User Manual

Hold buttons 2&3 on power up to enter binding mode (button 3 for DSMX)
If you switch between CPPM, Sat or normal receivers, you have to power cycle the KK2.1
Debug lists 16 frame bytes from satellite - you'll know if there are 2 frames of data (so bind again).
KK2.1 Settings: -
You will need to set "Sat or CPPM" to "Yes" in Mode Settings
You will need to assign the channels correctly in "Receiver Channel Map" (previously Sat-CPPM
Channels) as A=2,E=3,T=1,R=4,Aux=5
If using TX for gimbal control, CH6 & Ch7 are assigned
Note 2
No need to change P&I or stick scaling settings when changing gyro rate now.
Note 3 (MPU Settings)
Set gyro rate and acc rate high if you like acro and low if you like sedate/fpv flying
If you exceed the gyro rate when flying, it will spin/flip/roll really fast.
Set the filter to a lower value to filter out vibrations in your frame - try to leave on default if you can
as too low slows the control loop down and results in oscillations.
Note 4 (Acc Software Filter)
Default is 8. Best to leave this as it is.
Note 5 (Board Offset)
This allows you compensate for the KK2.1 not facing forward.
Normal operation is with the KK pointing in the direction of flight and Board Offset 0.
Say you have a +Quad setup and want to change to an XQuad but can't rotate the KK board.
No problem, leave the board and motor connections as they are and select Board Offset -45.
You must also change the Motor Layout to XQuad.
Say you have an XQuad setup and want to change to a +Quad but can't rotate the KK board.
No problem, leave the board and motor connections as they are and select Board Offset +45.
You must also change the Motor Layout to +Quad.
Note 6 (Switchable SS & PI in flight)
In the Profiles menu option, if you select Yes for "Switch SS & PI" you will fly with Profile 1 when Self
Level is switched off and when you switch Self Level On, you will switch in Profile 2's Stick Scaling
and PI gains and limit (including Self Level) settings.
