Looking for a motor that doesn't break the bank, but doesnt skimp on quality and smoothness either? I made the new Crawlmaster Sport motors just for you! Smooth starting 5 slot just like our other 3 models of Crawlmaster , but built into a sealed can! Combined with higher quality magnets than your typical sealed can, specific brush compound, and a ball bearing on the output, these motors deliver an incredible value, longevity, and driving feel for the price!



Find them at holmeshobbies.com, or at your favorite online retailer or local hobby shop. We dont require minimum orders for brick and mortar shops, so if your LHS doesnt carry our products it is easy to become a dealer and offer industry leading motors! I've been crawling for 17 years and put the experience into all 20+ types of crawling motor we make!

Is the 12t close to a 35t? Can't decide what to get for a stock TF2 with the 2-speed. Any suggestions?

It is noticeably smoother than his 35t sealed can 540, or the 21t and 27t 550 Trailmaster Sports I have in other cars, all running 3s from Hobbywing WP1080's. With no changes in ESC programming, it does seem less "punchy" which isn't bothersome, but the reduction in drag brake power was more significant than I anticipated. There was no discernible difference in speed from the 35t 3 slot 540 to the 12t 5 slot 550.



Overall I like it and feel like the low speed improvement was worth more than the $20 I paid for the motor. I am gonna have to figure out a way to get more drag brake though. I'm hoping there's still something to be gained in the ESC (he did say he'd been messing with the programmer) otherwise I guess even lower gearing/ underdriving the rear will be the next step.



How do you feel about running 4s on the 12t 550? I only ask because I was thinking if I can gear the car down 25% or more it should make the drag brake hold better (right?) and I could gain the lost top-end back by running 4s (obviously with a different ESC.)

Hi John, I want to order one of these soon for an SCX10-II raw builder’s kit.



I was looking at the chart on your site and see that the Crawlmaster Sport 540 16T is compatible with the stock gearing on the SCX10-II kit and RTR.



Would a 550 12T also work without changing the gearing? The KV is a bit higher, but not much. Thanks for your help.

It will be slightly fast, but the extra torque of the 550 should make it just fine IMO.

Yes, it will be perfectly fine.

What is the right 540 can to fit the capra? I have a Castle sidewinder 4 ESC but I don’t want to spend too much money on the motor since I read these new crawlmaater sport is more than enough.
I have a revolver and an yellow jacket which I use in my Toyzuki because of the fitting, and I really hate how they rumble at low speed. Any advice?

I'd think the 16t 540 Crawlmaster Sport would be a good fit. It's about a 1500kv equivalent.
If you need more speed than that, I'm sure the 13t is still a great choice.

I just got the 20t, maybe I can get a little more speed with a higher teeth pinion, what do you recommend?
