I'm running 1800kv's with a max draw of 16.6a each with 20a esc's.

1.2/1.5 x 16.6 = 19.92/24.90

Not sure if this is good for my esc's but I have had no issues with lack of power, or heat.
This is all great information guys! It's snowing like all get-out right now so no flying today but if there's time later tonight I'll see if I can get the 45C battery contacts soldered up and give it a ride tomorrow. It's funny, I was dreaming about the Armattan last night. I was flying over a busy highway and got stuck flying too low across the lanes and had to weave through traffic. I managed to avoid the cars but crashed into a parking lot on the other side. I busted 2 arms, lost the KK2 board,couldn't find the battery and all the props were trashed. It was the kind of nightmare where you wake up in a cold sweat.
