Well, today i was out driven(stampede), just running on an 8 cell Ballistic 2400 pack, crusin along, then it died, and i was feeling crazy, so i strapped in 2 6 cell packs(with custom parallel connector) so i was gunna do a 12 cell speed run. I set it down in the grass, and goosed the throttle, then let off. the trigger was at neutral, but the truck was at full out, i quickly turned off the transmitter, and it stopped, so i reset the controller, and picked it up this time, and hit it to half throttle. It stuck there. Then i turned off the transmitter, and for some reason then it went to full throttle, ripping the glue off my freshly glued Mahser 2ks. Then after a few seconds, it turned off again.

Im not sure why it does this. It does fine on 6-8 cells(havnt tried 10)
It is a Kontronik 12 cell fwd only controller. I have no clue why it is doing this, but one of these days its gunna take off down the road at 50 mph and slam into a house or car or somthin, damaging what it hits, and im sure destroying the front end of my pede.

Does anyone know why it would be doing this? Maybe on 12 cells the BEC malfuncions and that freezes up the controller? I dont know. But it didnt do that on any of my other 12 cells runs.(only did it twice prior to)

Also i checked some of the "Duh, why didnt i think of that" things, like low transmitter batts, bad reciever connections, ect...

The radio is just a cheapy Futaba Magnum Sport AM, but i dont think that is the problem.

Any help would be appreciated.


Also, how do i bypass the BEC on my contoller, what wires need to be cut?

Thanks for any help

Peace,
Jordan

Uhh, thanks :D

I figured it out though, i just forgot to put the screws back in that keep the can from popping, and it popped a little ways which caused it to stick at the throttle position that it orignally recieved from the controller :p

Simple enough...

Top speed with a Garmin GPS so far on 12 cells and 15/87 gearing is 55.6 mph...
Now a guy from the traxxas is running the same motor as me, cept his is the C40, and on 12 cells hes gearing it anywhere from 18/87 up to 22/87, and considering i have more torque than he does, i think i could gear even higher. So i should break the 60 barrier. Swami(the guy with the c40) already hit 59.7 mph, (shown by a Garmin GPS also)
So the 60 barrier isnt un realistic at all :D , the only thing is finding the room for it. Luckily i got the perks of being able to use the runway out at the local airport(at which i am a pilot) so i got a strait just over a mile long to play with(obviosly i dont have that much range though) :D

Fun times!

Yeah, its a C50 on 12 cells, its got some POWER... :D

It didnt literally throw the tires off the rims, but it tore the glue, and i had to reglue both rear tires...
