Finally finished my buggy conversion!!! - RC-Monster Forums

I had a quick read & it's saying that the ESC is 25A & the motor can draw 45A, that's not comparative though.

My ESC's can all cope with more amps than the motors can draw, so, where does that leave CC's theory/explanation?

ok, when u fire it up tomorrow, run at very low speed (barely moving, without cogging etc) for a few minutes. then take some temps. do it on grass if you can :)

the motor will be (SHOULD) be cool as well as the lipos. the ESC however will be warm. (harder to see on a V1 as the fan is ALWAYS running...) then do some top speed running (after everything is at ambient) and check again...

the motor should be warmer the lipos warm and the esc cool. it seems almost like a resistor, burning off the ecess current off but i know it doesnt work like that (i.e manual speed controls!!!) so how it works exactly im not sure... could it be to do with the variable timing that the escs use? *or is that only castle ones??*

id like to know too. hope this helps :)

btw, where do you live? im in brissy and if you were too (hobby garage is a name i am familiar with!) we could possibly meet up once youve got it all sorted to compare etc..

It sucks that you burned up that quark. I was waiting for someone to do a review of using it in a 1/8. Based on the motor, voltage and gearing I don't blame the quark for failing. I think you would have burned up just about any esc with that setup. I still have hopes for the SSB being a viable 1/8 controller and based on the specs and the success of the predecessor the 125B I still expect that it should be a nice controller for 1/8, but they are virtually impossible to get here in the US at this point and it seems rather expensive everywhere else in the world.

If you are planning to run it on the track with 5s, the 1600kv Medusa motor you linked to would your best choice of the motors mentioned. the 8xl will still run hot for extended runs.

Nice conversion. Hope you have better luck with the next setup.
