    There are several different ways people break in motors but this video is what a lot of us use.

    how did you go with the light dash? I have not had very good results with increasing the RPM of these motors yet...

    Light Dash motors are pretty weak. I have not broken in many but 22k or so RPM seems okay. I'm sure with more work I can get one to 24k. I've made it to several semi-final races using light dashes on 3 lane tracks. It's popular here for proxy racing where a racer can't make the race but still wants to enter a car.

    ok yeah, I maxed out at 18k rpm and one less than that... Hyper Dash seems easier; running it un-broken in.
    where the Torque Tuned is spinning at 17k rpm with more torque!! I am just learning all this - so thank you.

    also, what can you get a Hyper up to?
    thanks

    One of the perks of light dashes is the lower torque so shorter jumping as the car will not have as much power going up the slope section. It's a bit different building and tuning a light dash car. You want to carry more speed through the corners and try to run zero brakes to minimize slowing of the car. It depends on the track but it can work well.

    My motors are okay.

    Torque Tuned 20k
    Light Dash 22k
    Hyper Dash 30k
    Mach Dash 35k

    I always have at least 2 of each motor at those speeds ready. Anything 1k lower than those numbers and I don't run them unless it's a practice day or my faster motor burns out and I don't have a replacement handy.

    Wow those are huge RPMs!! great work. I need to keep trying different break in methods.

    I didnt realaise you use different set ups for different motors. But it makes sense, thanks for the advice!

    Thanks, it takes a while to break in my motors but it seems to work well.

    Yeah, faster motors normally require slowing the car down in certain sections so various braking techniques. A slower motor requires less brakes. You can also adjust roller position and type to influence speed. I'm slowly working on a dedicated Light Dash car that includes certain design elements help it carry speed through the corners and slope sections.

    Is anybody using metal pinion for their engines? Are they useful? I don’t think I’ve seen anyone using them

    I dont think metal pinion are typically used. Almost everyone uses the purple plastic one

    Purple for MA and MS and the older chassis. Black or carbon for FMA and AR

    I have bad experience with the carbon pinions, they all tend to start slipping relatively quickly compared to purple.

    You can take a look a great light dash pro performance in this video:


    keep in mind that light dash is great if you pair it with a lightweight machine

    Are there real spec sheets (rpm/torque curve) for mini 4wd motors?
    I know originally mini 4wd is for young kids so 5-star rating system should be enough but then nobody would know even if they are just bullshitting and same motor buildings with just different paints...

    There is this chart which includes motor specs: https://www.tamiya.com/english/mini4wd/setupguide/motorguide.pdf

    But even the specs are so far off. a Mach Dash Pro opened from the package without anything done to it is close to 30k rpm. Clean and lube it and it will be about 31k. Break it in and 35k is pretty easy to get to. A fast Torque Tuned is 21 to 22k rpm. There are definitely differences. Though there seems to be little difference between a Hyper Dash 3 and Japan Cup versions.
