NOTE: Have been burned to Quadcopter mode. Tested. Description: KKMulticopter V2.3 Circuit board Flight Controller V5.5 Hexa Mode For RC 6-Axle Quadcopter Multi-Copter Aircraft UFO. This is the latest v.5.5 KKmulticontroller that has been factory made and fully populated. It uses the Murata piezoelectric gyros which have been incorporated into the board design for robustness. The Yaw gyro assembly is also slot mounted for extra robustness. These gyros have proven to be the most vibration resistant of all the gyros we have tested so far. The board comes in black with a blue LED and has an on board In System Programming (ISP) header to enable easy firmware updates with a site recommended programmer. The on board Atmega168 chip gives users the extra space to load expanded firmware with higher refresh rates to enhance stability. The three adjustable potentiometers increase or decrease gyro gain for all three axle (Roll, Pitch and Yaw) and can be used to calibrate the ESCs and reverse the gyro directions if necessary during pre-flight setup. The board also has six ESC/Servo headers which allow multicopter configurations from 2 to 6 rotors. There are also headers for thee aileron, elevator, throttle and rudder connections from your RC Receiver(RX). The board comes with a 4 x 3 pin jumper cables to connect your RX to the board quickly and easily. Theres variety of firmware available for this controller, you will have load them due to your needs, only test program is loaded by default. 100% new Latest KKmulticopter controller V5.5 Board,V2.3 program
