Feigao Bearing Upgrade?
 

http://www.offshoreelectrics.com/MainPage.htm

Anyone tried the bearings bout 2/3 the way down the ''motors and mounts'' page right after the feigao motors? Its supposed to be an upgrade bearing for the Feigao motors. I have an older Feigao 540 motor that I feel like the bearings are starting to get rough and I d rather just repalce them cuz the ones it comes with are supposed to be cruddy anyway.

Are these a worth while upgrade for a 540C-XL? even if it running fine?

Would a bearing upgrade help increase the effiency of the motor enough to make any real difereance in the heat it generates?

If the bearings are failing, then they can affect efficiency. If the bearings are fine, then upgrading them won't affect performance.

I've heard of problems with the bearings failing and causing the motor to go bad and the esc as well.
