According to Tony Bingelis, it is best to be "neutral balanced". Second best is to be "over balanced" ( weight heavier than control surface), and worst case is to be "under balanced" (control surface heavier than counter weight). As every KR is different in weight, size, and shape of control surfaces, what has or is working on one may not necessarily work on another. It is generally considered the responsibility of the engineer / designer to specify which surfaces need to be balanced. In our case the ailerons are the only surfaces specified to be balanced. You might recall that the pilot of one of the first WAR replica P-51's, which was based much on the design of the KR series, was killed when the aircraft experienced aileron flutter and crashed. You are your own test pilot. Larry Flesner
