Hey everyone. I just got a new MDS .15 pylon motor with the MDS tuned pipe. My questions: 1) What prop do I run with this motor? 2) Do I need to drill and tap the pipe for a pressure fitting? 3) Can I get different size spinners for it? Any advice on the engine or what airframes it would work in would be appreciated! Thanks.

I have no experience with this engine, but go to APCs' website and look up props in the 6.5x5 - 7x5 size range. Their website is tough for me to navigate, so what I do is make a list of sizes and call them to place the order.
Some .15s can be very picky about prop load and will benefit from narrowing and lightening the blades.

it should be able to turn an apc 7x4 -7x5 in the 18,000-19,000 range
