    Question...
    Is is kosher to run the Phantom 3 without props. For instance if I wanted to drain a batt to 50% etc?

    Could it harm it in any way?

    No. The motor will be happy to spin without load. Just run it at low speed

    If you do it in auto take off they will start then stop

    I suggest a fan towards P3 to keep it cool.

    I read somewhere that spinning the motors without props for extended periods degrades the motor bearings.

    Where did you read that? I can understand that but part of me feel that if its idle then that would be the same or less stress then full throttle with props..
    But thats just me using common sense with out any technical knowledge of the engineering behind these motors; hence why I'm here and asked. :p

    Get a lightbulb battery discharger. They work great.

    Do you have a link to a suggested one?

    I've read somewhere that if you put it in a Phantom 4 it will discharge twice as fast.

    Sorry, I couldn't resist... I'll be quiet now. ;)

    A DJI moderator on the DJI forum wrote this post about the intelligent flight battery. DJI Forum|How do Intelligent Batteries Work?

    Here is that excerpt where it says not to.

    "There are two modes of discharging: the slow one and the rapid one.
    Slow discharging: Install the battery into the drone, turn the battery on and leave it electrostatically discharging until it automatically turns off when the battery level lower than 5%. ***It is recommended not to turn on the electric motor especially those without rotating propellers, as it may lead to abrasion of the motor.***
    Rapid discharging: Install the battery into the drone, fly it until low battery level alerts and the drone automatically lands. Do not turn it off and keep it discharging until it automatically shuts down.

    Wow, all this technical input. How about, it's ok to run motors without props for what ever reason. Only issue is putting wear on motors for no reason. If you just want to discharge the battery for whatever reason just turn on Phantom and wait until it's at 1 led. WTF Why in the F.. do you all make things so crazy???

    Hey Gunny, go drink a beer and relax. Both you and I know what they are saying, but this is the big time internet where there has to be rock stars! :p

    Just as a matter of interest, why do you need to do this. Isn't the normal auto discharge (set to 1 day) going to do the job?

    If you really need to discharge the battery, fire up the phantom with the props on and let it sit idling for about 15 minutes. That way, the props will be cooling as normal and the battery will run itself down.

    Me? I'd go out and fly it...
