Hey guys, I've had a 5.5T 60A EZrun combo inmy drift car for a while now, and it started playing up- power and steering cutting in and out. Then, I pull it up to check it out, turn it off and then back on again, and *pop*- a puff of smoke emerges from the capacitor set. i cut the heat shrink away and find the earth sided capacitor is fried, as is this tiny little rectangluar box in front of it. Has anyone else had this problem, and can it be fixed without replacing the ESC, if so what parts do I need to fix it?

Cheers

Conrad
P.S I'll post pics of it after work tonight...

i did. Just de-solder the caps, replace 'em. Or you can run without them. It happened to me when I accident;y reversed the batt's polarity.

Hello. I have a problem whereby my 5.5T motor eventually slowed down and stopped. My battery was still ok. The ESC responds to the throttle because the red LED on it flashes, but no turn on the motor. Also no beep produced by the ESC.

Any ideas please???

I am having the exact same problem as Hitz1980. Ran for 2 minutes, died, lights come on when they shoud but beeping stopped. Checked esc on another motor, same problem. Run 2s 7.4 lipo 5000mah in good condition. Cut off set at 3.0v per cell.

Any advice would be great.

Thank you

If esc does the same thing with another motor that you know works good, the esc is bad. If its new, its warranty time, time to return it and get replacement.

Thanks for the reply, was just living in hope that, that wasn't the problem.

Hi Mick,

I reported back to the chinese seller on ebay the problem I have and was advised by him that the ESC had died. Fortunately the chinese supplier was happy enough to post me out a new one free of charge so hopefully should arrive next week. He advise it was a faulty unit sent out but not sure about this now as you seem to have the same issue.

By the way anyone, what burst and timing setting should the 60A ESC set to for a 1/10 on road car. Not sure now if the battery I purchased could cope with the default settings of the ESC and decided to fry??? My battery is from Hong Kong, a 7.4V 5200mAh 2S lipo with 35C and 60C burst and thought it would be good enough to cope with the power. It was quite cheap compared to most other branded ones. Please advise. Thanks

Not sure on the settings you need to run, but I would stick to the defaults or whatever is recommended in the manual. As far as the lipo is concerned, the cheaper ones like that can be widly overrated. If the C Rating is accurate, you should have no prob with it. Run it a few minutes with a range of throttle input and check the lipo temp. It should be barely warm. If it's hot, the C rating is optimistic and its going to have issues supplying the current the motor needs. Prob need a better lipo in that case.

Not all cheap lipos are like this. The HobbyKing lipos have been around and seem to be long past their construction issues/cell probs. They've been tested and proven to be good for the price.

Thanks for that.
