i tried running my mamba max with LRP 1 star BL motor. My car went reverse and after 1-2 second it went forward. Reminded me of flintstone car.
With the 5700 mamba motor, i could not feel any difference if compared to the sensored brushless cause I also own LRP Sphere comp and Novak GTB.

Thanks anyway, Drew.

Dont get me wrong, the mamba max runs flawlessly with its own motor. I could not feel significance difference with the Novak's or LRP's in term of smoothness.
I have 3 GTBs and 2 Spheres. Almost a dozen motors from both makes. All of them dont really fulfill my need because they require gearing in the range of 8-10.5 for TCs.
Since I am running 1/10 pan cars, it's impossible for me to gear that much because the biggest spur is around 92-95 and the smallest pinion is around 12. I have a big headache if my foam tires are still new. The damn things keep on thermal or wearing out my spurs.
As I switched to Mamba, I can now gear with 90/16 and still have plenty of punch. I can now program my brake and throttle curve to suit my liking. I can even run 11.1 volt lipo if I want to. Higher voltage means less current draw which translates to higher efficiency and run time.
Mamba max is just awesome.

No i know, i have borrowed a mamba and ran it for a meeting in my touring car but i prefered the way the GMs and Novaks ran, when i ran the 4.5 with the GM in my pan I didn't have any problems with gearing or over heating. After a 5 min run the motor and speedy were less than 50 degrees C. I did gear higher than what i do for my touring car as you have less friction in a pan. I ran around 6.2 or 6.3 (90/15) and the car ran perfectly.
Thanks, Drew.

You can send in your motor and exchange/replace it if you want to run sensored.

the thermal shutdown is there for a reason. I was told to keep the motor temperature below 75 degree C in order to prolong its life. I also noticed that the novak esc would shutdown the moment the motor registers 75 degree c. My novak motor lasts almost forever if i keep it below 75 degree c.
LRP and perhaps GM or orion can withstand up to 90 c without any problem and that's why the esc engineers dont bother putting any motor thermal protection. Whether that this will effect the life of the motor, I am not so sure but so far none of the X11 motor has gone bad in malaysia, even if the track temperature reaches 54 c quite frequently.
