Will it harm anything because this set up running parallel is sweet. Can I leave it?

Wont hurt a thing.

John, I just got my 7T puller installed in my TXT with a GD600 running 85:1 reduction and a 6 cell pack. WOW :shocked: this motor is nice! Can't wait to see it on 8 or 10 cells when I get the new packs built. I have a 10T preordered in case the 7T isn't happy pushing around a 12-15lb truck.

Thanks again for the awesome motors!!

That should be enough reduction to keep it pretty happy. Just make sure you use stout cells to keep up with the amp draw requirements. Otherwise the packs will wear fast and the performance could suffer.

Right now I am running Intellect 4200 maH sub-c batteries right now.

Just put a few up on the site of the 5, 7, and 10t versions. The 10t is indeed faster than a 35t handwound 540, just did some testing to confirm this.

Basically even the 10t is faster and more powerful than any other crawling motor!

did i already miss out again on the 10t pullers? site shows them out of stock :-(

Yes, the 10t version is gone until the next production run. The 7t will be available for a bit longer.

do you have an ETA for the 10t's? I think a 7t might be too much speed after watching that video for the 10t on your site, haha i might kill myself if it goes any faster :lol:

You could always just use a lower voltage, like 6 cells nimh or 2 cell lipo. Heck, even 4 or 5 cells would work. It could be a year or more before the next production run, and when that happens the prices will go up. The inventory I am selling is actually a few years old so the cost of manufacturing was lower and the $$ was stronger.

Just reread the thread and saw that these were limited and you were trying to bring them back, that's pretty cool.
The 7t's also show out of stock but if you have one I'd like to relieve you of it's burden, and a 6 cell 1500mah saddle pack. Was going to send you a pm but I think it's broke ;-)

Are these colbalt motors the ones that have that distinct whining sound? Not complaining about the sound, just wondering. :) If not which one is that? I saw a few rigs at the last comp with that noisy motor, but they had great low speed and nice wheel speed.

Cheers,

Rob

Just installed a 7T into my WK Widow. This thing kicks _______ <---enter any expletive :lol:

And just in case you're still doubting or don't believe what has already been said about these motors, I'll do the math for you....

6 pound 2.2 rig + HH Cobalt Puller 7T + Delrin 48p spur gear mated with steel pinion gear + 9 cell Elite pack + Mamba Max + grippy Losi Claws + heavy throttle finger = weak link goes bye bye

I have never stripped a spur gear in any electric car I have owned, including some brushless one's...so this definitely surprised me. Time to switch back to 32 pitch gears and might even go hardened now. "thumbsup"

so no more pullers for a while hu ?

I will have some more 7t's coming in within a few weeks.

Offroader- thats some spur stripping power ! :D

Can someone help me out with a reccomendation?

I have a new 2.2 AX-10 build. I wasn't sure what I had in store and a few weeks ago I ordered a Cobalt 10T just in case (glad I did...)

In any case, the more I've gone along with this build...the more I'm questioning whether using this with what I have in store makes sense.

AX-10 tranny (stock 14/87)
AX-10 Axles
Rooster Crawler Edition ESC
2 Cell Thunder Power 1320 Lipo (7.4v)

The battery will give up 17 amps constant and 27 amps burst.

I've got no experience with Cobalts. So I don't know what the current draw is.

So couple questions -

1.) Is this motor too much for this battery?

2.) Approx. runtime?

3.) Should I gear down?

4.) I honestly would prefer to have runtime and smooth throttle response more than anything else. I am not competing at any level, this is for fun right now.

Would I be better off with a 35T/45T traditional brushed motor for this application?

Thanks

mike, get a goat system, smooth and great run times, my colbolts are battery hungry but i love em

I am runnning a 5t And the 1500 elites don't cut it. Very short run times. I am running sub C's now. MAN what a difference in power!! I believe the cobalts can pull some serious amps. It ran very strong on the 1500 elites, but there is no comparason to the sub c batteries. A 5t on 6 sub c's is too much really. There is quite a difference between the 10 t and 5 t also. The 5t packs alot more power per volt. The 10t is smoother at a crawl. So we will be going to 8 cells with 9tooth pinions. that should do the trick. Way too much wheel speed anyways. With 6 sub C's over the axles, and 6 in tires 3/4 full of air softs, it still pulls the wheels off the ground by nailing it. Now thats something"thumbsup"

Does anyone happen to know if this will fit in a DMG DCV Pro with an AX10 tranny. This looks like a wicked awesome motor. I hear it is dead smooth too.

I REALLY NEED A COBALT PULLER MOTOR - DMIT!!!! i have a slow a@@ 55 tooth novak motor in my blackjack that is fully loded except the engine !!!! what am i suppose to do????? i do not want any other motor other then a cobalt !!!! will u please tell me when they are in stock i have a paypal witing for one , (or two ) if you have them
