when i run 2 motors do they have to be the same? I'm new so that why i'm asking. Looking to run 1 esc with 2 motors.

JeremyH · 04-22-2009, 07:58 PM

Nope, plent of folks run different tooth pinions on their motors. I run different turn motors on my clod (55T front and 60T rear), however, I run dual ESCs, but that shouldnt make a difference.

PEDEcrawlerguy · 04-22-2009, 09:09 PM

as long as motors (when combined) arent beyond your ESC's motor limit.. i dont see prob.

ghostof1777 · 04-22-2009, 09:59 PM

So 2 55t motors would be fine? Also, is it better to run 2 esc or 1 esc? Any benefit w/ one or the other?

PEDEcrawlerguy · 04-22-2009, 10:03 PM

would you be running them in parallel? (positive off of esc to positive of each motor, same with negative) that would give you a motor equivalent to a 27t... as long as your esc can handle a 27t.... which most esc's should...

twitch1 · 04-22-2009, 10:29 PM

one benefit to 2 esc's is (if) you are running a stick radio, you have a lot more control over the 2 motors. You can run the rear, the front, or both whenever you need.....

ghostof1777 · 04-22-2009, 10:46 PM

Mamba Max esc would be fine?

Speedyboy · 04-22-2009, 11:01 PM

Yes thats perfect. (Actually overkill)

ghostof1777 · 04-22-2009, 11:05 PM

I like overkill

always have. Any advice on motors?

PEDEcrawlerguy · 04-22-2009, 11:16 PM

are you running adjustable motor mounts? if you are, i would try like 45t's, if you want a little more wheel speed, or if you like slow go with 55t..

what battery are you gonna run?

slow???? I can rock race with twin 55t's and 8t pinions. Of course 11.1v helps

I have seen allot of people run 1 esc with a 55t front and 45t rear to help combat stall. In all reality the only way to truely eliminate it is to run 3 esc's. 2 escs also give you control over both axles, this can be handy to get you out of a bind.

Currently I run 1 Mamba Maxx and 0 issues, soon to be 2 mamba Maxx's and 0 issues.

Sorry, how is the third ESC supposed to be used?

I don't know if it's common in the US, but here in Italy in relative-low-current applications such as crawlers (on even drifters) cheap chinese LiPos are becoming the rule.

You can actually find a couple of 4000mAh 15C LiPos for less than 25-30$, including shipping, on eBay if you purchase them from Hong Kong.

I personally run 4000mAh 15C batteries on my drifter and 3200mAh 25C on my scaler Bug and they work flawlessly

ghostof1777 · 04-26-2009, 09:05 PM

thanx carl

WolverineX · 05-01-2009, 05:28 AM

I used to run two Novak55's off one Mamba Max - stalling of the rear when trying to climb up something was a problem!
Now I got two Mamba Max ESC's a Castle BEC and a (DX6i) stick radio - it's like a new rig! Awesome! Highly recommended! I wish I'd gone for motors with stronger magnets though, the Integy 55t Lathe magnets seem to be stronger than the Novak55's. IMO.

chris_dishmon · 05-03-2009, 10:36 AM

even though you didn't say what kinda application you're running(2.2, super, rock racing, etc), i find my 35 turns with 9 tooth pinions to be a bit fast for my 2.2. it all depends on specifically what you're wanting to do.
