I have an expensive paper weight collecting dust so if there is anyone who repairs esc's I would be interested as it cost me over £200 and only did one meeting for me before I sold it in perfect working order. The recipient soldered it into his car though and tried to use it only to find it faulty....
As a result I had to give a refund even though it was sold in working order, I can't be sure how or when it went wrong between me selling it and the purchaser installing it so I had to take it back in good faith.
Since then it has just sat in my house for the last 6 months, I can't bring myself to chuck it out but have no use for a faulty ESC either!
So if someone is able to repair them then that would be happy days!!
