I did a maiden of a 210mm quad today. During a short punch-out burst it just stopped and fell to the ground and I'm wondering what the cause could have been. I'm quite new to the hobby and it's not always clear to me how to diagnose situations.
parts:
- 1806 2300kv motors
- KingKong 12A BlHeli Opto ESC's with dampened-light
- 50x40x2 props
- Afroflight Naze32 rev6 flight controller
- LemonRX DSMX compatible receiver
- Turnigy nano-tech 1300mAh 3S 45~90C Lipo
I did the first flight on a 2S lipo and all went nicely. Then I switched to a 3S, did a few easy fly-by and of course got greedy and punched it a bit. The thrust of the punch surprised me so I quickly throttled down, which made the quad begin to topple over as it started falling down. I then pushed the throttle up again but the quad didn't react at all, commencing to crash into the ground. I turned it off the quad at that point and haven't turned it on again before I have some more info.
Doing a sniffing test, I can smell that the rear two ESCs have more of a burned smell than the front two, with one of the rear ESCs being a bit worse than the other. It's unclear to me if this is an indication that they're fried or not. I don't see any black marks on them. What would you advise is a sane and safe way to test them? I'm also curious what and ESC behaves like when it burns out or starts to get overheated. Does this cause the quad to cease all action? Or would it all of a sudden send the quad into a crazy spin? The motors weren't hot, by the way.
Is it possible that the LemonRX receiver had a brown-out?
On a side note, the FPV video transmitter also burned out but if I had to guess (correct me if I'm wrong) I don't think that that has anything to do with the above. The impact cracked the antenna off of transmitter and I suspect that this caused the FPV video transmitter to burn. If I'm not mistaken the antenna acts as a resistor to the transmitter and if you remove it the transmitter can fry itself, is that correct?
Thanks in advance!
