HH Cobalt Puller- Reborn page 35!

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.

yeah... it's too bad, but good in a way, technology progresses, and we are in a transition phase

and as for the graupner motors, they are awesome, but VERY expensive.
 
Did a little bit of testing with a 10 turn cobalt puller motor this weekend. Let me start by saying this motor could possibly kill the brushless revolution. "thumbsup"

I put it in Tyler's Bumblebee K5 since the extra length of this motor fits no problem in a Reign K2 chassis. Set up was TLT axles, Pede tranny, 14/87 grearing, 6 cell NiMh subC Venom pack. First I ran it with a Rooster Crawler. No problems at all so far. The bottom end punch is awesome and the throttle control is butter smooth.

Here's the big kicker, I threw in my old Super Rooster and guess what. The Cobalt Puller does come with it's own drag brake. :shock: Using an ESC with no drag brake I found that the motor's magnets were so powerful that they would provide drag brake. Now that's awesome. "thumbsup""thumbsup""thumbsup" Break out those old Super Roosters guys.

My only regret is that I can't get it to fit in my GC-1 chassis comp rig. :x I want so bad to run this thing in a comp rig. I'll try to get some video and more thoughts on this motor this week but after only a couple hours I can tell you I love this motor.

I have had to turn my drag brake down to use the motor on downhill sections :lol: Why wont the motor fit in a CG-1, does it hit the links?



John,
Please awnser my pm's i'm trying to contact you for over ea week now;-)


I will look through, I must have missed yours. Thank you for the heads up.

The tranny position puts the motor housing inline with the chassis sideplate and the cutout is not big enough. A lathe motor has maybe 1/4" clearance between the chassis and the endbell. Also there isn't enough chassis material there to remove and make room for the motor.
These shots will explain what I am saying.

May have missed it, but what trans are you running? I was wanting to run an R2D w/ one in Da Bull, but I doubt it will fit.

JRH- You got a PM from me too from sometime last month.:)
 
with thos cobalt motor you have to use sub-c's or lipos isn't it ?
or doesnt this motor have any influence on the discharge level?:?:

may i ask whay these motors are so expensive, ooh well comp drivers do what is takes to be the best on the rocks is it not!!;-)
 
Destroyer, could you send again, I cant find your PM. It has probably been deleted if it was indeed a month ago, old messages last about ten days in my inbox.

Crawl Rookie, the motors are expensive because of the construction. The magnets are powerful, the armature is harder to make. Unfortunatly once the current stock is gone the price will go up even further. These motors were made a few years back and to make them now will be more expensive, mostly because of the increasing cost of magnets and the fact that few factories make brushed motors anymore.
 
I've had mine for a couple of weeks and still LOVE it...

Just ordered another.

Thank you JRH for such great products and even better service...
 
Just re-sent."thumbsup"

Thanks Grizz. So you are looking at maybe 2.75" total trans/motor length (not including the input shaft sticking out the front)?

Not sure of that measurement. I measured from the front edge of the tranny to the end of the puller motor. I've got to remember the number now.

Edit: 1.5" as shown in the pic below.
