    What kV motor do you run?

    Looks Iíve fried the ESC in my truck. Looking at replacements and am curious about which kV motors people are running. From my understanding lower kV is basically more torque and less top speed and the opposite goes for higher kV. I think for me a slightly lower than stock kV motor would be beneficial since top speed isnít really what Iím after. That usually results in mass destruction if you get a little carried away. I think with different gears and more battery the same top speed could still be achieved pretty easily. Anyone have any extra info on motors and their capabilities before I pull the trigger on my theory? Any info is good info, Iíd like to hear it all. Thanks!
    If it's not broke, don't fix it! Just upgrade it..

    I'm running a 3665 3100kv in mine currently on 3S with a max10 sct esc. Had some issues the last time out and I'm not sure if it was my older packs dipping and tripping LVC or not. I need to get more wheel time on it to see how it does.

    I know with the max10 sct/3660 3200kv combo, I was overheating the motor (has a sensor wire) even with a fan on the motor just running at the skate park on 3S. Which is why I tried a longer motor with a bit less kv.

    If I end up having heat issues this spring with the esc, I'll replace it with a spare blx185 I have on hand.

    I use a Hobbywing SC Max 10 Ezrun combo with the 3660 3200kv motor (5mm shaft).
    I drive it on 2S, with a 15t pinion 54t spur, ProLine Badlands MX28 tires.

    No issues with overheating, unlike olds97_lss, but he drives on 3S (don(t know what gearing he has).

    I like this combo (have the same in my Slash 4x4).

    I was running 3S, 13/54 with trencher 2.8's, MIP X-Duty axles.

    Video from then:

    This was later with the hobbystar 3665 3100kv and 14/54 gearing:

    Did you have any issues fitting that 3665 in a stock chassis?

    3660(550 size can) is the biggest drop in motor.

    I had to cut a bit of the esc mount off and I ground out a bit of the chassis under the motor.

    I put a castle 2650kv in and had to grind out a bit as well.

    What motor is that specifically? Got a link? What size pinion do you run? 3S or 4S? Sorry, just wondering for future reference.

    I got it back before they made all their motors sensored, but I think this would be about the same.

    I'm running an 18 t pinion on 3 and 4s. 4s is a bit on the crazy side honestly, but fun sometimes if I feel like fixing something.

    I run a ET3S and 5000kv motor and it’s too fast on 3S and never overheats.
