wookong m reverse polarity protection?

[rwijnhov]

Ok just made the worst mistake of my life. I tried to connect my 4s lipo with reverse polarity to my flamewheel with wookong m. Needles to say magic smoke apeared. So far all my esc's seem broken. But the pmu is still giving me a green light. The led functions etc. So is has the wookong m some kind of reverse polarity protection so all my damage is the 4 escs. Or is likely to be all toast . No more beeping sound at startup also.

Some more analasys led on the channel cable in and out box is red. Led on the pmu is green. The big led is also functioning ok. In the dji assistent everything seems normal. So I am lucky and did i just frie my esc's?

Japp probably only your ESCs are gone ! PMU has a polarity protection. What about your RX did you check it ?

I was real lucky. Al it damaged was the plus trace on the groundplate where the battery ataches. After applying a big dap of solder on the trace and reconnecting the traces all is well again al esc's run great and the quad is flying again. So total damage till now one 5v regualtor wich powers my gopro and the plus trace on the groundplate. So it is looking good till now.
