    You need to pay attention to motor temps. Very important! Invest in a cheap temp gun from lhs. I don't let my motors get over 160deg. You can use the touch method just be careful as these motors can burn if temps are high.

    If you can hold your finger on there for 10 sec, I am pretty sure its not getting over 140, even if you have superman fingers. You are probably safe, but pick up an ir temp device to be safe. It would suck to ruin a $100 dollars worth of equipment because you did not pick up a 15-20$ temp gauge.Harbor Freight also sells them pretty cheap.

    A 2 pole will run hotter,and has less torque than a 4 pole,you might want to watch you temp's close for a bit at 23-90.
    You should have a 20 or at least a 22 tooth pinion,in case you find heat trouble.
    The higher the kv rating,the warmer the motor might get,geared to high.
    On 2s the velineon has a top speed of around 35 mph with 23 90,the 4200 will run about the same speed at 20-90.
    I say 2s because you said track,any real track has a 2s limit.

    well its a track at my house and is a 2s limit with stock tires any motor and only gears that are from copany trucks came from big nice track with tight turns/ sweeping turns/straights right before turns so traction is all driver put 86s on with 23p seams good after whole battery could hold it forever

    I think with 3s on a track,the hole truck wont last long. I've said this many time's,I have 24 lipo's,one is 3s,and gets used once or twice a year. With out great throttle control 3s is just to much for a slash,and more so on a track.The gearing is fine at 20/90,(4.5),but there is a reason most all sc tracks have a 2s limit.
    With that gearing on 3s the slash is capable of 45 mph,but it's been my experience that a two pole motor on a track with 3s wont last long.

    the venom 4200 motor is only rated to 2s.

    If you're using a VXL-3s ESC, you should be fine, according to traxxas, there is no motor limit. Unless it a 4 pole motor, then it wont work with that ESC at all.

    You're gonna really enjoy the SCT 3800 combo - tough as nails. i run mine on 2s - prime time!!!

    Hope you have the mmp esc,the sct castle wont take 3s well either,I run three castle systems.
    And am quite aware of their limits.
