IOC FLYING NOTES ！！！
(1) When Multi-rotor is flying by home lock far away from you and the home point, please DO NOT
toggle the IOC switch many times quickly so as to avoid the change of home point without your
attention.
(1) Home lock flying requires that 6 or more GPS satellites are found and the aircraft is further than
10m away from the home point.
(2) If the IOC flying requirement is not satisfied, the autopilot system will quit IOC control mode.
Please be aware of the LED indicator, to know the current control mode of the autopilot system.
(1) Blinking indications of IOC are:
a) Before motors start: blink, all sticks (except throttle stick) return to center;
blink, stick(s) (except throttle stick) not at center.
b) After motors start and throttle stick is over 10% in 3 seconds: blink, all sticks
return to center; blink, stick(s) not at center.
(2) Before you do the home lock flight, you have to fly the aircraft out of the 10m range around
home point, and then flip the IOC switch to Home Lock position to fly in home lock when all the
requirements are met. If you have already toggled the IOC switch to Home Lock position when
the aircraft is still in 10m range around home point, and this is the first time you are going to fly
in home lock during the current flight, then if all the requirements are met, the main controller
will change into home lock automatically when Multi-rotor flies out the 10m range around home
point.
(1) When flying in Home Lock mode, if any of the following situations happen, then the
system will quit Home Lock flying and automatically enter Course Lock flying. The aircraft
will fly in Course Lock using the earlier forward direction.
a) The aircraft fly’s within 10m range of the home point.
b) You toggle the control mode switch to the ATTI. Mode.
c) The GPS signal becomes bad (The GPS signal LED is blinking Red twice or three
times).
(2) We suggest that you should know clearly which flight lock method you are going to fly,
and you know the locked forward direction or home point, before you switch on IOC
mode during the flight.
