1. AUTO-PILOT SETTINGS [Settings about automatic flying]
1.1 *MAX-ROLL
Maximum roll angle, in degrees. This is the maximum roll angle AP can use
except in MAN mode. Increase this parameter will increase the
maneuverability
of the plane, but
a too big value will cause unstable flying or crash. Recommended value is 20~45 degrees.
1.2 *MAX PITCH-UP
Maximum pitch up angle, in degrees. This is the maximum pitch angle
AP will use except in MAN mode. A too big value maybe will result in stall or spin. Recommended
value is 15 ~35 degrees.
1.3 *MAX PITCH-DOWN
Maximum pitch down angle, in degrees. Recommended value is
10~30 degrees.
(NOTE: In STB mode AP allows slightly higher MAX-ROLL/MAX PITCH-UP/MAX PITCH-DOWN to
increase the
maneuverability
)
1.4 SAFE ALT
Safe altitude used in RTH mode, in meter/feet.
In RTH mode if the plane’s current altitude is below SAFE ALT, it will climb to SAFE ALT as soon as
possible.
If the plane’s current altitude is above SAFE ALT and distance > 500m, AP will fly to home along
the line between the current position and a point above home (the altitude of this point is SAFE
ALT). At distance < 500M from home, AP will descend to SAFE ALT at max allowed rate.
ATTENTION: WPT/ALT mode will ignore SAFE ALT setting.
1.5 *CRUISE SPEED
In kmph or mph. In auto-fly modes (CIR/ALT/WPT/RTH) AP will maintain
the speed according to this parameter. A too high value will be
inefficient
. A too low value is not
safe and will maybe cause the plane to stall. It is the pilot's own responsibility to judge a safe
cruise speed based on his own setup variables.
1.6 CRUISE THROTTLE
In percent. It's a recommended value defined by the user. For
example your plane needs 50% throttle to fly at CRUISE SPEED, please set this parameter to 50%.
The AP will refer to your recommended value but won't lock on it.
1.7 THROTTLE-P
The gain of automatic throttle control. Don't attempt to change this value.
It's for experts only.
1.8 *ROLL-P
The
gain of roll control.
With a bigger ROLL-P value AP will deflect the aileron
controlled surfaces more. A too big value may cause to oscillate in rolling.
For a stable plane such as Crosswind it should be about 10. For a very sensitive plane, especially
some flying wings, it should be about at 4-8.
1.9 ROLL-RATE
A lower value makes the plane roll smoothly but slowly. It limits the roll rate
of the plane.
1.10 *PITCH-P
The gain of pitch control. With a bigger PITCH-P value AP will deflect the
elevator controlled surfaces more. A too big value may cause to oscillate
in pitching.
1.11 PITCH-RATE
A lower value makes the plane pitch smoothly but slowly. It limits the pitch
rate of the plane.
1.12 YAW-P
The gain of yaw control. Usually yaw control is not so important as the
ROLL/PITCH. In most cases you can set it to 0
.
1.13 CRUISE-P
Cruising gain, the bigger the value, the faster the plane try to point to the
flying path. It
is the accuracy with which the plane follows the direction. Higher value will make
the plane too sensitive and fly in a snake pattern; low value will make the plane fly with an
constant error. We recommend to leave the default value.
A too big value will cause the plane to
heading left and right, result in a flight path like a snake. A too small value will cause the plane
