Set to 0 do disable this threshold.

VT_FW_QC_P:
description:
short: Quad-chute max pitch threshold
long: |-
Absolute pitch threshold for quad-chute triggering in FW mode.
Above this the vehicle will transition back to MC mode and execute behavior defined in COM_QC_ACT.
Set to 0 do disable this threshold.
type: int32
default: 0
unit: deg
min: 0
max: 180
VT_FW_QC_R:
description:
short: Quad-chute max roll threshold
long: |-
Absolute roll threshold for quad-chute triggering in FW mode.
Above this the vehicle will transition back to MC mode and execute behavior defined in COM_QC_ACT.
Set to 0 do disable this threshold.
type: int32
default: 0
unit: deg
min: 0
max: 180
VT_FW_QC_HMAX:
description:
short: Quad-chute maximum height
long: |-
Maximum height above the ground (if available, otherwise above
Home if available, otherwise above the local origin) where triggering a quad-chute is possible.
At high altitudes there is a big risk to deplete the battery and therefore crash if quad-chuting there.

VT_F_TR_OL_TM:
description:
short: Airspeed-less front transition time (open loop)
long: |-
The duration of the front transition when there is no airspeed feedback available.
When airspeed is used, transition timeout is declared if airspeed does not
reach VT_ARSP_BLEND after this time.
type: float
default: 6.0
unit: s

VT_FW_DIFTHR_EN:
description:
short: Differential thrust in forwards flight
long: |-
Enable differential thrust seperately for roll, pitch, yaw in forward (fixed-wing) mode.
The effectiveness of differential thrust around the corresponding axis can be
tuned by setting VT_FW_DIFTHR_S_R / VT_FW_DIFTHR_S_P / VT_FW_DIFTHR_S_Y.
type: bitmask
bit:
0: Yaw
1: Roll
2: Pitch
default: 0

VT_FW_DIFTHR_S_R:
description:
short: Roll differential thrust factor in forward flight
long: Differential thrust in forward flight is enabled via VT_FW_DIFTHR_EN.

VT_PITCH_MIN:
description:
short: Minimum pitch angle during hover
long: |-
Any pitch setpoint below this value is translated to a forward force by the fixed-wing forward actuation if
VT_FWD_TRHUST_EN is set.
type: float
default: 0.0
unit: deg
min: -10.0

increment: 0.1
decimal: 1
VT_LND_PITCH_MIN:
description:
short: Minimum pitch angle during hover landing
long: |-
Overrides VT_PITCH_MIN when the vehicle is in LAND mode (hovering).
During landing it can be beneficial to reduce the pitch angle to reduce the generated lift in head wind.
