Default Mamba ESC Overheating

ok guys, I have just gotten back into the hobby and am running a B44 with the Mamba Max ESC, and a 6900 motor. I have the gearing set to 16/87 and the following settings on the ESC:

Timing - Low
Punch Control - 60%
Start Power - Low
Brakes - 75%
Brake Drag - 0%


My ESC seems to hit about 200 degrees after about 10 minutes of driving, it hasnt thermaled yet, but I have been watching the temps really close and pull it off the track to cool down. I have put a fan on it and it seems to keep it around 170 - 180 (Around the same temp as the motor). I have a few holes cut into my body mostly around the front air dams in the stock body. Does anyone have any suggestions on getting the ESC a bit cooler? I really would like to run without having to use a fan.

Thanks!!

The guys that run the B44 with the 6900 setup are running 14/87 and are right around 175 after a 6 minute race. The 4wd cars don't have much ventilation so all brands tend to run a little hotter. If the fan fits I would use it since runtime and power shouldn't be a problem for you.

The guys running LRP setups with the B44 at are track all use fans as do the Novak guys at are track just to help the ESC out some.

Thanks for the info! I ordered a 14 and 15 pinion gear the other day, so should be able to try it out this weekend. I may just leave the Fan on as you suggested.

I may also try to add some small vent holes right above the ESC on the body to try to let some of that hot air out.

Thanks!

Extra vent holes will never hurt thats for sure. While the Mamba Max is incredible resistant to thermaling it still could so a little extra precaution now will help to keep the esc and motor working well for alot longer time.

I think he said he is running a fan on the ESC.

Stand-by for RB FIVE to chime in & bash the Mambas

Yeah, I got a fan on the ESC. Just a heatsink on the motor.

My buddy got his ESC up to 280 without it thermaling...I even got a burn on my finger to prove it. Although his mamba came off the double sided tape and all the stickers are now coming off... It was

Very impressed with my Mamba so far.
