I have an Impact with OS140RX. Being used to flying four-stroke YS140's , I find throttle management much more demanding with the 2-stroke( otherwise an excellent engine). I simply like flying four strokes.....

I have a YS140 DZ that I am thinking of swapping in for the OS. My concern is about vibrations. The Impact is extremely stiff and probably doesn't dampen strong vibrations very well. The vibration level with the OS and Hyde mount is acceptable.

Does anyone have experience with vibration levels and DZ's / Hyde mount in the Impact ?
