So I've recently learned about ESC's, their function, and just how vulnerable/fragile they are. From people having blown ESC's from something as minor as a tipover, or a light crash against a small branch, I'm actually quite concerned about them. I have had a very minor crash with my Phantom 2 (non-vision), I clipped a branch and my phantom fell 2 feet into thick fluffy snow. All the props had stopped spinning, and I immediately turned the phantom off as soon as I could. It wasn't a big deal, apart from 2 cracked props. One of them was very hard to remove due to the force of the impact, but I removed and replaced it just fine. I have flown since, and have had zero issues flying, noticed no erratic behaviour. In fact, I didn't even know about blown ESC's until yesterday.
One thing I'm wondering is, if perhaps the extreme cold may have saved my ESC from overheating and blowing. It was about -25 to -30°c (around -13°F to -22°F) that day. But then again, I've read multiple accounts of people crashing all the time, tipovers, etc, without a single blown ESC, and others lost their ESC's while lightly grazing tall grass.
My question is, is there a way to test ESC's pre-flight to make sure they won't blow out on you mid-flight? I haven't opened up my shell yet to verify the integrity of the board. I will do that tonight, make sure the MOSFET's are in good shape, along with the soldering of the cables linking the motor.
Many thanks!
