Multiplex Acro Master Vibration Problem?
Hello fellow E flyers,
My Acro Master flew perfectly for about 90 flights. This is a great plane and fun to fly. I now fly it more often than I fly my large planes. But it now has a problem.
After the 90 flights it went from very quiet to a loud vibration sound. ..... I checked the prop, replaced the motor, tightened all (37? ;-) mounting screws (per the factory). The last seemed to help a lot. ...... BUT the plane still makes a small vibration sound.
A flying buddy said he saw on one of the forums (ezone.com, but I was unable to find this site?) that someone posted that the plane needs another brace on the motor mount and a foam block up front to solve this problem after the 1st 50 to 100 flights.
Does anyone know about this fix ????? ..... TIA for your help.
Regards,
