Afro 30 or Afro 20 slim

[miniconverter]

Not sure whether to use the Afro 30 or the slim 20 on my build. Like the idea of the slim 20 as they fit in the arms but am concerned about cooling.

I';ve got the slims ... there is no heat spreader on these and I have to say they actually get warm even when out in the propwash the way I';m using them ... conversely the 30A ones I have from http://multicopter.gr/ are literally air temp after running 3 batteries through them and a not especially gentle way ... but really the answer will depend on the current draw of the motor / prop combo and how much headroom you have in the capability of the ESC.

Also,  remember that the slims will require any external BEC to power your electronics. There isn';t one built in.

Decided on the 30s so went to order non in stock so any other recommendations. I liked the idea of the Afros as they came ready to go with the simonk firmware installed.
