 didn't have any of the bad characteristics he was describing. When we examined the CG in our individual airplanes we found his CG was much further aft than mine in my 235. He added a nine pound dampener to the end of the crank and that moved the CG forward and the aircraft flew much better, but he still was not happy with its flying characteristics. As I recall fairly early in the 320 production Lancair started offering an extended engine mount and longer cowl to address the CG problem.
