the extra 500 rpm's sounds good if not too expensive. I plan to run it next spring, just getting my ducks in a row right now. I have to finish the plane , to put it in.I started the plane about 15 years ago and plan to finish it this winter and install the OS 1.6 into it.

Its a Stenson Voyager and is the ideal plane for this engine. I was going to put it into a 120 size Zero I picked up , but the zero is not the easiest to fly and I am not putting that engine into a plane like that.

thanks, I'll put this in with all the info I get on it.
