Hey Guys,

With all the motors that have gone out, I just wanted to give some info about the numbers and settings.

On the header card you'll see a list of numbers:

21.8/.9r 12.50mm 1400/1408g

stator resistance, rotor diameter, rotor strength (N&S)

Numbers will vary from machine to machine.

Timing wise (starting points):

SC = 15*
Buggy = 25*
TC = 30*
1/12 = 20/25*


Rotors :

SC = 12.50mm 1550+
Buggy = 12.30 or 12.50mm 1350-1450g range
TC = 12.50mm 1400-1600g
1/12 = 12.30 or 12.50mm 1350-1450

These rotors and timing settings are baseline starting points.

I'm sure there are some instances where you may need a bit stronger rotor or a change in timing, but these setting should get you close

hm dont know another company that posts their motors numbers, rotor numbers, and starting points for their motors. Definitely the best customer service I've ever seen!!!! Also a fantastic product. Hauls my touring car around the track faster than the rest haha!

I'm trying to discharge my TeamScream AAA batteries using a Compettion Electronics Turbo35 charger and was wondering what the cut off voltage should be set to. I tried 3.6v (.90v per cell) but it's not working. What should I be setting the charger to?

The GFX will not go down low enough to discharge.

You need to be at a 3A discharge rate.

At 10A (min. GFX) I don't think you'll see anything, the discharge would be done so quickly.

Bummer, I was hoping to use the charger to discharge the batts but it looks like I'll have rig up something else.
Thanks for replying.

I have had this 17.5 motor for my RC10T4.2 for about a month and keep pushing it limits and finally have great results at our indoor clay track (ocrc). Final gearing is 78 spur/32 pinion, 30 timing. The timing evolved just as I read before, I had it at 42 and backed off to 30 and wow that was a bullseye. The truck performs better than most in the stock class and comes off the track at about 120 temp. I think there is still more room for a larger pinion. Great motor, form what I've seen here locally I have a winner except for my driving. Thanks Team Scream.

Glad you found a sweet spot you like!

Feedback we've received is even less timing.

Applying 8.4v input to that motor on the dyno with the rotor you are using and at 30* of endbell timing is over 2,000 more RPM then a D3.5 with 28* endbell timing with a stock 12.3 rotor.

Just for giggles try just a little less timing (4-6*) and leave the gearing. If it feels a bit slower on the top end drop the spur gear

How should I gear the 17.5 for TC compared to an Orca or D3.5?

With 30* endbell timing on a 90 x 40 track thats high bite and a few spots where you use push breaks we were at 48-96 with a 1.9 internal.

If you're on approx. that size but flowing, go 50-96.

How about on a 140x50 flowing asphalt layout?

Start with 50-96 @ 30*

You may end up a tooth or 2 lower at 35-38* timing.

More timing will generate alot more heat, but will pull hard down the longer straight and flowing infield.


Keep an eye on temps
