Quark Monster 125 w/ Lehner 1950/6?
 

Hey everyone just wanted to see if my Quark Monster Pro 125B ESC will handle a Lehner 1950/6 Hi-Amp motor on 4S lipo's? BTW, it's going in a savvy.

Yes, it will. For extra caution use the RC-Monster Quark heatsink with a fan and you're off to go.

I think I've heard a few ppl using that combo, I have no idea how it performs though. I wonder what kind of current that thing can suck?

Yeah, for 4S it should be fine. Just get good cells.

Gear it for about 35 mph and you have got a solid setup.

Just for grins, what would I need to get into the 40mph range?

Other gearing. the setup can do 40mph with ease.
