Warren Purnell replied to Warren Purnell's discussion Red Boxes - Mission Planner
"That makes sense but that command wasn't given at that point of the Auto mission. Unless someone else comes up with something different it'll give me somewhere to start working it out. I'd have thought the square would have been elongated to account…"

Warren Purnell replied to Warren Purnell's discussion Copter yaw orientation changes when Modes changed in ArduCopter User Group
"Thanks but no chance. The Copter flys OK in Stabilse until it been in say Loiter then switching back to Stabilise is when the problem presents. Copter take off is facing directly away from me and not offset."

After flying in and switching back out of a GPS controlled flight mode back into Stabilise the Copter's yaw direction is 45 degrees off. eg. Copter facing directly away from me, if I pull the TX stick straight back the Copter will head 45 degrees…

Warren Purnell replied to Thomas Stanley-Jones's discussion Sync Images of Canon Cameras in Terrain/Surface Mapping
"I probably can't help past this suggestion. I'd make sure the cameras are in complete Manual Mode and the focus also Manual. The varying delays may be the cameras working out their settings & focus etc. before triggering."

Warren Purnell replied to weiqiang's discussion How can I using copter measure wind direction and wind velocity? in ArduCopter User Group
"I believe the information you are seeking is already available in Mission Planner.
You can simply select the flight data you want to view as a Field"

Warren Purnell replied to xoltri's discussion Pixhawk causing motor sync issues.
"My Hex dumped in a week ago while doing Auto Tune and having Logging Default + IMU. Motors just seemed to stop after several tune oscillation sequences. I've looked at the Logs and it seems the Pixhawk just stopped sending signals to the motors. I'm…"

Warren Purnell replied to Mohamed Abdelkader Zahana's discussion Auto Center Line tracking during Auto Takeoff
"I believe the RC Jet guys have been using Gyros to keep their planes straight on takeoff. Not sure if they link the rudder & front wheel on the same channel but would guess so.
Is this what you are doing but throught the APM?"

"On earlier versions than 3.01 Sonar for me was absolutely perfect. Once using 3.01 Sonar exhibited issues as described in the post.
On the bench I am getting accurate readings. In flight up & down with motors cutting out etc.
I've added all the…"

Warren Purnell replied to Nhat Quang Luong's discussion AC3.1 rc5 yaw issue
"I'm not sure how the AHRS values are derived and in the parameter list? If its from aan APM setup routine then maybe not a bug. If it arrives in firmware updates then it needs to be sorted.
Since manually zeroing the values my quad behaves but I've…"
