Pete- please tell me what rpm this engine turns a 13-8 prop, both on the ground and in the air? I see that the website says it will handle a 13-8 so I figure you must have some data to base this on, and I would like to know this because I'm thinking of putting this engine in my 40 size mustang.

For those who really care -
the prop reading on the ground is TOTALLY independant from in the air readings .
The max power in the air is NOT the same as the max torque available .
The maximum torque available with no muffler and or a muffler or a pipe is again not the same in any of those cases
The best prop for a given type model is a case by case thing -involving the engine- prop and plane and the manner in which it is flown.
When asking about how well the engine will work for YOU- -it is necessary to include all this info.
In the case of the 13x8-on this engine - it would likely be best on a light model which was not intended to be a fast flyer.
The smaller props which allow the engine to run faster are better matched to it - for most sport applications.
