[NSRCA-discussion] Bargain on OS 140RX stainless rear bearings

[Chris Moon]

I have a 140RX motor w/ over 350 flights w/ the EFI bearing and the 
seals not removed.  I also replace the stock bearing on a new motor 
before I even fly it because you will be right back in there in 50 
flights or so to replace the stock bearing anyways.
Nice catch on finding them at other than Tower!  I'm going to get a 
couple for future projects.
