Jack,

I don't think my 320 has any counterweights, pendulous or otherwise - I= t=20 just keeps driving forward, except when it wants to stop rotating every so m= uch=20 of a revolution. It may be presumed that the Landoll damper is not=20 removing high order tortionals, but it does mediate the negative torques per= =20 your web site discussion. How much? Who knows? So far, you are t= he=20 only one that has offered up any information for consideration. N= one=20 on the airfoil, just the info on vibration. I think the damper is far=20= more=20 effective (torque wise) on a constant speed prop than many would give=20 it credit.
