Yes, the MK mounts are so called soft mounts, but the vibration damping characteristics are real bad compared to
the Hyde mount. Real bad .... I have a MK mount in one of my planes and the servo current consumption is more than
twice that of a similar plane / similar engine with Hyde mount. And yes, this is with a super smooth running OS160 not a
four stroke. I wouldn't use the MK mount again even if a saved a lot of time during building...

The time I saved using the MK mount, is about half of what I will spend rebuilding the nose and installing a Hyde mount....
