RE: HERE INFOS ABOUT OS 75 AX
Sucker. [sm=greedy.gif][sm=greedy.gif][sm=greedy.gif]
All kidding aside, I'll bet it works out fine for you. Probably won't have to drill anything, swap carbs, try 4 different pumps, and launch an internet poll to learn how to get it to run well either.
OS DOES love to specify large props don't they? Has anyone considered for a moment where these motors are made? Japan you say? Yeah. Japan is a real small, and densely populated island. Noise is a major issue, and large props are quieter in operation than small ones. An overly large prop may not show the engine at it's peak, but it will be quieter than a smaller prop turning a much higher rpm. Since everyone here is clearly better informed than OS on matters relating to glow engines, it is a simple matter of installing the prop which you find to work best for you. Problem solved hey?
Have fun with that "odd sized" .75.
