Default i think i killed my HPI apache C1 speed control, please help

so the controller is made to run 2 7.4v batteries, i had 2 5300 65C packs. i then went ahead and installed a 14.8v 5500 60C and i ran the car for good 30-40 minutes till the battery died. I then let the battery cool off and charged it up. next day i tried to run the car and it would only twitch, i then tried again later and saw a little spark at one of the speed controller connectors, any ideas as to why this happened and if in fat i did fry the controller, what should i look for in a new one in order to run my 14.8v safely and not burn it out.

Reading what HPI says your 4c pack aka 14.8 volts should be fine with that esc.. No way of knowing how you cooked it, it happens. You may have just got a bad one.

Call or email HPI and see if they'll replace it,, good luck

Product Description
== Key Features ==

* Can handle twin 2S LiPo batteries
* 4mm bullet connectors
* 13-gauge wires
* Integrated cooling fan
* Easily connects to your computer for total programming control

== Overview ==

The Flux Q-Base Brushless ESC is one-half of the Flux Brushless system that is fitted as standard equipment in the Savage Flux 2350 truck, forming an unstoppable power force for amazing off-road power!

With the ability to handle twin 2S LiPo batteries (that's 14.8 volts of LiPo power!) it can deal with anything the Alphastar 2350 motor can dish out! 4mm bullet connectors secure the motor wires for loss-free connection to the 13-gauge wires, and to connect to each battery pack we've attached real Deans® connectors for zero power loss and total efficiency. We figured why re-invent the wheel and release our own connector when the best is already available?

Topping off the versatility of the Flux Q-base is an integrated cooling fan, which allows the electronic speed control to operate at its ideal temperature.

You also have the ability to easily connect it to your computer for total programming control! With our HPI100573(sold seperate) USB Programming Kit you can connect the Q-base to any Windows-based PC to control all the various facets of its power delivery, braking, throttle curves, battery cut-off and much more. You can also save various profiles to have profiles for racing, insane speed runs, stunts, fun running and more.

With the Flux Alphastar 2350 and Q-base combo, you get power optimized for 4S LiPo batteries, with custom tuning thrown in for fun! You'll have to experience it to believe it!

Huum,,,
Looks like the switch melted too,, you running that car in tall grass???
You make just have over heated it and the solder joints melted,, I'm surprised that doesn't have thermal shut off.

you going to try to fix it or send the pics to HPI?

I'd rather solder on short leads, than solder those connectors back on. Also seems like they would always be asking to break off. I wouldn't be surprised if they were cold joints to begin with. I would imagine mechanical shock caused them to fail, as they would have to be very poor solder connections to fail by melting, but who knows.

The switch makes me think over heating, but that could have happened if the battery shorted too,, Lucky the whole thing didn't go up in a lipferno

well nothing melted, thats just the sticky foam ripped off that was holding the switch in place. im debating if i should try to solder back or maybe even just take to my local RC place and let them do it, not sure yet, prob cost me $5-$10

LOl, Well then Bill might have hit it,, just the vibration or it's a defect,, either way I'd ask HPI to replace it if it broke or it burned up under the normal rated use

good luck

I did that to an esc last week, combination of heat and landing over and over on the lid on a track (oops) and im sure a suck solder job from the factory. My neighbor soldered them back on the board and it works fine. Had him do it because he has a much nicer digital temp selection iron and way better skillz for getting onto pcbs. Runs fine is the point
