Both the Learjet 25 and the AC-47 I flew in Viet Nam had free floating ailerons. The control wheel was connected by cables to aileron trim tabs. The controls were very effective. But that is the reason that the Lear was limited to 0.80 Mach--aileron buzz was quite spectacular above the Mach limit.
Of course, the aileron trim tabs on my AC-47 were about the size of the elevators on a KR. With the near-neutral stability of a KR, the effectiveness of the trim tab is small on a properly functioning elevator. But, it is the difference between continuously correcting the aircraft attitude and getting a few seconds to do other things in the cockpit. Jim Vance va...@claflinwildcats.com
