Mini-Z Tips: Pinion Gears

The pinion gears that come with the MR-03 are crap. Once of the first things you should do is replace them with an upgrade set. The teeth on the stock Kyosho gears do not mesh properly and so they are slow and loud. With new pinions your car will be faster and use less power.

PN racing makes a set that works well, Kyosho makes as set as well (SP Pinion Gear Set Part #MZW119). Don't worry about this if you're going to swap in a ball diff, those usually come with their own pinions. But otherwise this is a must-have upgrade usually costing less than $6.
