The SkyRC GD-401A Drift Car Gyro is a compact, CNC-machined aluminum steering gyro designed specifically for RC drift cars, featuring a 32-bit processor paired with a high-precision MEMS gyro sensor for accurate, responsive steering correction. The package includes the gyro unit with an integrated cable for easy installation. To use the GD-401A, you'll need an RC car with a separate steering servo, a compatible receiver with a PWM signal output (50333Hz), and a power source within the 4.8V7.4V operating rangethe gyro draws only 20mA at 6V. While optimized for RWD drift applications with its 9 preset response curves, the unit also works with touring, rally, and short course vehicles; note that the transmitter/receiver system, servo, and mounting hardware are not included.
