User Manual

Sensor Test
Displays the raw gyroscope and accelerometer sensor values.
• Must show "OK" when stationary.
• If it says “Not OK” when stationary, the sensor chip is faulty.
• Move the KK2.1.X around to see that the numbers change. In this case, it is fine if the
sensors start reading “Not OK”.
Sensor Max Min
Displays the maximum and minimum sensor values recoded during flight, when self level is off.
• Turn Self Level On.
• Arm and take off.
• Turn Self Level Off.
• Now fly to get the KK2.1.X to record the maximum sensor values.
• Turn Self Level On.
• Land and Disarm.
• Check results.
• It’s ok for the accelerometer values to hit their maximum values but if your gyro values
are at maximum then you should increase your Gyro (deg/sec) value in MPU6050
Settings.
ACC Calibration
Calibrates the accelerometers
• Set the multicopter level.
• Invoke the acc calibration routine.
• Do not move the multicopter during calibration.
• You will not be able to Arm the KK2.1.X until the calibration routing has been successful.
• If the calibration failed and you did not move the multicopter during calibration then you
have a faulty sensor chip.
Receiver Channel Map
If you have a CPPM, Satellite or SBus receiver, you will probably need to change the channel
mapping. The default is for Futaba receivers that have the channel order Aileron, Elevator, Throttle,
Rudder and Aux (1,2,3,4,5). Spektrum uses the order Throttle, Elevator, Aileron, Rudder, Aux
(3,2,1,4,5). You can select any channel from 1 to 8 for the mapping.
If you have a standard receiver, you can switch the inputs around. This may be useful if you have a
failed input and want to use the Aux input instead. Say the Aileron input doesn’t appear to work. In
Receiver Channel Map, change Roll to 5 and AUX to 1. Then plug the receiver Roll output to the Aux
input. To enable this feature for a standard receiver, Mode Settings, Channel Map must be set to
“Yes”.
