| Ok I have searched and asked but just need a bit more info. I am getting ready to buy my first 90, a Trex 700, and can't decide on the engine. OS has had their share of issues and so has YS. I am looking for the most reliable running and easiest to tune engine. If I get the YS I plan to use the MP5, if I get the OS I plan to try the new Align pipe. I have never flown a YS engine and have Hypers in my 50's. I can't find any specs on the YS for its power output. The OS:
