Product name:RadioLink Byme-DB Flight Controller Built-in Gyroscope for Delta Wing Micro Fixed Wing Paper Plane J10 SU27 F22 Precise details: Specifications: Brand Name: RadioLink Item Name: Byme-DB Dimension: 29*25.1*9.1mm (1.14'' x 0.99'' x 0.36'') Weight (With wires): 3.6g(0.13oz) Channel Quantity: 7 channels Integrated Sensor: three-axis gyroscope and three-axis acceleration sensor Signal Supported: SBUS/PPM Input Voltage: 5-6V Operating Current: 25±2mA Flight Modes: Stabilize Mode, Gyro Mode, and Manual Mode Channel for Flight Mode Switch: the fifth channel Channel for Throttle Cut: the seventh channel Models Compatible: Applicable to all model airplanes with mixed elevator/aileron controls including delta wing, paper plane, J10, traditional SU27 and the SU27 with rudder servo, F22 Transmitters Compatible: All the transmitters with SBUS/PPM signal output Socket Specifications: CH1, CH2 and CH4 are 3P SH1.00 sockets; the receiver connect socket is 3P PH1.25 socket; CH3 is a 3P 2.54mm Dupont Head. Features: Applicable for Multiple Models: Applicable to all model airplanes with mixed elevator and aileron controls including delta wing, paper plane, J10, traditional SU27, and the SU27 with rudder servo, F22. Flight Controller Assist Enhance Stability: Three-axis gyroscope and three-axis acceleration sensor combined with the full attitude algorithm, control algorithm, and digital filter make the airplane with the flight controller Byme-DB easy to change from Modes of Stabilize Mode/Gyro Mode/Manual Mode. Beginners can start with the Stabilize Mode and quickly master it even on the first flight. Three Flight Modes: Stabilize Mode, Gyro Mode, and Manual Mode. Both beginners and professional pilots can enjoy the fun of flight. PID AutoTune: Byme-DB continues to optimize the optimal PID parameters based on Byme-D. The fourth channel output is used for a delta wing with rudders, etc. No need for parameter adjustment. Only the flight control mode switch and flight controller calibration need to be set when the first wiring. Package Included: 1x Byme-DB Flight Controller 1x Byme-DB connection to Receiver 1x Double-sided Adhesive Tape 1x Packing Bag
