Re: cyclo polisher

Did this polisher work out for the Nuvite? Does the recommended 3M 05711 pads work well with it? For me it worked great with nuvite. I used the cheapie harbor freight pads rather than the recommended pad, and was happy with the results. I am sure it would work with the recommended pads as long as y...

Re: What is the fatigue life of a Sonex?

John, With this setup the travel of the throttle cable at the pilot's controls is very small. Is that how yours is? Any issu...
