blinking.
2 Please avoid using WKH system in the following areas,
where will GPS signal is most likely blocked:
Urban area with crowded buildings
Tunnels
Under bridges
3 Make sure the attitude of helicopter is in good condition,

transmitter, WKH and all the devices on your helicopter;
STEP3: Turn on the transmitter first;
STEP4: Power on WKH and all the rest of electric device on
helicopter, except brushless motor controller;

system start-up has failed. You will need to place your
helicopter horizontally and power on again. See Appendix
for details about LED indicator;
STEP6: You may find red LED blinking, indicating that WKH is
getting GPS satellite signal, please wait until red LED is off,
meaning WKH have found more than 7 GPS satellites, and
that it can work in its best condition. See Appendix for
details about LED indicator;
STEP7: Slide the control mode switch on your transmitter to make
sure it is working properly. Check it with LED indicator to
specify the current working mode for WKH. See Appendix

2 Switch to GPS Atti. or Atti. Mode and wait until the
speed of main rotor is stable ;
3 Requiring only pushing the throttle (collective pitch) stick
gently to take-off the helicopter, autopilot system will be
in charge of the cyclic pitch/roll stabilization.
Semi-Auto Landing
In GPS Atti. or Atti. Mode, with throttle (collective pitch) stick
operation only, descend the helicopter and hold throttle stick
on lowest position until the engine or electric motor is cutoff
automatically. This throttle idle or shut-down in Auto mode
when collective is lowest stick position only applies having
this option.
1 With this option, MC will perform in GPS Atti.
Or Atti. Mode for both takeoff and landing.
