"The ultimate engine for the Ultimate......that would be the ultimate Ultimate engine lol................is the Saito 100."

Now, does this engine vibrate less than the YS-110? If so then that's what I'll purchase. (I purchased the YS-110 from OMP as a package deal with the Fusion90, so I assumed it was a "match made in heaven".)

An autopsy of the Fusion90 showed that the balsa beams in the front 1/3 of the fuselage had simply fallen apart. Except for brief moments related to engine tuning the YS-110 never went over 1/2 throttle when mounted in the Fusion90. I flew the Fusion90 much like one would fly a pattern plane. Although my skills let me down regularly, my main flight thought is smoothness... with lots of loops, rolls inverted, etc. and with no "hanging from the prop". The YS-110 would "really shake" the Fusion90 when stopping, as "throttle down" was activated at the end of a flight.

My first wet powered toy (the OMP Hybrid Edge powered by Evolution 58) never showed signs of vibration wear. So I was very surprised by the failure of the Fusion90. I want the 10-300 to be more like the Hybrid than the Fusion90.

Thanks for your constructive suggestions, Glover.
