Learn about the oils, greases, and prep needed to get a gear diff running super smooth in your 1/8th scale ride. He uses an XRAY diff to demonstrate, but most of the techniques and advice are universal.
Which type of driveshaft is right for your car? Joe explains what track conditions are ideal for each, with a focus on 4WD cars.
Max Mört explains how their friction characteristics can help you decide if you should run constant-velocity driveshafts (CVDs) or universal joints in your car. He uses a 1/8 off-roader for his demos, but the physics apply to all types of RC race cars.
How best to spring into action - lighter or heavier springs? Depends on how you want to drive.
Should you use a slipper clutch or go direct drive? Don't slip up on this one.
We all know that that we have to tune our diffs, but why would you want to change the height? This quick overview explains how it impacts your car's handling.
Know the diff between your diffs - learn about 3 gear, 4 gear, ball diffs, and limited-slip diffs here.
Learn the secrets of building a smooth, leak-proof differential from a pro.
Ideally, the operation of a gear diff is a fluid situation. Read on to learn how diff fluid affects how 4WD cars apply power the ground.
Klinik RC walks us through how they build the "perfect" gear diff, that is, one that doesn't leak diff oil!
Ty walks us through how he builds ball diffs to get the best life from the diff and the most traction.
To get the most power and efficiency from your RC engine, you need to build and set your clutch correctly. Ty Tessman walks us through is process in this explainer video.
Tony Newland of Klinik RC shows in detail how to build (or rebuild) a ball diff the right way. This one goes almost 25 minutes, so grab some popcorn and get ready for some serious learnin'.
TLR's Frank Root gives an intro to adjusting a slipper clutch the right way.
Learn how to build or rebuild your 1/10th nitro on-road clutch from one of the best!
He walks you through his methods, how he approaches shimming, which greases to use, and how he marks the diff case. He demonstrates on the MBX8's diff, but most tips will apply to any 1/8th gear diffs.
