APC 13-4W to big for 55AX?
A friend is using the 55AX on his Great PLanes Reactor with a APC 13-4W with troubles of overheating. Is this prop really just too much load for that motor? An APC 13-6 with normal profile works well for the motor but not so well for 3D. Would the APC 12.25-3.75 be a better choice for a 3D propellor?
Thank You,

We've not run the engine with 3D in mind, so we don't have a specific propeller recommendation. However, run the engine close to 12,500 RPM and use a propeller that will fly the model how you like. Lower pitch is better for 3D-type flying.

I use both the 12.25x3.75 and the 13x4w on my 55ax fun fly type plane. I like the 13x4w for the outright pull. Engine run fine with it. The 12x3.75 seems to run to many RPMs. Go for it (13x4) you will like it.
