Next is to test RTH function. You have to set home before take off.
If you don't set home the OSD will show N/A instead of a target distance reading. Once you
engage RTH mode in this situation, AP will load in the last HOME location and display a
warning message.
The AP will automatically set home when GPS lock to 8 satellites and more.
You can set home manually using the stick of your radio. Put CH5 and CH6 in LOW
position, hold the ELE stick in down position for 2 seconds or longer, the OSD will
prompt "
SETTING HOME?
” on the screen. Then switch CH5 to HIGH position. The
elevator of the plane will swing to indicate that SetHome operation is done. Then switch
CH5 to LOW to quit SetHome procedure.
Before you test the RTH for the first time, make sure the plane is in your sight. About 200
meter away and 60 meter high is a good position to start test. Switch to RTH mode, if
everything runs smoothly, the plane should turn to home and fly back to you. After flying
above your head it will start to circle around you, and the flight mode becomes "RTH*".
a)
If the plane turns too slowly or it is not able to maintain the cruise direction well, that
means the CRUISE-P is too small. Go to the OSD menu and increase
AUTO-PILOT
SETTINGS->CRUISE-P
1 or 2, then try again.
b)
If the plane flew oscillating on its path just like a snake, that means the
CRUISE-P
is too
big. Decrease
AUTO-PILOT SETTINGS->CRUISE-P
and try again.
c)
If the plane not able to reach the SAFE-ALT and maintain the altitude, increase
AUTOPILOT SETTINGS->ALT-P.
If the plane oscillates around the altitude, decrease
AUTOPILOT SETTINGS->ALT-P.
d)
If the plane speed is too fast or too low, please adjust these parameters:
AUTO-PILOT SETTINGS-> MIN SPEED
AUTO-PILOT SETTINGS-> MIN THROTTLE
We do not suggest to use a very low
MIN SPEED
setting at the beginning.
Please set a proper
MIN THROTTLE
value so that the plane is able to maintain the
necessary air speed even when it flew to downwind. A very low
MIN THROTTLE
value
may cause to stall when the plane flying to downwind. Because it satisfies the
MIN
SPEED
but may not have enough air speed in this case.
We will produce air-speed sensor soon to avoid the plane to stall.
After set up the plane following the above steps you can have fun with your plane now.
For more details about setting, please refer to

How to enter the OSD menu
THR, CH5 and CH6 in LOW, move ELE to the bottom-right corner, wait for 2 seconds or longer
until the OSD prompts “Enter menu?”. Then switch the CH5 to HIGH to enter OSD menu mode.
The menu will appear on the black background. You don't even need a camera connected.
