just woundering if the 13 turn motors came in. can these motors run 3s all day?
thanks, Erik

Hey John,
I have a lcc running a novak ballistic crawler 18.5. At slow speeds it is very jerky(mainly on down hills). Im also using a mmp for my esc and I got the throttle curve set so that i can crawl really slow. Then the curve ramps up at the end for good wheel speed towards the end of the throttle. I really want the smoothness of a brushed motor again. I ran a traxxas 21T for awhile with no problems but it was to big and heavy. Im really diggin these motors and I would love to get one for my lcc to get that buttery smoothness of a brushed motor again. What wind and timing setup would you recommend for slow speed crawling and the ability to jump some gaps.
Thanks, DS

john, i was wondering if i could pay now. and you ship when there ready. "thumbsup"
A 28t would be my suggestion for 6s use. You could probably get away with the 20t, but it would be a shorter lived motor.
see above!
Yes they can! I had great luck on 4s even. Nice and cool for the most part, and waaaay more wheelspeed and torque than I needed. It was like having a nice and easy motor on the low end, but with a huge punch on the top end.
On the LCC I would say the 16t is your best bet with stock gears. Maybe even 13t depending on your pinion size. If you like the speed of a 21t motor, we could even wind you something custom and faster.
You can pick it up as a custom tonight, or wait till tomorrow when we get inventory refreshed on the site. We got armatures back today and just need to count and ship out all previous backorders before putting new inventory up.
Thanks for the interest fellas! I can guarantee they will be the best 540 you have used "thumbsup"

John, I've just tested the CrawlMaster 16t with my Mtroniks Viper Eco20 ESC and a 2s 2200 Lipo. The test was done with the motor loose, disconnected from anything, just to check its smoothness. I don't know if it was something about the ESC, but the motor was not turning very smooth. It presented an intermittent movement at any constant speed (most noticeable at very low speeds). Anyway, since I'm new to RC cars (all my RC experience comes from gas model airplanes), I don't know if this is the normal behavior of a (disconnected) brushed motor or if I need to change my ESC. Any help is very welcome... thanks

Most likely gonna be an issue with that particular ESC! Brushed crawler motors need ESCs with the proper software/firmware for crawling. Castle, Tekin and the HH BX esc all have firmware for crawling. EX: When the FXR first come out it had issues like you describe. After some studying on their(Tekin) part and a firmware download later it was solved. Also a no load motor/esc run is not really a good test. Installed in a rig is really the only good way to get that "feel"."thumbsup"
Indeed. Test it out in a vehicle and see how it is. It may be the ESC causing the jerkyness too.

Guys, thanks for the valuable information. I'll make a test with a hi-lift 3 speed tranny and will let you know if the "jerkyness" ceases under some load.
John, you said that CrawlMaster motors seem to suffer less wear. Sorry for the "immature" question, but which parts tend to deteriorate under normal use (besides the brushes, of course)? Do they need replacement or regular maintenance?
Thanks again...

Brushes & comms are the only real wear items.
Bearings/bushings wear as well but fairly slowly (provided they are kept clean & lubed). Don't cram the pinion/spur mesh, keep the gears clean to reduce armature side loads for longer bearing/bushing life.

still havent recieved my motor. do you have a tracking number?

anything?

outstanding! That is all i can come up with.
I just installed and wired up a 16t crawlmaster in my boys rig.
It runs a Tekin FXR, castle BEC, and 1300mah 3 cell lipo and a 12t pinion. Ax10 based rig with UGC F4.
It runs so smooth and slooow at the bottom and then hauls ass when you want it to. Its great, nice work.
I also have a rig with a 35t torque master pro hand wound that I like, I was looking for a motor a little bit faster and the 16t crawl master fit that perfectly, if a 90t spur would fit in his rig I would put that in also but it wont fit not a problem though.

So since you named this motor after me and i was here first do i get a free one :roll:
If you haven't gotten it yet, what is the order number? Can't find your user name in my database.
Thanks for the feedback! Glad you like it.

I have ran a few packs through the Crawlmaster 16 Turns on my 2.2 Berg comp truck. Advanced timing at 6 degrees.
Rockshow SS Berg Chassis, Clover Design axle tubes, 300 axles, 12T pinions, lightened running gear, RAS Custom's brass knuckle weights, TP 850mah 45c 11.1v packs, two mamba micro pro's (213% drag brake), CrawlerInnovation Khaos-Rover tires, SLW's, about 5.5lbs RTR.
1. The start up and low speed crawling is like no other motor I have used. It is super smooth and consistent on startup and at very slow crawling. Torque to get out of holes and binds is excellent too. I tested with Crawler Innovation's Khaos-Rover pin tires and they work best at super slow speeds. You would not believe the super slow front digs I can now do with the Crawlmaster's. The K-R's pair well with this motor setup. I have no other comparision on the low end creep ability of these motors other than it's jaw dropping.
2. The low end to mid range power is really consistent. No dips in power. I get consistent wheel speed. Slow, medium or fast.
3. The top end of these motors is just as jaw dropping as the low end. I can blip the throttle and jump the truck 3 feet if needed. It's truly amazing. I can only image if you ran 4S on them!
4. Drag brake is a touch weaker than the TorqueMasters I was running but is not a big issue. They are two different types of motors.
5. These motors sound like competition rock crawler motors!
