Modding Mini-Z MR-03 Ball Differential (More and Faster Gear Ratios)

[@tonythehitman1]

I literally was looking at my kyosho diff sitting in my box and was like hmmm i should see if i convert this over since its a really nice diff then boom you post this video lol

Amazing! The same thought was on my mind for a long time.

Great video yet again! I have the pn ball bearing differential, though I've been having issues with the car pulling slightly to the left, and turning better to the left on throttle. I tried rebuilding it, regreasing, and adjusting the slip, but the issue remains. Is this typical for ball-bearing differentials, if not, do you have any advice? Thanks!

Thank you. There are a number of reasons why the car pulls to one side, and it's usually not due to the diff being a ball diff. There are several things I would check: (1) Check that the diff shaft is able to spin very freely on the motor mount; I found one a case where the eccentric bearing holder was somewhat bent causing binding on the shaft. With pan car designs, the left rear wheel always has some additional friction to overcome, but definitely minimize this as much as possible. (2) Make sure to leave a little gap between the left hub and the motor mount. You should be able to get a tiny bit of left-and-right play with the diff shaft. (3) Wheel nuts are not on too tight. (4) Check the balance of the motor pod, tweak as a whole for the chassis, front spring and ride height evenness, and even things like whether motor wires are creating any bias on the pod. (5) Weight distribution. Which chassis are you running?

@@sammybaka sorry for not seeing this earlier, thank you so much for the detailed response, I’ve checked points 1-3 thus far and don’t seem to be having any issues there. I am running a mr03 readyset with many PN hop up parts. I’ve noticed my body seems to not sit perfectly even on the car so I’ll take a look at the chassis balance. I noticed the issue after upgrading to a pn LCG motor pod. I will update you once I’ve played with that a bit.

Sorry but can we trade the overly dramatic music for spoken words?

I can try to add voice over in the future and see how the production will be like. Thanks for the feedback
