Hi Netters, I followed the balancing discussion for some time now, and to through some more fuel into the fire (or to just post a dumb question): Shouldn't the Ailerons balance each other, since if the left one goes down the right one goes up? I personally do not recall that we used balancing weights on the gliders we build at the glider group in Germany.
There was only one reason to add counterweights to ailerons, and that was to increase inertia of the system as to reduce Eigen-Frequency of the whole system to a manageable frequency. Schleicher Aircraft used an interesing method in the ASW-19, by putting lead into the top of the control stick. You may forgive me if the self balancing of the ailerons is not possible with the KR-2, as I am not yet fully familiar with the control mechanics. I got my plans only a few weeks ago and still in the study phase. Wolfgang
