Hello.
I found mysterious problem on arduplane VTOL SITL.
I want to make my VTOL to hover at some point without radio controller,
for emergency situation on the sea(I will operate VTOL on ship, very far away.)
but I found no QBrake mode on current firmware.
If there is no QBrake mode, if some sensor fails at long distance, I don’t have time window to change airspeed sensor parameter. it is the sea, so QLand is also not available.
so I decided to use QRTL instead of QBrake(if I change home point I can use that to hover at some point in quad mode)
while testing the QRTL mode in SITL, I found another problem.
I set parameter “Q_RTL_MODE” to 3(Q_RTL_ALWAYS)
but if I change mode to Q_RTL, the plane seems to perform airplane mode RTL.
I looked through servo output, and quad motor doesn’t work.
because I’m on south pacific, I have very limited network connectivity.
so I can’t upload my SITL log, sorry.
