nice replacement bearings for OS37
Posted by Unknown on 19th Jan 2015
I am fairly new to nitro, and when my OS37 stopped working one day I opened it to discover that the rear bearing was rusted. I had not been using after run oil because the manufacturer of the nitro fuel claimed that it was not necessary. I was glad to find these replacement bearings for a low price at RCBearings.com. Paul was very helpful and gave me tips regarding the bearing replacement procedure and prevention of rust. So far, these bearings are performing well. They are much cheaper than the stock bearings. The 30 size nitro helis are very rare nowadays, and I am glad that RCBearings still carries these replacement bearings for the OS37 engine.
