This short little tutorial comes to us via Peter Chan, from Toronto, Canada. Peter figured out a way to bring new life to your worn out differential outdrives (especially aluminum ones), while at the same time improving efficiency and durability in your drivetrain.

"Blades" as they were coined by Schumacher RC about 10 or so years ago, are flat, half-moon shaped attachments that snap over the dogbone end of universals. The advantage of using blades is that instead of a round pin making contact with the outdrive (which is what wears it out) you have a wider, flatter piece that turns the driveshaft. The larger contact area distributes the force from the rotation over a larger area therefore decreasing wear on the outdrive. Blades also have the effect of being a tightter fit in the outdrive over the pin, which decreases slop in the drive train as well.

To complete this modification you will need a couple of stock Kyosho Universals. The stock universals can be broken down into 3 pieces; dogbone, axle and pivot. We will be using the half-moon shaped parts of the coupling on both the dog bone part and the axle part. Take some flush cutters or an X-ACTO knife and cut these pieces off the axle and the dogbone.
