Strengths:
delivers loads of turbine smooth power. . . .
Weaknesses:
none. . . .
Overall:
At risk of starting an arguement I think for 2 strokes you can't beat OS. Does make a big dent in the wallet though. . .

Strengths:
OS 55 AX really very powerful for an engine this size, will swing quite a large prop if required, usually starts by hand first flick when run-in. . . .
Weaknesses:
Expensive. Haven't tested the crash-resistance. . .
Overall:
Needs running-in properly, but once run-it it's a nice little engine. . . .

Strengths:
very light, very powerful, not to expensive. . . .
Weaknesses:
body is made of very very thin lightweight metal, smashes to pieces at the slightest crash. . . .
Overall:
Well worth the money, for performance, reliability and power especially as a 46 size upgrade. Just do not hit the ground hard. . .
