28 size 4 pole motors?

I didn't mention Neu as they are a bit oversize, 1.14" is 29mm, which may pesent mounting issues, I have a car which mounts down a tunnel and it would be a hell of a job to fit a motor just 1mm bigger, very good motors though if it will fit.

While more powerful for sure the 1112 and 1115 are much bigger motors, the 1112 is the equivalent of the 16/30/x and the 1115 is the 16/40/x. If the Mega 1515/2or3 is suitable for the application the equivalent Neu would be 1105/4to6D at .25 ounces lighter or 11071.5-2Y at .65 ounces heavier.
