I have an older Quadra Q35 that seems to vibrate excessivly which I gather
was fairly common with early versions. I have heard that they can be
improved by adjusting the flywheel balance. Has anyone done this? How much
weight did you add/remove and where? I would assume that one would need to
add weight dimetricly opposite to the crank pin.
Any suggestions welcome.
Thanks -Rob-

Also balanced by prop weight - refer to Giant scale Tech Tips =
Don Garry, of Cocoa, Florida -- used deliberately UNbalanced propellers to
enhance the performance of some of his engines.

My Q35 performs well using above technique.

A lot of other tips available under "Giant Scale & Large RC models"
