VERTICAL STIFFNESS
Vertical Stiffness Gain modifies the vertical stability of the ALTA 8 in Height mode.
Decrease this value if ALTA 8 experiences vertical oscillation or vibration. Increase
this value if ALTA 8 is sluggish while accelerating to a desired climb or descent rate
in Height mode.
HOLD STRENGTH
Hold Strength Gain tunes how much ALTA 8 will attempt to stay on a desired
altitude in Height Hold mode only. A higher value will result in height being held
more precisely. Too high of a value can cause ALTA 8 to overreact to winds, gusts or
turbulent air.
CLIMB RATE STRENGTH
Climb Rate Strength adjusts how much ALTA 8 will attempt to maintain a desired
climb rate. Higher values will result in a more direct feel between pilot climb or
descent commands and ALTA 8 flying behavior. However, values that are too high
may cause instability.
POSITION TUNING
Tuning position parameters will adjust how well ALTA 8 maintains a desired ground
speed or a position over the ground. Similar to attitude and height tuning, the
primary value to adjust is stiffness.
HORIZONTAL STIFFNESS
This changes the horizontal stability of ALTA 8. Higher values increase ALTA 8’s
resistance to wind gusts or turbulence from moving ALTA 8 off its target position.
Values that are too high can cause instability of ALTA 8.
HOLD STRENGTH
This adjusts how much ALTA 8 will attempt to maintain its place over a target
position. A higher value will result in position being held more precisely. If too high,
positional instability can result, causing ALTA 8 to fly past a target position.
