I need to drain down a couple of batteries. Is it safe to remove the props from the Phantom and just run the motors until the batteries drain. I was not sure if the props helped to keep the motors cool.
+1 ^ You'll drain more power faster with the props on. I've also heard that its not good to run the motors unloaded but I think that just means full throttle, anything below should be fine.
Yep, I'd keep the props on. Propless for short periods is fine, but I don't run down batteries that way. Heck, if it's going to be running the phantom, I'd just fly it.
I did it on my vision and the motors started stuttering and making a weird noise every now and then. I was told I was over revving the motors. I think they need a load on them.
