If your controller is unusual, that's our problem, not yours. Nobody should have to research whether their controller works before they can play. That's true generally, and it's especially true in RC, where "my controller" might be a two-stick gamepad, a

The reference library behind Raw R/C runs to more than a thousand research papers and books, covering vehicle dynamics, tire mechanics, soil mechanics, rubber friction, scale-model similarity, solver theory, and racing AI - every one of them read, catalogued and cross-referenced, with hundreds of equations and methods extracted

Time scales with the square root of size, the same as speed does. So a maneuver that would take a real car one second takes an RC car a third of that. A slide that a full-size driver has a full second to catch, you have 320 milliseconds to

A 1/10 buggy is about 400 mm (or 15 inches) long and clears a big triple in the region of ten meters. That's twenty-five body lengths, in the air, with all four wheels off the ground - and then it does it again forty seconds later. Scale

There are two ways to simulate a suspension. The usual one in games is to work out in advance how the wheel moves relative to the chassis, boil that down to a curve, and slide the wheel along it. It's fast, it's stable, and it means

iRacing runs 360. Assetto Corsa Competizione, 400. BeamNG (the benchmark for brute-force physics) 2,000. We run 12,000. But the rate isn't the flex. What we re-solve is. Rate on its own doesn't make a simulator good - a fast loop full of bad

The usual way to make AI racer easier is to make it slower; cap its speed, cut its grip, drive it on a slower line, or quietly hand it a worse car. It works, and it produces opponents who are strangely good at some things and inexplicably hopeless at others,

On tarmac, a tire that isn't slipping isn't generating force. That's the assumption underneath essentially every road-racing tire model, and it's a good one on tarmac. On dirt it's false. A wheel rolling across loose ground is displacing material

Shock oil and pistons. Spring colors. Diff fluids front, center and rear. Ride height, droop, camber, toe, anti-squat, roll centers. Wheelbase and track width. Gearing. Battery, motor, ESC punch. Wing angle. The car in Raw R/C is assembled out of those, exactly as you'd write them
