The Yokomo DPP-302V4 Drift Steering Gyro is a super high performance steering gyro that supports a wide range of needs and is perfect for beginners, high-level competitors, and everyone in between. With newly developed circuitry, this gyro offers 4 selectable modes and features the latest high-performance semiconductor chipset and programming. This helps to eliminate any undesired steering shake from gyro operation, helping to detect excessive movement and reducing the chance of unsettling the chassis. This gives the user unparalleled control over almost any surface. Designed to make fine adjustments a breeze and switch access is massively improved. The aluminum case has a crisp thin design and the beveled edge has been given a luxurious gold anodizing. The quad control system, which is a Revolutionary function, is roughly divided into two: dual gain mode and dual gain control. In dual gain mode, ASSIST (assist) and NOR (normal) can be switched by the dip switch. In the ASSIST mode, correction of the gyroscope works strongly against drivers operation and steering inputs. Allowing even total beginners to enjoy RWD drifting with ease. In NOR mode, the drivers steering operation is prioritized, making it possible for you to counter steer your chassis allowing more control over larger movements of the steering range. In dual gain control the gain can be adjusted in the range of SOFT and HARD respectively. In SOFT mode it will be easier to obtain initial front grip by suppressing the initial response of the gyro, taking away a little of the punch, making for tighter more controlled transitions. So it will be suitable for driving on smaller low grip tile and carpet track surfaces. In HARD mode, it is set for driving beginners and large-scale track layouts by increasing the initial response of the gyro. Yokomo has also added an endpoint adjustment button that allows you to set the travel of the servo through the gyro, preventing any unwanted stress on the steering system, reducing power drain and overheating your servo.
