    Angry Slash 4x4 with 1/10 mamba max pro sct 2400kv motor.

    It over heats with the new system in it. Doesnít actually shut off, not sure if it even has a thermal shut down mode. Anyways geared 17/54 with 2.2 trenchers it would get really hot on 3s. Then geared 13/54 on 2.8 trenchers it stil would get really hot. What am I doing wrong. Has tekno cvds if that matters and all bearings on the truck seems fine.

    welcome to the site. you aren't doing anything wrong, that system is minimally adequate for running 3s in a heavy truck

    I know you say that but I have had different experiences. It runs great for me even on 4s. To the OP I'm not sure where you found a Mamba Max Pro. They are few and far between. I do prefer the Mamba X esc. It is way more efficient, waterproof and can be programmed in almost limitless ways.

    Welcome to the forum and the addiction! You are among a group of people who share the love of the Traxxas Slash 4x4! If you have any questions please feel free to ask. Remember we are here to help!

    The Mamba Max Pro does have a thermal shutdown. If it gets too hot it will Cease to operate until it comes down to an acceptable temperature. What exactly is getting hot?

    Yes itís the mamba max pro sct version with a 2400kv motor. Both are 1/10 scale. Esc seems warm but motor seems to be hot, really hot, on gearing and such that I stated above.

    The truck is too heavy for the motor?

    No. The higher the kv the more torque it can make. That is why larger vehicles, like the X-Maxx, came with a 1600kv (initially) and now a 1200kv motor.

    Hot motor + cool esc = Undergeared
    Cold motor + hot ESC = Overgeared
    Hot motor + hot esc = Way overgeared
    Warm everything = Just right

    I just noticed you have it geared 13/54! I would never gear it under 18/54. That is the O.G. El Sob special motor system. I know for a fact that it will work well with the truck unless it was hurt from being geared wrong and overheated too many times. That is all I have run for several trouble free years.

    I first had it geared 17/54 and it got hot, I didn’t know it would get hot by being under geared, so I assumed I hadn’t it over geared and went down in teeth count when I got bigger tires. I have a 21 or 23t pinion at home. I’ll have to try that next and see.

    Welcome to the Traxxas forums!

    You should pick up an IR temp gun to know actual temps, not subjective temps.

    They can be found for a very reasonable price at many places.

    Here's one for $20 at Harbor Freight:

    I have had that same motor system in a truck since 2012! It still runs beautifully! After all of these years I have no complaints

    i suggest gearing it down to 13/54 on the 2.2 trenchers and then running it on 3s and checking the temps to see if they are any better. Also invest in a heat sink for the motor if you don't already have one. An aluminum motor mount will also pull away a ton of heat from the motor, and can help dissipate heat.

    This is best advice so far.

    The problem here is the word "hot". Until we can see some real temp numbers this doesn't make alot of sense yet.

    I have a buddy who feels his finger is about to burn off touching 120 degrees.

    As I said before, 18/54 should be a good start. If you don't have a way to measure the motor temperature it's almost impossible to guess how hot it is. If you overheated it too many times, you will ruin the motor and its performance.
