I am curious to know if a mamba monster on A123 9.9 volts would turn two cobalts smoothly? Parallel wiring. Zero to step by step smooth. Not sure if thats a MM question or a Cobalt question. Either way, any input would be helpful.

The little cobalt 500 is pretty powerful, but it is hard to compare to the 540 body motors. They feel about the same, but I haven't been able to dyno one to see just how it stacks up.

Yes it would, no problem at all. Even a MM would do the job.

Very cool. Thanks for the info. Running 2, 7 turns would equal running 1 3.5 turn? Is that correct?

Yes, but these aren't like a normal 7t. They are about as fast as a 30t motor.

John,

I have four 2S Lipo's that I don't really want to replace, they a rated for 24.2amps continuous. I'd Like to run the 7T. My question is this: Is there any reason I shouldn't just run 2 of the Lipo's in parallel?

That should give me 48.4 amps continuous with double the capacity at 7.4 volts and I wouldn't have to replace my batteries.

I managed to score a NEW 5t off a forum member a while back, and I'm now debating what vehicle it will find a home in.

My question, is as to how is will handle a 3S LiPo. Is this fine, or will the motor be running a bit hot?

I think running two packs in parallel is a great idea. I have done it before.

It would run hot on 3s, but for comps it is fine. Just don't go out bashing for too long without keeping an eye on the temps- keep check on it until it stabilizes and you know how hard it can be thrashed.

John, rigtht now i am running a pro integy lathe 65 turn motor. i love the current speed i have with it. not a real fast kinda guy. my problem is i would like more torque. i was going to start a new thread but the forum woudnt let me. i want to know what motor you offer that will give me pretty much the same speed, around a walking speed along with monster torque. i had gotten the rig all bound up a couple of times this weekend at a comp and it didnt have enough torque to break things or to get me out of the bind. not saying i want the torque so i can brake things but i would like to have a chance to get out of binds if need be. running a sidewinder esc, 3c lipo, bec and so on. any recomendations? thanks in advance.

I have more on the way, should be about two to three weeks until they are back from the machinist.

I don't have anything so slow, except another 65t motor. The puller would be more than twice as fast. I do have one 65t Torquemaster, which will give you a lot more torque with the same wheelspeed. http://holmeshobbies.com/product.php...&cat=17&page=1

is there a way i could run the 7t and put a big big spur gear on? i really dont mind having wheel speed but i am more of a torque guy. how well does this motor run at crawling speeds?

The puller runs very well at crawling speeds. Gear it down as much as you can, maybe run 2s lipo or equivelent, and you would be just fine.
