Will a neu motor work with a mm esc ?

It will if you can gear low enough where it doesn't cogg. Even then, that's still too close to the "cogg-threshold" for my liking. You can help this by increasing start power and throttle control.

Besides the 2.5d is 1700kv if I'm not mistaken. Running at 4s (the MM max), that's only ~25krpm. To get any speed, you'd need to gear higher, which is pretty much opposite from you want to do.

I would suggest getting a higher kv Neu motor shooting for ~40k rpm @ 14.8v (kv between 2500 and 2700) and gear down.
