OS 55AX
First off I haven't started this engine yet so my impressions are just out of the box. I've been into RC airplanes since 1981. Engine manufacturers have come and gone. My first two engines were a K&B .61 w/pump, great engine. The other was an OS Max .35 and another great engine. Both purchased in 1981 and OS is still building great engines. My new 55AX is much lighter than the .35 and is flawless in looks. Can't wait to put it in my Sig Kadet Senior Sport.Verified purchase: YesCondition: New
