H520 motor failure after main board replacement

[RPG]

I bought a H520 main board from John several months ago. One motor was erratic and went into 5 motor mode after lift off. The logs was just a few seconds so not much to go on. Carol did contact me the other day to my surprise and e talked tonight and she said Mr. Carr wanted me to post the issue. She has a mess to deal with and hope it works out for her. If any one has a clue I would appreciate input
Thanks

Have you swapped the problem arm with one of the other arms to confirm the issue is with the board and not with the arm?

No. This was a H Plus that was new. I needed to map and didn't know that it couldn't be set up for that. (Miss information ) I can give it a try.

I have now swapped the arms and the same motor does not power up. After stopping it beeps a SOS .

Do you mean the new motor in the same position as the original problem, or the same motor when in the new position?

The new motor failed in that position. The motor that previously did not work,started as normal.

Sounds like a failed board. The capacitors and mosfets sometimes fail. The older models with stand-alone ESCs had a controller on each, and those controllers were the main failure. Not sure if the one-piece boards have individual controllers or not.
At this point you can either look for a replacement board, try to find a shop that can figure out and repair the board you have or see if @Carolee-GF Yuneec Skins has another in stock.

I have one on the way, do you know of a shop that could repair boards. Looks like we are on our own. I noticed the UK dealer is no longer repairing. Makes me wonder what the future holds for Yuneec.Thanks for the help.

"do you know of a shop that could repair boards."
None. A really good computer shop might, but I doubt any of the drone repair shops ever got to that level of repair. It was cheaper to replace than to repair at that level.

"Makes me wonder what the future holds for Yuneec"
As a company? Pretty much nothing.
As a legacy brand, it will be mostly eBay, Amazon, the Forum. and self repair for at least the short term.
