    Question?

    I think I just toasted the motor in my slash 4x4. No power when it's on the ground but wheels will turn if I jold it up in the air. I already have my sons motor and esc at traxxas right now for the second time and was wondering of I should switch to something else like the castle or just stay with the traxxas motor we are both running 2 s lipo with stampede tires. Any suggestions ?? Thx

    I had the same problem. Magnet separated from rotor. Traxxas replaced it. I sold it and bought the 2400 system.

    3800 has a smaller can size. Will have less torque, and will run hotter. 3800 also runs max 3s lipo, the 2400 can run 3s-4s and still run cool.

    Also, if you're buying the motor/esc combo, the 3800 comes with the sidewinder which is definitely not as good as the mamba max pro that the 2400 comes with.

    The 3800 is more for track applications where 2s is used. If you dont run at the track, but just bash and play with the truck, the 2400 is what you want.

    We just bash out in the desert we live in az. So the 2400 will have a lot more power than the traxxas motor?

    Get the 2200. It runs cool no matter how hard you run it. Especially in the desert. I had the 2400. It was great no doubt. I switched to the 2200. It is a beast!! 3s super fast. 4s insane!!

    Yes same motor.
    Im seeing lots of mention of the 2400 and the 2200.
    What I dont see is the 2650.

    The 2400 is the same can diameter as the 3800 but longer, Both 1400 series
    The 2200 and 2650 are both 1500 series with the 2200 being longer.

    The 2650 is made to run 2s-4s with the gearing chart showing 16-24/54
    The 2400 is 3s or 4s with gearing chart showing 10-14/54

    Castles gearing chart is conservative but the specs they release shows the 2650 to be a much more robust motor and if you are looking at them side by side its rather obvious.

    I ran both and found the 2650 to be easily adaptable to run the track or bashing by simply changing batteries.
    The 2400 doesnt like 2s and will heat up.

    IMO the 2650 is the way to go for castle products in this comparison. No matter how I ran it the temps stayed down.

    The 2200 is just too tough to tame. I tried one of those too and found I couldnt get a balance between speed and torque. These are all like dropping a big block engine in a VW bug but the 2200 is like the big block then adding NOX.

    Motor can comparison left to right. 1515/2200, 1512/2650, 1415/2400, 1410/3800
    Note, the 2400 has has the 5mm rotor installed, stock its the 1/8" and you cant buy it with the 5mm rotor. You have to buy the 5mm rotor rebuild kit at like $54 and swap out the rotors that are identical with the 1/8" one being turned down on the end.

    Thanks for that info. I am currently running a 2s lipo with stampede tires and I am just looking for the best combo for bashing I will prob never run more than a 3s ever. My LHS said to get the 3800 and run a 3s. Not sure if that should even be an option just

    3s on the 1410 is pushing its limits and it WILL get hot. This motor simply isnt rated for a 4x4. Great for a 2WD though. Castle specifically says dont run the 3800 in a 4x4 on 3s, 2s only and geared really low like 15/54 max. Its the only motor in their chart that has the double ** 2S in 4wd chassis only, 3s in 2wd chassis with stock tires.

    I would strike the 1410/3800 from the list. Lemme guess, its all they stock? Bad advice IMO when castle goes out of their way to say 2s only on 4wd.

    If you want to run 2s-3s the 2650 is castles best option. Geared 24/50 with 2.2 tires on 2s it runs 30-35mph, perfect for short course racing. You will get more speed with the stampede tires.

    Which motor?
    The 2400 yes
    The 2650 no
    The sky is the limit with the 2650
    I had it geared at 24/50 on 3s and its on the edge of out of control. Motor barely gets warm to the touch.

    IMO there are three differences. With the 2650 you wont urge for another upgrade unless its to go sensored. It will handle pretty much anything you can throw at it with no temp worries. If you choose to gear it back down it wont be because of temps, it will be the "Holy Cow! I cant control this thing" factor.

    Second difference is cost
    retail
    1415 127.99
    1512 169.99

    If you inhabit enough B&S forums like I do you can usually get a good deal on slightly used items for a significant discount.

    Third the 2650 is a 1/8 scale buggy motor, the 2400 is a 1/10 scale truck motor.
