On a standard glider RC plane (the Lidi glider) that has twin motors mounted on the wings, and when one or both motors are spinning in the wrong direction, they won’t generate proper thrust. The motor spin direction depends on whether your twin-motor plane has puller (tractor) props or pusher props. Here’s how it works: […]

When a differential thrust control foam glider has the motor props spinning in the wrong direction / you mess up the LEFT & RIGHT connection / improper transmitter left and right adjustment, it will stall to spin right after you throw it. Different foam gliders and different propellation mechanisms (push VS pull) may produce entirely […]

When we talk about RC racing history, certain cars come up again and again, and the Yokomo 870C is one of them. Released in the late 1980s, this 4WD off-road buggy wasn’t just another kit—it was a statement. It marked the moment Yokomo firmly planted itself in the world of competitive RC racing, and even […]

The front body post is secured via one screw installed upside down. If this is loose and eventually dropped into the gear compartment, the front diff can be damaged…

The Kyosho Inferno series is renowned for its high-performance 1/8-scale off-road buggies, with a legacy of multiple World Championship titles since its debut in 1991. While the Inferno line primarily focuses on off-road models, Kyosho has adapted this platform for on-road applications in the past.

Due to its historic significance, the Yokomo 834B is highly sought after by vintage RC collectors. Original kits are rare, and even restored models are valuable, as they represent the early days of competitive RC off-road racing. Yokomo later released a reissue version in limited numbers, keeping its classic design while improving some components for […]

Gear ratio is a fundamental concept in RC car performance, balancing acceleration, speed, and torque. Internal Drive Ratio refers to the gear reduction inside the transmission or drivetrain before reaching the final wheels. It is determined by the car’s built-in gearing (e.g., differential and internal gearbox). Final Drive Ratio (FDR) considers both the pinion and […]

0.6 Mod is close in size to 48 pitch (imperial measurement) but not identical. They are not interchangeable. 48 pitch gears have a slightly different tooth profile, so using them with 0.6 Mod gears can lead to premature wear or damage. 0.8 Mod (or 32 Pitch) gears are larger and have thicker teeth, often used […]
