If you have spent any time in the RC hobby over the past few years, you have probably noticed a quiet revolution happening under the hoods of high-performance RC cars. The standard brushed servo motors that served the hobby faithfully for decades are increasingly being replaced by brushless servos. This is not merely marketing hype—it […]

In the world of radio-controlled models, the servo is the muscle that translates your inputs into motion. Whether you’re steering a buggy, moving control surfaces on an aircraft, or handling gear shifts on a crawler, choosing the right servo torque is critical. One common question that comes up is: when is a 13kg servo the […]

If you’ve ever shopped for RC servos, you probably noticed that Futaba servos sit at the higher end of the price spectrum. At first glance, it can feel like you’re paying way more just for a name—but there’s actually a lot that goes into it. For starters, Futaba has a long-standing reputation for precision and […]

The TD4 ball diffs are known to be disasterous. The front diff, even with the use of a metal T nut, will still have slippage problem due to poor design in steering (linkage and dog bone shaft problem). Our book on TD4 will discuss some workarounds.

The Tamiya Frog is a beloved classic in the world of 4WD buggies, but like many early RC designs, it has its quirks. One of the most talked-about issues among hobbyists is related to the front wheels and steering assembly. While the Frog was innovative for its time, the design of the front end can […]

This is a known issue with the Tamiya WT01 – when you oversteer the dog bone shaft will get stuck like this… A quick fix is to set the steering dual rate on the transmitter and reduce it by half …

With the hex adapter for the Frog, there is significant room for play. Very careful shimming must be done to fix this.

Many RC tracks have banked turns, especially in the direction that provides the most challenging layout for racers. Continuous clockwise turns can subject the tires on one side of the car to more stress and friction, leading to faster wear on those tires compared to the tires on the other side. As can be seen […]

The knuckle arm is also known as the “steering knuckle” or “hub carrier.” This part is essential for connecting the wheel to the suspension system and plays a crucial role in allowing the wheel to pivot for steering by providing a pivot point for the movement of the wheel during suspension travel. The wheel is […]

RWD vehicles may face challenges in low-traction conditions, such as snow or ice. With the weight bias towards the rear and the power delivered to the rear wheels, these vehicles can experience difficulties in maintaining traction and steering control in adverse weather. The video shows it all.
