    aluminum motor mount

    is this necessary upgrade? I am still running stock plastic but i was wondering if aluminum would be better.... What does it help with? I am still running stock and I have no problems with it, I just always see people swap these parts out.

    my motor is 2400kv castle if that makes any difference.

    I never had a need to swap out the stock mount. I check and clean my bearings fairly often though. If I needed an additional heatsink, or had issues with bearing failures, I would swap it out.

    I suggest kings head especially with a higher torque setup. It will not flex and the bigger bearing will stay cooler and last longer. Also kingshead gives a replacement bearing so you have a spare.

    It really doesn't matter as long as its aluminum mount , just make sure to get a good quality bearing. Think about the XO-1 going 100+ mph with same size stock bearing.

    Funny, he has just about the same post in the Slash 4x4 forum. As I said there, I have the King Headz motor mount and I love it. I have used them in my past two HCG Slash 4x4 and Ultimate Edition. They remove a lot of chassis flex and the oversized bearings have worked well for me.

    If you are not pushing the stock system, a plastic one may do you... I pushed my stocker with a 3s Lipo, that lead to heat, which transferred to the bearing, which melted the plastic motor mount, which allowed the clutch and sure gear assembly to shift, which resulted in a stripped gear....

    You decide if it's right for you.

    Stripped out gear



    The main culprit, enlarged bearing mounting hole. The bearing was shot and covered with melted plastic from the mount

    Well I am planning on only running 22/50 on 2400kv. What real purpose does the Alu mount serve then ?

    Have you read above?

    1. Eliminates chassis flex

    2. Enlarged bearing equals cooler running. longer lasting parts such as spur, slipper etc..

    I like king headz but have not tried strc. I do not like the HR. Got a dud and they have zero customer service.

    Well STRC is regular bearing, would that still help it run cooler?

    is that on 3s?
    I had my stock motor mount running for more than a year on 4s without any issue or bearing failure although a slight rub from one of the slipper clutch screw back out a bit eating a good amount on the plastic.

    I've always wanted the aluminum motor mount since day one but I want the stock to put a good mileage first lol.
    with aluminum motor mount it really stiffen around that area.

    Yes, because the aluminum will act as a heat sink to the bearing and motor. Advantage being no issues with melting the plastic one which happens a lot.

    Alright what else can I do for my motor to run cooler? I have ordered a heatsink fan, and planning to purchase this.
