more than enough power.
I run 1512/2.5D 2000kv on 5S lipo in my quite heavy maxx. motor stays cool and it will flip anytime if i am not careful with throttle.

How do you have that maxx geared Wallot? I've always liked the 1512 as a cheaper option to the 1515, yet its still much more powerful than a HvMaxx is.
