align 91H replace rear bearing with boca enk-003
120 flights on my Align 91H in my T-rex700 and my rear bearing is failing.

I have the Boca MR16003 replacement kit ENK-003. I thought I read somewhere that the steel race or retainer can rust and damage the engine. Should I just use the stock OS bearings or are these ok?

Thanks
IT's what I do.

You can use the either bearing. The cage will rust, but if you are going to fly a lot this summer i would not worry about it. Just don't let fuel sit in the motor for too long.

About the only thing impressive about Boca bearings is the price. If you haven't already bought them try http://www.rc-bearings.comAndy
