LRP speed controller - smoke + melt = broken?

[Rocksteadyeddie]

I bought my son a LRP S10 Blast BX 2.4Ghz for Christmas. Charged the battery and it worked straight out the box. Then recharged the battery and all seemed well. A minute later the car started going backwards despite the RC unit being turned off. He picked it up and a few seconds later smoke starts pouring from a part with a heat sink on top which I believe is a speed controller. I turned everything off as quickly as I could, unplugged the battery and let it cool down. The result seems to be that everything turns back on ok, the car steers but there is no motion forward or backwards.

Does this mean its fooked?

And a secondary question if I may... Why would it do this in the first place?

Thanks in advance

The part with the heatsink is the speed controller and if that's where the smoke was coming from it sounds like its had it.
It's either been connected to the battery the wrong way (assuming the connectors allow this), shorted out on the motor outputs or the unit could have been faulty too start with.
Just leave the battery disconnected and take it back to where you got it.

Obviously someone had to show him how it works!

Yes it is knackered but the bit I've highlighted is relevant, the Transmitter is always switched on FIRST & then the battery connected & the Receiver switched on & vice versa when shutting down. This may have caused some of the problem.

Ok thanks.

Contact the place you bought it. Some LRP ESCs are notorious for this BUT their support is very good (if a little slow sometimes). Failing any sort of support from the supplier go via LRP but as it was sold RTR you should have no problems getting it replaced.

I intend to do exactly that. Of course they are not open until Weds so post back and forth and he won't get it going again until the New Year.

Interesting... Santa also gave my little boy an S10 Blast. It has been cutting out and finally, my boy steered it into a bunch of Agapanthas... Got stuck. I asked my boy to go and pick it up but he didn't. Then I heard the wheels spinning and told him to take his finger off the trigger. "its not on the trigger" he said. I went over, smelt plastic burning, picked it up (wheels turning), took the body off to find the esc smoking. I switched it off and then disconnected the battery. Looks like a similar problem, if not the same. I also have an HPI Bullet. We have been using both heaps over the past few days. Neither have been modified and both used in the same sort of environment. No problems with the bullet. I too will take it back to see what can be done, but any further advice will be appreciated.

Sounds the same problem we had. The speed controller is fried. The shop we bought it from asked that we return it for an exchange so I have bought another one in the meantime.
