HH Cobalt Puller- Reborn page 35!

[BeeRC]

So, Raptor57, it sounds like you REALLY like your 5 turn Cobalt in your 12 pound super. When you say the 10 turn version would have been better in it, do you mean because it would run cooler, stronger, or....?? Was it actually faster on 8 cells than your 3025-8 on 10 cells?

How did you set up your rig for 120:1? (I assume its your Twin Force axled super with the TF tranny.) How else do the two motors stack up against each other? Would you say you actually prefer the Cobalt in your super?

Any idea how run times compare if using the same cells, or have you compared that?

I saw someone asked earlier but i didnt see an answer. How is amp draw / runtime on these? And the open end might be good for my scaler, dirt/mud/sand could flow in but also out easily. And what about replacement brushes?

[tsaun987]

Got it all mounted up in my ax-10. Fits in there like a glove!
Im using a mamba max w/ the cobalt puller, and it acts like a supercharged novak goat system.

I definitely need new gearing with this. Maybe an r2 would be good for it. With the stock ax-10 gearing, it has insane wheelspeed. Plenty of low end torque though

I'll post up some video of the mamba/cobalt tonight

Runtime depends on your trigger finger. I can get an hour in my 2.2 with a 2100 3 cell lipo. If I am heavy on the throttle I could whittle that down to 20 minutes I am sure.

As for replacement brushes, I am working on that. They are not available at this time.

What voltage are you using, and which turn?

Yes,I REALLY like the Cobalt motor. Because of the higher turns,just like any brushed motor,the 10 turn should have lower amp draw and higher torque rating. In turn,it should run cooler if the gearing and cell count is left alone. Yes,the 5 turn was a touch faster than my 3025-8.....even with twice the gear 120:1 on the Cobalt and 60:1 on my Hyperion and the Cobalt was still fasterEven with more cells on the Hyperion. Not much faster but it was faster.

Yes,it's in my super. I got 120:1 through a GD600. They are both a haws but the 3025-8 will overpower the Cobalt easily. The cobalt has the upperhand though with the smooth throttle response and higher wheel speed on lower cell count(less weight). Which do I prefer???????? Hard to say,they are both VERY good motors.

Can't run the 5 turn on 10 cells.......if you want it to last a while My outrunner will get longer run times. The efficiency of brushless motors will generally be allot better for run times anyway. Gearing,driving style and everything else plays a huge part in it.

10turn
9.6v (elite 1500's)
Stock ax-10 gearing (14t & 87t)
Maybe the wheelspeed is a little bit faster or just the same as the goat. It's kinda hard to tell but...
This thing is AWESOME JRH!!! The low speed control is amazing with the Cobalt Puller 10t!!!
Once again, excellent job man

Are these going to be a regular thing or a limited run?

[JohnRobHolmes]

THIS is a limited run. I am working on finding a factory to produce these for me on a long term basis, there are few brushed motor factories left in the world.

[BeeRC]

Raptor57, are you running a Mamba Maxx in your super with the cobalt motor?

By the way, has anyone heard any news on the to-be-upgraded version of the Mamba Maxx that has been referred to several times on here recently?

[chafee]

CAN YOU CUT THE coms? are they similar to lrp puller motors?

I haven't heard anything on the update yet.

You can cut the comm, but it is round from the factory. These motors are nowhere near the same as the LRP puller. My motors have more torque and rpm range, they have a totally different design.

Call Castle Creations they will tell you the basics of what you want to know. I havent gotten anything really technical out of them yet but they will give you the dummy version of what will be different.

I picked up a 7t from JRH for a rock racer project. I threw it in a bruiser hybred running tlt axles and a pede tranny. With 8 cells and a mamba maxx this motor is the bomb...

I will replace every motor in my scale/trail rigs with one of these!

It is exactly as JRH says, great low speed torque and tons of wheels speed...

Is that the turn you would recommend? I am running a hybrid with a stealth. been running a 35 turn in it but sometimes I wish it had a little more balls. Have you run it on 6 cells and if so how does it compare to a 35 turn?

I've only ran it on the 8 cell pack of 2/3 A's. I think JRH has been recommending the 10t for most crawler applications. I'm actually gonna use the 7t on a R2 2 speed tranny...

[Thorsteenster]

Save some for the rest of us BD!
I got a 10T for a 6th scale build I'll be starting soon hopefully.

[SpyderMonkee]

JRH, thanks for the Cobalt! Hooked up to a Max and r2, the low speed control was so much nicer than with the hyperion. Another one hit out of the park imo.

[Cloak]

After you told me about these at Nats, I figured I should keep an eye out. Haven't been online much with the house sale/purchase so I figure better late than never.

[SnailMail]

pardon my ignorance, bu i've seen tham somwhere else.... just can't rember where.....

one sec....

here
https://shop.graupner.de/webuerp/servlet/AI?ARTN=6340

groupner ultra motors, thet are DC'd though, so get em while you can (from JRH - about $200 cheaper )

there's more here, not just that one.....
https://shop.graupner.de/webuerp/servlet/AA

[JohnRobHolmes]

It is a similar motor, no doubt the graupner motors are a bit higher quality. Too bad they are discod. Brushed motors are falling by the wayside.
