DJI motors run time.

If battery was not an issue, and you could sustain power to the motors.. what would be the deciding factor how long a flight should be.

what is the running temp environment for the standard 30amp Opto and the 2212/920KV motors?

Each will be different... Payload, camera, FPV or just ARTF for fun?

Without FPV gear and a 2250mAh Pulse 45C pack I can safely fly for 9 minutes while doing line of site slow flying

@ DesJardins,

thanks for the info.. but I was wondering if Power was not an issue. I was looking at temp or ESC or Motors would be the next. Reason I ask, is that I read someone users are flying 30+ minutes.. granted, maybe they have enough C ratings to keep the motors running cool, but I was wondering if Power was not an issue. . let say, "dreaming" of 50,000 mah.... would the motors or ESC be able to keep up the constant endurance of a single long flight?

Regards,

KS

You pose an interesting question. The answer is actually easy to determine. Take a machine with the Naza GPS, remove the flight battery and attach a 50' extension cord connected to a 50 Amp DC power supply which should put out about 13 to 14 volts. Pick the machine up to say, 25' with position hold engaged and wait to see what happens. If the machine starts to loose power, it will descend, putting some of the weight of the extension cord on the ground, making the ship lighter. If a bit of wind comes up, making the rotor system more efficient, it might try to climb and thus pick up more of the weight of the cord. It would certainly determine the limiting factor of the machines endurance. Sounds like a fun experiment.
