CrawlMaster 540 11T vs 13T

[MAGNUMB]

looking for suggestions on if I should go with a CrawlMaster Pro 11T or 13T on my 2-Speed TF2 that weighs in close to 9lbs with 2S. This will mostly be a trail rig with some rock crawling. I hear the 16T is a bit too slow and 1st gear is hardly used.

How many motors do you want to replace?

I only ask, cause I've been where you're at.. lol..

I tried a handful of different motors. Best option I found, was a 16t Crawlmaster pro..
Problem was.. Great crawling in 1st gear, Great wheel speed in 2nd gear..
Which means.. horrible speed in 1st and zero crawling in second..
This isn't just limited to brushed.. I swapped in a brushless HH puller pro and it felt Exactly the same, as the 16t Crawlmaster pro..

I think the problem is in the tranny gearing, not the motor.
I swapped motors, changed pinions (up and down).. I could get One gear, to work well, all around, but not both gears to work well enough..

That's a bit of a lie.. 4s makes a Huge difference! Lol..

I would consider bumping up to, atleast 3s.. IMO..
The 16t Crawlmaster pro was most likely, good for most ppl out there..

I ended up with a single speed tranny and a 3500kv puller pro, mixing between 3s and 4s..
I just swapped in a HH 2700kv Stubby and plan to run 4s, this year..

I like being able to control my speed with the throttle, not the motor controlling my speed..
And things tend to get a little silly, when I grab a handful! Lol..

Thanks for your response.
I ended up ordering a 13T Team Brood Specter a couple days ago....I wanted a 14T, but they don't offer that in 5 slot armature. I think I'm going to get the new waterproof HobbyWing ESC and run 3S as my AE-2 won't handle that many cells. I'm might end up using this rig for more trail bashing and faster hill climbing and then might build anther TF2 for just crawling.

[winnerone23]

Do you have a CC BEC?
I'm pretty sure the AE-2 will handle 3s, perfectly fine, if you're running a bec.
It's the internal bec, that can't handle it..

Hopefully someone else will jump in and confirm this.

[MAGNUMB]

I do have an external BEC....didn't know it could handle it. Thanks.... Although I do like the drag brake options on the new hobbywing unit and it's only $41. Might just grab that and sell my AE-2 for a few bucks.

[winnerone23]

Good deal

[JatoTheRipper]

I'm anxious to hear how you like that motor. Please update us.

You'll love the HobbyWing WP 1080. You won't need a BEC with it.

[MAGNUMB]

Will do. It's going to be awhile before I get it ready to go. I'm completely tearing it down and setting it up with links and lowering it about 1/2". I excited to try it out should be a smooth setup.

Sorry to bring this back from the dead. I just picked up a Tf2 with 2 speed transmission and plan to use a Crawlmaster 16T and Hobbywing 1080 esc.
From what I gather I will be ok to use this motor with 3s?

[Natedog]

Yes, that motor and esc are both fine on 3S, but ime the lower turn 5 slot armature motors require much more maintenance and need to be rebuilt every month or two. 550 21T motor on 3s is excellent and lasts a long time.

Just looking for more info on "lower turn 5 slots needing more maintenance and rebuilt every month or 2"..

I don't really consider a 16t Crawlmaster, a lower turn.. which turn motor did you have?

I ran the 16t Crawlmaster pro on 4s, for well over a year, in my Scx.. beat the P out of it!
A quick clean, with electronic motor cleaner, and sold it. Brushes and comm were both still good. He ran it for 2 years, before switching to brushless. (I don't know how much rebuilding he did, so I can't speak for him.)

I've been running HH 11t 500 pullers for a few years, in my pro truck. Which got many more hours put on them, then 95% of ppl run the scale truck. Like 3 hours a day, minimum..
I'm willing to bet the still have Nevada dust in them, from World's 2015.. lol..

Yes, it's a 4lb truck but 21 hours of run time a week..
I feel the Crawlmaster and Puller motors, take less maintaining..

Then again, all my scale trucks run HH brushless setup's, now. Lol..


Just looking for your experiences.
Thanks
Troy

13T and 16T, YMMV, I can't speak for the 500 Puller. I know the 5 slot has two more slots and wound differently, but I haven't seen the value in that. I'd rather run a slightly larger, more torque oriented 550 motor for less money that doesn't need to work as hard to do the same work.

Troy, single speed trans still?

The value in a 5 slot, isn't always seen. It definitely depends on what you use it for and how you use it.
Personally, if it isn't a 5 slot, I don't own it, unless it's brushless.

The low end, smooth start, and speed, is why.. 3 slot can't do what a 5 slot can do.

Draw back.. you don't get the exact torque or drag brake, from a 5 slot..
A trade off, I can handle!

Hellz Yeah!!!
I still have the 2 speed, but I don't ever see going back!
With the right motor, the single speed covers all the bases.
Maybe if I was making a low rider/drift truck.. lol..

What do you mean by this? Which means.. horrible speed in 1st and zero crawling in second..

It was slow in 1st an no torque in 2nd.

For example. If I didn't have enough speed to bump up a rock, I had to bump up it in 2nd. But 2nd didn't have enough torque to crawl up the rock, once I got bumped onto it.

It crawled Amazing in 1st and was like a prerunner in 2nd..
Mid range Sucked!

Now. This is just my opinion.. You may love it, just the way it is!
My idea of scaling, means being able to throw 10' roosters! Lol..

Never seen or felt any value over a good 550 21T, but to each their own. I can also buy 4 Traxxas 550 motors for the price of one CrawlMaster Pro 540.
Yes to at least 3S for all crawlers lol.

2-speed is still fun, love throwing bigger rooster tails and pulling wheelies!
