I would think the havoc esc would run it without issues, but may not run it as well as other choices... but if you got it, run it. Don't know how many amps the havoc is, may not put out as much power as other choices, or maybe it does if it's at least a 120a esc. But should not have problems (opinion of novac aside). Dont run timing on the 4 pole motors.

My last motor was a tekin sc4x 4800kv motor that was labeled as 4.5 turn.
