RE: OS 46/55 bearings bad again!
I've run Super Tigers, TT Pro's and OS's. I fly several times a week and have never lost a bearing other than a seal on the front bearing of a TT 61 pro. I've have used several brands of fuel, but always make sure they contain Castor. In my opion the most reliable engines for power, smooth idle, and dependable transition low speed to high are the OS's. I started with the Super Tigers because of price, but know I,m happy to pay the premium for the OS fx's and AX's because it saves me a ton of time and money not having to replace planes or make repairs due too flame outs. I live in dry climate and corrosion is not a problem. When I use an after run oil I and hate to admit it use being a diehart GM guy use Ford ATF it has the same properties of the high dollar after run oils on the market
