ESC Repair

       Remove this ad - become a site supporter!
I have obtained 2 HV-Maxx speed controllers with a Novak 4400kv brushless moter.

The problem is that both of the ESC's are shorted out. Novak called it a dead short. Most likely a blown cap.

Anyone good at testing and repairing ESC's?

I doubt you will find anybody other than the factory qualified to do it. Heck I have training as an electronics technologist and I wouldn't take it on.

Reasons why:

1. Lack of circuit description/theory of operation and schematic diagram.

2. High level of miniaturization. You are down to needing a hot air system for soldering and desoldering these tiny surface mount components. I bet most of the time it is cheaper for Novak to replace versus repair due to the work and risk involved to achieve a sucessful repair.

3. Proprietary components. Many key parts will be either branded just for Novak or made special for them. So if you need a part you are screwed.

Good luck just the same,

ESC repair

I know a guy. He's fixed a couple of mine and modded others for more performance. He's in the US so it takes a little time but he's reasonable and does great work. PM me for his info if you want.
