    Hey guys and gals, I need some help making a decision for my 2wd slash. I'm looking for a good sensored brushless motor to run with my castle creations mamba max pro esc.
    Now keep in mind my truck is far from stock! It has aluminum all over it and I just installed the STRC lcg chassis conversion kit so it's race ready and worthy, but I'm running a castle creations sydewinder 6900kv system right now, which is way to much speed for short course track racing and it's not very smooth on take off and exiting corners. I'm looking for a good motor to run with my mamba prob esc and want a sensored one for smoother takes offs ad cornering. Also it has to be at least 4000kv for 2 reasons!! 1st is because of the weight of the truck!! It weighs about as much as a stock 4x4 slash does so I need enough torque and kv's to keep up with the lighter trucks on the course. 2nd reason is because I want it to be faster then your typical TRAXXAS velineon system because if I use that system then it's just another slash 2wd with a velineon system hahahaha. I have absolutely nothing against the TRAXXAS velineon system I think there awesome and reliable, I'm just going for a one of a kind 2wd slash.
    Just to give yas an idea of how much extra weight is on my truck here is a list of the changes and upgrades I have done up to this point:
    1: STRC- aluminum front and rear a-arms
    2: STRC- aluminum front and rear shock towers
    3: STRC- aluminum front bulkhead
    4: STRC- aluminum motor guard
    5: Golden Horizons- aluminum transmission housing
    6: Traxxas- aluminum toe links and steering links
    7: Traxxas- aluminum castor blocks
    8: Traxxas- aluminum front steering knuckles
    9: Traxxas- aluminum rear hub carriers
    10: Proline- steering linkage
    11: RPM- front and rear bumpers
    12: Spectrum DX2S
    13: Castle Creations SV3 6900kv brushless system
    14: STRC LCG chassis conversion kit
    15: Proline Trenchers on the rear and Bow-Ties on front
    16: Traxxas- aluminum front and rear shocks

    Pretty sure that's all haha thanks for looking and any info and/or advise is much appreciated. Oh and I'm looking to spend around 100$ on a motor, can't go much higher then that. Thanks again!

    Well I tried the thunder power 10.5t brushless motor and it just isn't quite enough, so I'm wondering I maby I shouldn't go with a 6.5 or 7.5 turn?!?! Stumped at the moment lol

    If your trying to go faster you will need a higher kv motor than you already have. If you can in done the same kv but sensor end you would be set. In all honesty I'm surprised you manage to run that high of a kv motor without major cogging issues. But the high kv is the reason it's not so smooth. The speed of the motor with only 1v difference is huge.

    Well with the 6900kv system I'm running 3s lipo so it has lots of juice but when I go racing your only allowed to use 2s, which isn't enough for that motor. Plus 50+ mph is a little much for an offroad dirt track lol I'm thinking about going with the track star 2 pole sct brushless motor! Have you ever used one or know anyone that has?!

    Even if it is too over powered if you have a castle program card you can tune to your liking
