Speed control: Sets the gain to maintain the actual aircraft speed and
the target speed. The higher the gain, the faster the aircraft will react
to changes in actual aircraft speed.
Speed damping: sets the amount of ‗buffer‘ for throttle change initiation. If there is a change in
flying speed, that change must exceed the damping value before throttle is reduced or increased.
Generally, you can change the above settings during cruise flight.
Warning: We suggest not to increase the settings too high, it may cause very unusual flying behavior
and may result in damage of your aircraft due to excessive throttling.
The normal setting is around 10-40.
Auto Take Off
1. The auto take-off feature is designed mainly for hand launched planes.
2. Please select a fairly stable plane if auto take-off is to be used.
3. The Auto Take-off should not be attempted unless you have completed setting up Auto
Balance mode and fill in the Navigation parameters.
4. Critical Parameter Examples:

Set the climb pitching angle for auto take-off.

Set the climbing Groundspeed for auto take-off

Set a return point and the altitude for return point (default is 200 meters).

Mission: Circle over home-point after auto take-off.
Auto take off procedure
1. After located by the GPS, click ―Auto take off‖ in the GCS.
2. When the menu button background color turn to green, set Channel 6 switch to the position
of ―Return to home‖
3. Set the throttle level to the position for taking off.
4. Throw out the plane in a level and straight way.
5. You will notice the plane will fly in a straight line first.
6. When the autopilot detects groundspeed has increased at a value needed for climbing, the
plane will climb up to approximately 50m altitude.
7. Upon reaching 50 meter altitude, the auto take off Procedure is over. Control is automatically
transferred back to your RC transmitter.
8. However, the plane will still continue flying autonomously, gradually circling and increasing
height to 200 meters over the home-point. At this height, the aircraft will hold altitude.
9. Remember that if you had done any adjustments to the Flight Parameters (e.g. Pitch and Roll
stability), remember to click ―Permanents storage‖ to store your settings in the Autopilot
RAM. Failure to save these settings before powering OFF will result in lost of all
adjustments done.
This manual is just a guideline to help you set up your aircraft for autonomous flight.
