Hacker E-3 motor question

This is a pretty basic question. I have a Hacker E-3 3700kv 280 motor, with a 2mm shaft. What is it good in? It'd probably run onn 4s. I was thinking a smaller onroad or similar.
Edit: I think I'll use it in a Sportwerks Recoil if it isn't too big for the motor. Here's a review:
