The shell adopts all metal CNC processing and surface treatmentExquisite and compact design, suitable for mini Z/Q/D/R and 1/28,1/10 Drift carHigh quality gyroscope sensor has more stable performance and longer service lifeCombined with the feedback of multi professional evaluation, the program optimization is more reasonableX, Y, Z 3-axis can be set to match more rc cars. Multiple sensitivity modes are available for more application scenarios.Dimensions: 21 x 15 x 8.5 mm(0.83 x 0.59 x 0.33inch)Working Voltage: 3.7 ~ 8.0VWeight:4gCurrent Drain: Less than 30mAOperating Temperature:-10+50Gain Mode: Normal / AVCS ModeOperating Voltage: Control SystemInput Signal: PWM(50~333Hz)/ /SUR/SXR/SHR;FUTABA S.BUS/S.BUS2Input & Output Plug: JST1.5mm (attached the signal input cable to connect with receiver)X, Y, Z three-axis selection:Press and hold SW to power on to enter the travel setting, then double-click SW to enter the axis selection, the red lightflashes twice and it will stay solid red light (default Z axis), press SW to switch to the X axis green light It flashes twice quicklyand turns on, then press it again to switch to the Y-axis, the blue light will be solid, and continue to press SW to switch to theZ-axis. If you do not operate the SW key for 5 seconds, it will automatically exit, and the gyro will automatically enter the initialization.RC Parts & Accs: For Vehicle Type: CarsUpgrade Parts/Accessories: GyroModel Number: -GYS2-V4Recommend Age: 12+yUse: Vehicles & Remote Control ToysFour-wheel Drive : Assemblagecolor:PurpleMaterial:MetalPackage Contents:1 x Racing Gyro Drift Car StabilizerOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the it in the picture a little different from the real thing.
