how many turns is too low for a scaler/crawler.......reason im asking is I was running a 27t ....seemed to do ok....ran a 55t this weekend and it was really slow.....I needed more oomf to get through mud....lol....still have 27t motor avail but in my pile I have brushed 15t/19t/12t....... would a 19t motor be too fast?.......all input is welcome

i run a 27t in my wratih and its about the perfect mix for me. plenty of speed and still crawls. i think a lot of guys run 35t in scalers that are set up for crawling more.

thats what im seeing too im gonna try this 19t motor i have to see what the other end of the coin will drive like...55t was too slow for trailing...would be good for crawling though...if it too fast then ill stick with 27t..thanks for the input dude

I think you will find that the 19t will be too fast and heat up quickly, 27-35Tmotor works well in a scaler. Anything over 35t is too slow in a scaler for me.

thats what im expecting lol.....i just wanted too see how fast.....the motor i have is a reedy challenger 19t...they came in 27t as well and i can still get brushes for it...i just want a rebuildable one all i have thats rebuildable is 55t and 19t...maybe i can find a 27t armature for it........if you know of one lemme know

Consider those reedy motors are fixed timing at 24 degrees more than likely....Good speed but hardly the low speed control you can be getting from it and still have some decent speed.

If you can find a cheaply priced mod motor with adjustable timing just use the 27T armature from the reedy motor inside the mod can and set timing to zero or -6 advanced for longer brush life.

This is what ive been doing for motors recently.

Im using a Trinity 27T armature inside a trinity mod can...Works great..plenty of speed on a 2s and geared right has acceptable low speed control for crawling...Im using a 16T pinion with mine and the stock 87T spur gear (rtr scx10)

Or probably a less expensive alternative is a Holmes Hobbies 27T torque master sport...Buy the motor once and you can buy whatever armature you want for 20 bucks and make it any turn you want.

Motor on the right is a fixed timing 24 degree motor...Motor on left a mod motor....easy way to build a sweet motor.

Like most said a 27T or a 35t are most popular...I would say though most will choose to run a 3s battery with a 35T to gain back speed lost over a 27T...just have to be careful you don't start breaking everything in the drivetrain without some upgrades.

I agree with what others are saying here. I run a 27t stock axial motor in my trail rig. not sure how old it is but it just keeps going. And they are cheap to replace if need be.

The wise old owl said; one, two, three, crunch!!! Just kidding, couldn't resist the old tootsie roll pop commercial. I think around 35 to 27 is ideal. 19 would work, but you would lose a lot of torque. Like everything it is balancing the trade offs.
