RCBearings OS high speed two stroke rc engine bearings offer dependable, long lasting smoothness.  These have as good or better performance than what came standard in your engine at a fraction of the cost of OEM bearings! These have a high speed plastic retainer from Japan in the rear bearing.

NOTE:  These rc bearings are appropriate for Heli engines. All heli engines .40ci and above should use a rear bearing with a high speed plastic retainer!  Beware of other sellers that try to pass off cheap standard bearings with metallic retainers for your expensive heli engine!
