Default Can a Mamba Max ESC work with a Novak 13.5 Brushless Motor?

I didn't see a formal thread on this topic so I figured I'd start one.

I finally broke down and bought a SS13.5 to use with my Mamba Max. I waited for a guy at the club to try it first because I didn't want to be the guinea pig...and it worked.

Does anyone have any suggestions on setup? I've been told that you need to gear these taller than you would a brushed motor. Mine worked well but it didn't seem as punchy as my Co27. After a 7min main, my motor temp was only about 96'F.

Here's my setup:
Truck: XXXT MF2
Gearing: 19/86
Batteries: Matched IB4200

Brake Amount: 50%
Drag Brake: 35%
Start Power: High

Sub Trim: 29-Forward (3PKs with Spektrum)

Usually with the brushless you should go to a smaller pinion than brushed. And I have done so with my 5.5 and 7.5. With my 10.5 I actually went up, one tooth higher than brushed and my temps are in the 115 range.

Though I didnt think it made sence, I called Novak to ask about the temps and was told in the 150 range is where you will get the best performance for both the ESC and Motor. Thermal is 170 to 180.

I dont think this answered your question because of your mamba, but it is probally a good start.

Call Mamba and see what there recomendation for ESC temps are, and then you can figure out a nice average temp that is safe for both your motor and esc.

That is where you should be geared.

Try advancing the timing on the ESC. That should help.

I've been tossing around the idea of using a Novak motor with my Mamba...did you just zip tie the sensor wire out of the way? Any cogging or weirdness at all?

I didn't use zip ties because I didn't want to have to cut them every time I switched to and from mod and stock truck. I used a wire wrap that looks a corkscrew and bundled the 3 motor wires with the sensor wires.

I got a very small amount of cogging/stuttering but it wasn't bad - more of a nuisance. I think it only happened 3 times in a 5 min qualifier but it only happened from a dead stop. I think the more forward trim you give the throttle, the less this will happen.

I gear my 13.5 at 21/86 in my XXXT MF2.

I also have a 13.5ss with my Mamba Max. Very light cogging at the initial start but when rolling there is none. I can live with that, plus having reverse during practice is a big plus.

Have you tried reducing the start power to eliminate the cogging?

that may be an option. I actually found at least on my first mamba max (the current unit didn't cogg at all) that I needed to increase the power setting (not punch control) and it cleared up the cogging.

Is the mamba max as smooth as the Novak GTB or the LRP speedos?

I heard that Castle Creations are now working on software for the ESC that will make work with the sensored motors with no problems at all.
Is this true?

I've never owned a GTB but if it's anthing like the GTX (which I've owned) the GTB would be smoother. The cool thing about the Mamba Max is that you can update the firmware when newer versions are released. Those updates could address smoothness or resolution of the ESC.

I've heard that too but not from anyone from Castle. :-( That would be huge!
