Stick Scaling
These settings enable you to adjust the sensitivity of the transmitter stick. A higher number gives a
more sensitive response. It is used in preference to increasing the rates in your transmitter. The
default values are low for beginners that may not appreciate how sensitive the transmitter sticks can
be in controlling a multicopter.
• If you want to flip and roll, you will need to increase the Roll and Pitch values.
• Increase the Yaw value to yaw to your liking.
• Throttle is best left at 90. If you increase it too much, full throttle on the transmitter will run
the motors at maximum and leave no headroom for the PI control loop to adjust the motors
to keep it steady.
Misc. Settings 1
Various settings
• Minimum throttle – ensures all motors start at the same rate. If some motors do not start
when you arm, increase this value. This value also allows you to change the motor speed if
you have Spin on Arm enabled.
• Height Dampening – Compensates for the drop in height when the multicopter is banked in
a turn. Normally, the pilot will compensate for this dropping effect by increasing the throttle
slightly. The default is 0 (disabled).
• Height D. Limit – The percentage of motor power that can be used to apply the correction.
• Alarm 1/10 volts – When the flight battery +ve terminal is connected to the KK2.1.X battery
monitor pin, this sets the voltage alarm threshold when the buzzer sounds. If you want the
buzzer to sound at 10.2 volts or less, set this value to 102. The default is 0 (disabled).
• Servo Filter – Software filter that smooths out the control signal to servos. Set this value as
low as possible.
• Acc SW filter – Software filter in the KK2.1.X code that smooths out the accelerometer
reading. This value can be increased to mask vibrations. The default is 8 which results in a
low pass filter coefficient of 0.03 (8/256). It is best to leave it at this value.
