O.S. 1.4 RX bearings

[BUDDYonRC at aol.com]

I Just Changed the bearings in my YS-140L after two and one half seasons and 
about 1800 flight's only changed them because I needed to replace the piston 
ring and front shaft seal that was leaking, otherwise I may have run them 
longer. The YS cost's a little more but it doesn't require frequent bearing 
changes. and has adequate power for most pattern ships.
