My original FC board fried the power chips so I replaced the whole FC with a different board and the same thing happened the two power chips fried. I might also add that I also was getting voltage critically low immediately and I also bought two brand new batteries and threw away the old ones...
I'm interested if you still have it. I have one but the flight control board burned up so if you give me a good price and will ship it to me in California. Let me know. My email is [email protected]
