Ok, I know that engine vibration should not be present if properly tuned and balanced prop is used. But I am talking about high frequency vibrations that Ineed to get out of my airframe.

Heres the question. Is there a way of using a rubber isolation layer between the engine and the mount to reduce vibration from going through the entire airframe.

Here is the problem: The plane I built is as pictured below and at full throttle Iam getting my throttle servo and aleron servos to jitter a bit. At half throttle it goes away. I was thinking it is a high vibration frequency thing. Is there any suggestions out there for solving this problem?

thanks.

I seem to have had some success with the use of automobile engine gasket material - perhaps 10% - 15% reduction in vibration.

In the photo the engine is connected to the carriage by two 3mm steel plates. I put small sheets of gasket material in between these. The material has a light green surface and shows white where it has been cut.

Hope this helps.
