Hobbywing 4465sl 44mm motor

thats right, they get hot easyly. I think the quality is slightly better then the pink kd motors, as the rotor is balanced.
if you need such a big motor and you're on a budget, go for the feigao 580l. it measueres about 44x74 mm, has an 5mm axle. it's not a lehner, but at least better then a kb45. some people are quite happy with the kb45, I think that their quality really varies from average to very poor.

the feigao has some cooling-holes, just put a nylon mesh over it to keep the motor free from stones, dirt.
