Can thoses large electric motors, Hacker B50 and C50, AXI 4130,etc. continuesly run for 1 or 2 hours? If not, what motor can do this? Thanks.

Sure,
As long as you have proper cooling for the motor, the motor isn't being pushed past what it should, running for extended periods of time isn't a problem. Oh, you need a high capacity battery.

I guess your trying for an endurance record or something?

Hi! Bill:

I was told by Hacker Brushless USA that the maximum time is 30 minutes for C50. I know that some electric plane can fly 2 -3 hours ( not those crossing Atlantic ocean). They might use different type motor.
Do you think It will be OK to run a significantly extended period of time if the motor is exposed to the air (not in the plane) and the plane fly at 2/3 - 1/2 throat at most time during flying?
I am not trying an endurance record. I just need a longer time to take aerial image.

I had never heard of any time limit on the Hacker.

I have a C50 Acro 12Xl, but I have never run it longer than 12 minutes.
I can only assume that Hacker USA is recommending this conservative time for applications pushing the limits with high heat build up.

I'd call them back and see if they would clarify the 30 min max time.
I don't know of or see any reason it would cause any problem as long as the motor and control are properly cooled.

Actually, enclosing the motor with a carefully-planned cooling duct will help keep it cooler than being out in the open air.

I'd like to know about a 30 minute electric flight setup also.
