thats completely different to the one i have, its 3/4" the length of the motor, has 1mm clearence between the motor and the inside of the cooler

i've ordered a new typhoon 500H motor from HK, its the 2200kv which will go in my cat on 4s, will give me 32k rpm's, should bring the amp draw down a bit and run cooler, just got to wait for it to arrive now, may even buy the 600H and stick it in the 29" mono
