I have a new MDS 1.48 engine, and was wondering what prop to use for break-in and then for flying.

I was thinking about an APC 15-8 for break-in and then a 16-8 for flying.

I'm flying at 5600' above sea level.
Thanks

Start with a 16/6 for regular running, a 16/8 is a pretty fast prop for the 1.48. For break in, try a prop that will not load up the engine, say something in the 4" pitch. See if you can find an 18/4 Zinger, cut it down to a 15 or 16/4, then balance it. Plan on running at least a gallon of fuel through this engine before you can start thinking it's broken in. DO NOT GET THIS ENGINE HOT DURING BREAK IN!!!!!
