Hi,
I have a Dynamic WT9 plane with a Rotax 912 100 hp with 166 hrs, I flew the plane and suddenly the engine started to vibrate worst and worst every time.
I did all the things that friends told me that can be the cause, I know very well this carburators because they are used in the BMW motorcycles so I did a complete check and changed the diaphragms and did the syncronization using a two bar mercury instrument, I changed the spark plugs, checked all the rubers and hoses, I built a special bench rig to balance the propeller to 0.1 gram at the tip of the blade, I set the pitch of the blades with a laser at 20 mts to be super acurate, I did everything and the engine vibrates a lot.
My propeller is a Woodcomp three blade constant speed in flight ajustable, I changed the propeller with a Bolly Magna carbón fiber super light ground adjustable propeller perfect balanced too and the engine vibrates very bad too.
Some friends told me that the problem is in the gearbox, but an engine with only 166 hrs can have a damaged gearbox?
In case it is the gearbox how can be solved?
Regards from Mexico!
