  1. I run a Superstock BZ with an Mtronics 20T ESC and the 20T pinon, std Acoms servo, GPM shocks, usually running a 4500 battery but sometimes lower. Shocks are a bit soft but it's great on flattish gravel/dirt. Plenty of dust thrown up from a standing start!

    Lost one of the step screws from the front knuckle, wondered why the wheel was at a funny angle...

    does it wheelie? mine with a 1500 cheap battery wheelies on the carpet on a full charge and stock motor, but i would like to wheelie on the street to

  2. Probably you land after a jump at full trottle and when the wheels touched the ground again the motor torque did strip the gear.

    No slippery clutch and a torquey motor and this is the result.

    Max

    when i jump, i let go of the trottle compleatly

    I don't know what to tell you now... I've had half a dozen of those gearboxes over the years and never stripped anything, and I've done some truly stupid things to them. If anything breaks, it's usually the axle tubes where they attach to the housing.

    Maybe it's overheating the motor, and the excess heat is causing the gear to weaken or softening the motor mount and changing the gear mesh. Old motors weren't nearly as efficient as newer ones, and heat was sometimes a problem, especially if the motor is worn. That's about all I can think of. Try a newer motor, and see if it holds up better. There are a lot of cheap mod motors around that will outperform "vintage" motors.

    the motor runs cold

  3. Do you have ball bearings in it? If you're still using bushings, they could be worn enough to mess up the gear mesh.

    If you have bearings, it almost has to be something assembled wrong and not lining up. You should be able to run just about anything short of a small-block Chevy in that gearbox and not strip anything.

    Maybe if you post a picture of the stripped gear, we can point you in the right direction.

    im running full ball berings, idk how to post pics, but the gear is missing 3 teeth

    Is the pinion gear worn? As it wears it creates sharp points that will just rip into the spur gear. And if there are the kit plastic bushings in there instead of bearings if they are worn they will move the gears apart and again damage the gear teeth.

    the pinon looks brand new

    Nothing really to add other than the gearbox should take a lot more punishment.

    I've been running mine with a castle creations brushless motor that revs at over 45,000 rpm and the gearbox sounds sweet - and is working fine. Before that I had a 19 turn motor installed, again with no issues.

    Could it be a fault with the gear box casing, or motor mount plate?

    how would i tell if it is a fault in the gear box, or motor mount plate

  4. i keep stripping this gear in my tamiya lunchbox, the first one had about 50 runs with the stock motor, and then i felt the need for more power. the motor i put in it was a yokomo twisters motor, and on the first gear, i got 5 runs, and then i gave it full trottle from a dead stop, and it partially lifted the fron end, and just stoped, then the same thing happened on the second gear, but this time it was on the 10th run.

    is their a solution, im tired of stripping gears. here is a video of my lunchbox with that motor in it.
