The OS 55AX does have a lot of grunt for a 2-stroke. It reminds me a lot of a 4-stroke (the way it pulls and runs) on my OMP Yak.

I have the same setup as Ernie and am very impressed with the 55ax. Pulls hard, throttles up quick and very very reliable. I found it on ebay NIB for $100 - so I had to try it, and very happy I did. Using Xoar 13x4 and OS F plug
