OS140RX Bearings

[vicenterc at comcast.net]

I think Ed is very lucky.  Probably, OS run out of standard bearings and they put an FI bearing in his motor.  It is evident that the common denominator is that you can not get more than 30-50 flights from the original bearing.  My OS 140 RX has more than 300 flights after replacing the original bearing with SS bearing.  Yes, I still run dry the motor and leave the piston in top dead center.

Vincente,

Ed's motor is NOT the FI..  I fly with him and it's true he just runs out the fuel after the last flight and no after run or anything.. motor still smooth...

Is your OS the FI version?  That could be te reason since that version comes already wint SS bearing.
