KiwiHC16 replied to David Tipping's discussion Flight planning in difficult terrain in IRIS
"I have some additional information.
If you set the Verify Height while you define your WP, MP could define negative altitude.
For that you need SRTM data which are normally downloaded by mission planner automatically.
I did a test with Jersey island…"

KiwiHC16 replied to David Tipping's discussion Flight planning in difficult terrain in IRIS
"To get ride of the ground simulation (issue for my tests) with SITL, I change a bit the SW.
In ardupilot/libraries/SITL folder, I edited SIM_Aircraft.cpp. To the function:
bool Aircraft::on_ground(const Vector3f &pos) const
I forced the return to 0.…"

KiwiHC16 replied to David Tipping's discussion Flight planning in difficult terrain in IRIS
"Here the result of my investigations:
- mission planner 1.3.30 by default do not accept negative numbers for WP alt.
- but if you go to the Flight Plan tab, there is a field called "Alt Warn" which is at 0. If you set it to -100 then you can set neg…"

"It s a pleasure. By investigating issues, it help me to understand and learn the ardupilot system.
I wish you good flight with the new frame. "

KiwiHC16 replied to Corrado Viettone's discussion Pixhawk fall from the sky in altitude hold mode
"I agree it's perfectly in sync with the AltHold activation. This tend to tell us that's not a physical failure (e.g. a motor loss).
We also can see that the Yaw doesn’t move (from the camera and log). The pitch is not really impacted at the beginnin…"

KiwiHC16 replied to Corrado Viettone's discussion Pixhawk fall from the sky in altitude hold mode
"This is in line with the log and video. Copter fall on the left. Pixhawk reduce motors on the right and increase on the left to come back to a stable position but probably no reaction from the motors. What I noticed this morning from the video is th…"

"By checking the motor numbers (2 and 3 are on the left and 1 and 4 on the right based on documentation), which is the opposite of the channels mentioned in the post above. Question, did the roll started before the motors difference of did the motor…"

KiwiHC16 replied to Corrado Viettone's discussion Pixhawk fall from the sky in altitude hold mode
"What we can see is that just after the AltHold, RC2out and RC3out went to the max while RC1out and RC4out when to the mean. Could you check that RC2out and RC3out are on the right of the copter and RC1out and RC4out are on the left of the copter. Th…"

KiwiHC16 replied to Corrado Viettone's discussion Pixhawk fall from the sky in altitude hold mode
"I find out that the copter didn't go to halt hold straight away from stabilized mode. It was in stabilized mode, then went to Sport and only then to HaltHold (at row 5026, then 5109, 83 rows). During the 83 rows period, you can see the pitch going d…"

"That's it. I just had the issue. I removed all possible option in the APM_Config.h and it goes into the APM. Thanks Randy."

KiwiHC16 replied to Tom Rieckhoff's discussion 9xr radio and throttle failsafe?
"Thanks for this explanation. I was still missing one point after reading it. I finally found the solution on the net. To set the 100% and more, it's not on the 9XR menu 5 (mixer menu) but in menu 6 of 11 (Limits menu).

I just tuned the FS on the D4…"
