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.
Max Mört explains the effects of anti-squat, kick-up, pro-dive, and pro-squat on RC car handling (please note: "kick-up" and "pro-lift" are the same.)
Max covers everything you need to know about shock tuning with a focus on off-road racing, including linear vs progressive vs dual-rate springs, the effect of lighter or stiffer springs and how the springs affect your handling over the bumps.
Max goes deep on aerodynamics in this great three-part series covering the physics of aerodynamics, the evolution of aero tuning, and current best practices in choosing bodies and wings and determining how to trim and mount them for optimal handling when off-road racing.
Team Associated provides a summary of shock pistons and how they affect handling, so you can figure out if you should use flat, tapered, or thin pistons.
See Adam Drake explain how to tune your car's handling using sway bars
Max Mört takes us through these fundamental settings, and why they do what they do.
Comprehensive setup guide for off-road cars including explanations of settings, instructions on how to measure settings properly, and how to fix various handling problems.
Comprehensive but concise guide to all aspects of setups, focused on off-road, by Scott Guyatt
Alex Hagberg explains how to prep an RC car for racing in the rain. Many of the tips are relevant for all car classes (how to protect your radio equipment, ESC, wiring, and motor), but the setup tips (flex, camber, etc) are focused on on-road touring cars.
Everyone's favorite Aussie gearhead explains the fundamentals of weight transfer in racing and how it can be used to increase traction or change the front-to-rear relative traction while cornering. In Part 2, he covers roll center and how it contributes to cornering relative to shock springs and shock oil & pistons. A must watch for all tuners!
Adam Drake explains why you might want to glue your 1/8 foam tire inserts to the rim, and how to do so properly.
Rajaa111 explains the ins and outs of clutches for nitro cars, and how you can choose whether you want to go with a 3-shoe or a 4-shoe clutch.
Max Mört goes in depth on anti-roll (sway) bars, explaining how they affect handling for off-road cars, how to choose thicker or thinner bars, how the anti-roll bar affects the car over jumps, how important it is in comparison with other settings, and how ARBs interact with your wheelbase and driveshaft choices.
Ty explains the various shock types, how they affect rebound, and how shock rebound is used in tuning 1/8 scale off-road cars.
Ty Tessman shares off his secrets for ensuring that his car's ride height is exactly where he wants it
This is the best explainer we've seen on roll center yet - check out these great videos from Max Mört that get into the racing physics of why roll center does what it does. He focuses on off-road, but the principles work across all types of racing. Oh, and get comfy and make some popcorn - these two videos clock in at over 27 minutes.
TLR's Frank Root explains the basics of setting ride height with a focus on 1/10th scale 2WD, but it's applicable to any off-roader.
Max Mört gives a great, in-depth explanation of how wheelbase adjustments affect off-road RC cars and how to use it in your tuning to optimize weight transfer and turning ability.
