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.

Just placed my order...

Thanks JRH

I am trying to get shipping costs to Canada.
I sent an email but haven't heard back yet.
When I tried to order from your site it said to email you? Did you get my emails?

What if we're still using 7.2v NiMH packs? Will they supply enough power to run one of these motors, or do we need to make the jump to LiPos first?

Thanks,

Hi JRH, on this note i have a sidewinder i am going to use with this motor, what battery that you have in stock would you recomend? also a balancer for my hyperion chargers? lmk so you can ship all at once.

How do the Cobalts play with The Sidewinder?
I'm thinking I might try something else in a comp rig I'm building rather than the Goat system I was going to use.
Have any kind of combo price?

So whats gonna be the specs difference between the Cobalt Puller 7T and your TorqueMaster M10? And when will we be expecting the TorqueMaster available for sale?

The m10 is still in proto phase, I have a few designs that are kicking around. It would be less power than the Cobalt Puller.

Cobalt and sidewinder are just fine together. No combos right now.

I have a shipment coming in of lipo, I will need to get some 7t testing. I don't remember if I had 1800's or 1650's sent in, and I haven't been able to test 3 cell 1650 15C packs with it yet. On a 2 cell a 1650 15C pack will cut it if the gearing is low (13/87 on an axial tranny).

What pack? What cells?

I have probably received it, but not replied yet. I will be able to respond to emails tomorrow after class, and before I ship.

Hi John.

I also just emailed you to get a price for postage to Australia , am ready to order asap.

Tim

How do you think the C7T w/ Sidewinder would be on a 2s A123 pack?

Could you also find out what pinion Badger was running in the vid with the R2 tranny and 3S lipo.
I'll be using this in a rock racer as well and his wheel speed looked spot on .

Shipping is $15 for non insured, and $25 for insured. If I haven't responded yet, don't worry as I have taken some motors out of inventory for international orders.

It would work pretty dang well IMO.



He probably uses a 13t, but that is a question for him. You could try asking him.

Thanks John , payment sent from your OZ customer.

Just was on our OZ crawling forum and saw that you post there as well , great stuff.

Can't seem to send payment through your site says to do it by email could you send me an invoice for a 7T puller.

I have sent you email before.

got a 10t in my comp rig and TWO more 7t's on order :twisted:

Alrighty, I'm in. I 'm gonna move my 5T to my Rockracer and use the 7T in the slingshot...

Cheers,

Rob

Holmes: Need s/h fees to Canada. Please reply ASAP. Thanks.

This come in yet? if so send me the invoice for the other stuff i asked please.
Thanks

did the machinist get the job done?

Nothing today. Last Friday they said it would be Wednesday at the latest- hopefully they are right.

What does one have to do to get a shipping estimate over here??? Sheshhhh
