User Manual

vi) Receiver Sliders Menu that shows you the msec value and sliders for the receiver inputs - for info,
not calibrated - includes CH6 & CH7 for CPPM and Satellites
vii) Output Sliders Menu that shows you the msec value and sliders for the motor/servo outputs -
this is for info as it is not calibrated
viii) Acc Bubble Level Menu for accelerometers
vix) Gyro Bubble Level Menu for gyros (could be good for dynamic balancing)
x) Added support for Spektrum (R) Satellite and clones (See Note 1 below)
xi) Configurable accelerometer software filter in Misc Settings (See Note 4 below)
xii) New, 8.32 maths library to accomodate high gyro rates for self level
xiii) Lost model alarm. Constant alarm when the KK2.1 auto disarms. To kill alarm, either arm,
disarm or press Menu.
xiv) Error check for "no motor layout" on Safe screen.
xv) Better handling of receiver signal loss. Throttle drops to zero on roll or pitch signal loss to stop
sudden flipping.
xvi) Limited camstab offset to 0 through 100 as this is percentage travel
xvii) Selectable "motors spin on arm" (misc settings 2). This prevents the motors stopping when
flying which could help with motors that have problems starting up.
xviii) Selectable KK2.1 board offset (misc settings 2) - see Note 5 below.
xix) Support for Super Simple Gimbal (misc settings 2).
xx) Gimbal offset can be set using TX channel 6 & 7.
xxi) Added arming test to recevier test menu. Tells you when the yaw and throttle stick positions
will arm or disarm.
xx) Minimised jitter for servos connected to M7 & M8 (thanks for RC911).
xxi) Added a new Motor Layout called "Tricopter Servo M7".
xxii) Added an error counter to the SAFE screen in top left corner. You should not see anything
there. If you do, there could be something wrong with your board. Please report receiver used, new
features enabled, approx flight time and number of errors.
Changes in operation:
i) Defaults to AUX for Self Level On/Off
ii) All mixing resets to zero when you do a factory reset so you have to select a motor layout
iii) If KK2.1 autodisarms, it will buzz continuously (Lost Model Alarm) until you press Menu or arm or
disarm with TX
Note 1 (Many thanks to David Thompson of OpenAero(2) fame for this feature)
Supports Spektrum(R) satellite with Tarot cable
Tested with Spektrum AR7/8000 DSM2 satellite and Orange R100 Satellite
Causes jitter on servos so not recommended for gimbal control or tricopters (etc)
Does not work with DSMX R110X satellite - if someone wants to send me one, I'll add it (working
from V1.16S1 Pro)
Only supports 10 bit with all data in 1 frame
Only supports 7 channels
Uses Throttle input for Tarot cable
