As many of the others have said 200 hundred flights does not seem like a lot of flights to me. I don't understand why the engine should ever shake the plane apart if everything is kept balanced. On the soft mount. The profiles I have soft mounted I used lords mounts and acouple of aluminum plates. It really will cut vibration, but the problem of the plane tearing itself apart at idle I am not sure you can do much for it.
On my well mounted and secured YS-110, I've only run APC 16x4W props that were both blade and hub balanced.
On the vibration issue, I've done some more online reading today about two cycle engines and think that I might wonder on down to the local hobby store and get them to order an OS 120AX for the 10-300. And escomposites even has a pipe for it. This could be fun! Now to the experts amoung us (or even the opinionated, as my motto is: "Frequently wrong, never in doubt!") should I get a "pump" (whatever that is, as my research is not yet complete)?
Fly safe, Glover
