Control board for multi- (Tricopters, Quadcopters, Hexcopters etc) so as to stabilize the during . High performance,easy and convenient to use. Updated to an incredibly sensitive 6050 MPU system making this the most stable board ever and allowing for the addition of an auto-level function. Uses signals from your radio receiver () and passes these signals to the Atmega644PA IC via the aileron, elevator, throttle and rudder inputs. this information has been processed the IC will send varying signals to the ESCs which in turn adjust the rotational speed of each motor to induce controlled (up, down, backwards, forwards, left, right, yaw). type: Flight Controller Board Built-in : Dualcopter Tricopter Y6 Quadcopter + Quadcopter X Hexcopter + Hexcopter X Octocopter + Octocopter X X8 + X8 X H8 H6 V8 V6 Aero 1S Aileron Aero 2S Aileron Wing Singlecopter 2M 2S Singlecopter 1M 4S Size Chart: IC: Atmega644 PA Gyro/: 6050MPU Inc.
