I was thinking of buying a Hyde Mount HCMYS110A for a new plane. The plane is the Cermark Extra 260 and the engine will be the YS F110S.
I had this engine on a Showtime 90 and it shook the plane pretty bad. I wanted to install the Hyde mount to help protect the airframe.

After doing some research I am concerned that the Hyde Mount may allow the engine thrust angle to change. This would seem to be a problem during blipping the throttle. I don't think that have the engine jump around during a hover or harrier would be a good thing.

Is this a concern or should I not worry about it. Will I see a benefit with the Hyde Mount over a good composite plastic mount?
