14 poles and 920Kv.  This motor does very well on the 11 x 5.5 or 11 x 4.5P APC props on 4S.  We are currently flying a Pathfinder and Brodak Profile Hellcat with it on 4S 2800's to 4S 3300's.

Hi John,

I've used many of the E-Max 2820's (same as Arrowind) and I battle to warm them up........not complaining! Cool is good. Maybe your motor is getting hot on the static run and the air is not not getting through the motor. So just check to make sure that you have a good airflow through it. The motor structure allows a nice flow of air, so it should be fine in the air. What model do you have it in?
