quark 125b

[Patrick]

Out of the 20 or so times I've ran my quark on 6s I haven't had any issues with it. Even with a battery straight off the charger it's never acted weird when first plugged in.

will i need a rcm heat sink on 12 cells ???????

I would. I have ran my Quark without it on 12 cells and it thermalled. That was using a 1930 lehner motor.

I have had my quark going on over a year. Got a heatsink, run it on 5s and 4s with no issues. You made a good choice. I would get the heatsink just to keep things in perspective.

I have one of the first Quark 125b's that came out. Never had to take it apart ever. Still going strong. The reverse brake, I've had that problem, so I jsut run my forward and brake. Never need reverse as I don't hit many things to need reverse and usually drive in areas that are open or can turn around in when bashing.

I think you will. From my experience a heatsink is pretty much needed on the quark in any 1/8 or MT application. Even if its not absolutely necessary it will for sure help keep you expensive ESC investment cooler and healthier.

i only askesd as i will have my esc before my heatsink will arive and i will want to use it lol so do you think i should run it untill i think it is too hot and then give it a rest to cool down?????? i wont be running long as i only have rubish 3300 oam cells so about 10 min run times so do you recon it will be fine for little while ?????????
thanks for your guys help so far it has been great

I dont think you will hurt anything by trying it out. Just pay attention to the esc temps and you should be fine. The best place to monitor the Quark temp is right where the motor wires come out of the esc.
