And Astro wont make them for me, I literally threw money at Bob and he refused. He does know a thing or two about making motors.

Secret is out of the bag now, there are many astroflight motors that will work depending on the application. My super will wheel stand with pullmaster 1 motors and you can not stall it. Wheel speed is nits on 3 cell


Arg,, prices are going to go thru the roof now.

I have seen JRH motors in action and they are very simular and are a excellent motor also,maybe even better since the brush hoods are not external and those tend to getin the way of things.

John Robert ...are you having anyluck finding a supplier to continue reproducing these ?

I know who's making them:-P:-P

I just ran the 10 turn tonight. I like it ALLOT better than the 5 turn I ran in the Nationals. Mainly cause it's allot happier in my 12 pound super.

I was able to loose the gear reduction and gain a small amount of wheelspeed. The 5 turn worked great but got a little to warm pushing my pig around. The 10 turn pushed it around VERY easy and was running cooler than the 5 turn by a long shot. Sorry,no temp gun...but I can tell by the touch,the 10 turn is ALLOT happier. I ran it HARD for about 20 minutes and still had pleanty of power left. It started POURING the rain so I had to put it up. I played a few minutes on the firewood stack in the shop till I managed to bust the gears in my front diff. STEEL HELICAL GEARS....1:8 SCALE BUGGY STUFF.....SHREDDED:lol: It also twisted one of my 1:8 scale universal shafts nearly a 1/2 turn.:lol:

This babies got the mustard! Still doesn't have the GRUNT power of my 3025-8 but I tell ya,these things are AWESOME little motors. PLEANTY of power for crawling. As much as I tried.....I could NOT stall it out. It would pull itself out of the bind every time.

I was running on 9 cells and I'm happy with it. I'm a sucker for wheelspeed though. I'm gonna swap some diffs around from my other Twin Force axles laying around. I'll try to run a few different packs tommorrow to see what this motors like with 6,7,8......maybe even 10-12 cells:twisted:


I'm not saying the 5 turn is junk,it's a great little motor. For a heavier rig,the 10 turn is the better choice. The 5 turn would be a good choice for a 3-5 pound 2.2 rig. It'd probably have better run times and run cooler than it did in my pig of a super. Personally though,if I was gonna put a Colbalt puller in a 2.2,I'd run the 10 turn.

I'm gonna do some serious running with this motor over the next week or so just to see how it handles different things. As of right now,the results I see so far....this is my motor of choice. I REALLY like this thing.

These shots will explain what I am saying.
Clicky me

yeah, in my GC-1 i had to trim the plates some to get my r2d and a lathe motor to barely fit. too bad cause i would love to try one of these motors too. Even when i had an SW3, i couldnt get a pede or r2 to fit with a mag mayhem

JohnRobHolmes 11-30-2007 11:32 AM

I now have replacement brushes for these, and have a replacement armature source as well. For those of you who want one but can't fit it into your chassis, I have something on the way for you too. ;)

brushlessnut 11-30-2007 12:50 PM

:shock: how far out is shorter motor?"thumbsup"

JohnRobHolmes 11-30-2007 12:51 PM

2-3 months depending on how smooth the proto's go.

brushlessnut 11-30-2007 12:57 PM

sweet.the motors will not be losing much power if any getting shorter will they?

JohnRobHolmes 11-30-2007 01:03 PM

A touch, but it won't be much to shake a stick at. Smaller motors always have less power, but these will be a lot more power than a ceramic mag motor.

Cool! I can't fit the 2 1/2" one in my SW3, so I'll be looking for the smaller version.

Calderwood 12-06-2007 07:55 PM

John right now im running my light 2.2 tuber with with a mamba max, 6 cells nimh, an r2d with the 8 tooth, jordans, and wk axles, and a 27turn motor. i used to run a 55 turn but it was way to slow. The 27 turn is better but i still want more wheel speed. I know more voltage is in my future but am also thinking about one of these. Does a 5 turn on 8 2/3a cells make sense for me?

JohnRobHolmes 12-09-2007 10:36 AM

The 5 turn spins at around 2800 rpm/volt, so it will be faster than most 27t motors. On 8 cells it would really light up the tires and give you all kids of power and throttle control. It is my pick for 2.2 comp use right now.

JohnRobHolmes, how do you feel the 5t motor would do outside of a crawling application?

I am looking for a motor to replace the stock silver can motor in a Kyosho Blizzard. I'm hoping for more torque and speed, while still being able to run off a standard 6 cell pack and regular ESC.

Do you think the 5t Cobalt motor would succeed in this application?

Please let me know your thoughts.

JohnRobHolmes 01-10-2008 09:44 PM

I think the 5t would be pretty good on 6 cells, and the 7t as well with some forward timing.

LIKES2CRAWL 01-12-2008 06:21 PM

What's the word on these shorter motors?

Sounds good. Is the timing adjustable on the 5t as well (I'm assuming so)?

Nothing yet, still in the last parts of the design phase.

Yes it is.

bRIBEGuy 01-13-2008 09:54 AM

Excellent. Thanks for the quick replies.

Now I just need to convince myself that I can justify a $70 motor for a $180 Snowcat.............
