My name is Jose and I have an Extra 300 XS 1/4 scale powered with a Zenoah G62. My problem is that the vibrations of this engine are very high. I changed some propellers but I haven´t any solution. Please, can you help me?...
Thank you
Vibrations in Zenoah G62

Is the vibration at idle? If so, you probably have it too rich. They will really run rough if the idle needle is too rich. My G45 ran rough at idle until I leaned it out a bit.

Thank you John, that is true, but there are vibrations in my plane also in high rpms What can I do?

"Prop Balancing By Joe Wagner " quote "This is what Don Garry found he could take advantage of. By installing a purposely-out-of-balance prop on some of his engines, with the heavier blade pointing "down" while the crankpin was at TDC, Don obtained noticeably smoother running -- and enhanced performance! " the rest makes good reading and may solve your problem.
- Are you using a solid mount of a vibration damping mount such as those by J'Tec?

This is an old trick (heavy blad opposite the crankpin) that I learned back in the early sixties and used successfully since my control line days.
