Patriot Retracts - Mechanical or Pneumatic?
My 50 is an older vintage 50FSR, not the newer SX. I just bought a new OS 32SX for my Modeltech Extra 300. I'm going to break it in this weekend, but if the props listed in the manual are for real, the SX is a much stronger engine than the OS 32F it is replacing. Are the OS manuals optimistic?
