Mann0mann- that battery isn't quite enough. For the 10t I would say you need at least a 1600 15C pack.

TK- I can't tell you if it will fit. How much room is around a normal 540 motor in the rig?

Contracted- I have 7t Pullers available for presale on the site again.

Cobalt Puller 7t--limited stock
 

http://holmeshobbies.com/skin1/images/Guido.jpg

I have a new batch of 7t Cobalt Pullers, 4 in stock and 40 going to the machinist on monday.

These can be shoehorned into an sw3 with an r2 tranny, but they are longer motors than a standard 540. The torque is much higher than any other brushed motor that works in a crawler. More wheelspeed, more torque, more power in general. With a 7 slot armature you also get much better slow speed control as compared to normal brushed motors. I run these in every one of my rigs now, with exception to a few scale rigs and my really fast bashers. Yes, they are in fact powerful enough to make me leave outrunner motors for a while. My avatar is the armature.

Get your foot in the door while you can, these motors get snatched up quick

Good God, that is sick, great vid!

...

Not that I need one but I had to get one :-P

Done"thumbsup"

Do you have something comparable to this but brushless?

Not really. The pullers have torque, speed, and low speed driveability. The closest brushless would be a novak goat system but they don't have the drag or torque. A fast outrunner would have the torque but not the low speed resolution.

got one too for my prerunner/crawler

Are you serious, these have more torque than my goat systems, if so:shock::)"thumbsup"

Yes, the stator is much larger than the magnet on the Goat. It is also longer, and has more commutation cycles per revolution. All adds up to more torque.

Would a 7T with 21T/87T still have enough torque for crawling?

Just picked up 2, thanks JRH"thumbsup"

Yep. You could gear it to the moon and have enough torque if your batteries would deliver the amps.

Sorry to get off topic, but what are the rpm per volt for the 10t and max volts?

I measured the 10t at 1800, max voltage 4s lipo.

The 7t is listed at 1800 by the manufacturer, but I think that is loaded. It actually spins closer to 2300 by my last measurements.

So what kind of battery do you recommend? 20C 11.1v LiPO?

A 15C 2100 seems to do the trick on the 7t. You could use a smaller battery with 20C discharge.

paypal sent.

thanks JRH!

anychance I will get one of those bad a$$ HH stickers with it?

I need to get more stickers made. Already given out about 1000 of em, and I have run out.
