I have been experimenting more by running the GCS and aircraft outside at home. I have set the flight plan so that there are four waypoints around the outline of my garden :) The aircraft should fly a circuit around them. However, when I power on the autopilot and look at the GCS, the indicated position of the aircraft is nowhere near my house.
I set the location of my house using google earth, and the google map tiles in the GCS confirm the correct location.
When I center the map on the aircraft and put my mouse over it, it indicates the position: -0.000015, 172.511261 which is somewhere in the ocean NE of Australia.
The park I fly at is at: -27.520945, 152.960962
I am just down the road from the park.
Can any of you explain what could be causing this wrong indication of position?
The wrong indicated position would explain why the autopilot is entering into 'HOME' mode - It thinks that it is exceeding the "Max dist from home" in the flight plan.
I bought my Tiny v2.11 as a bundle from PPZUAV, so the bootloader and tunnel were already done for me. He is located in America, so do I need to reconfigure anything for the southern hemisphere?

I have sorted out all of the issues from my other thread, and now the hardware is all connected properly, the power supply is no longer heating up, and the modems are talking to each other.
I have had a few flights, and the GCS data is all accurate - (Altitude, attitude, airspeed, batt voltage etc.)
However, every time I activate 'Auto 1' or 'Auto 2', after a few seconds the GCS shows that the autopilot is changing to 'HOME' mode. When this happens though, the plane does not try to fly back to and circle around home, but moves the servos to their preset failsafe positions.
Double clicking on the 'HOME' box to cause the autopilot to revert back to 'AUTO2' mode does not have any effect.
This problem only happens when the autopilot thinks that the plane is flying. If the 'launch' mode is set to '0', then 'AUTO2' works, but as soon as 'launch' is set to '1', the 'takeoff' button pressed, or 'AUTO2' activated during flight, then it switches to 'HOME' mode.
What could be causing the autopilot to switch to 'HOME' mode?
- A 3D GPS fix is successful
- The indicated battery voltage is correct, and is not falling below the critical or catastrophic levels.
- The RC link is strong and is not failing, and the datalink seems to be working both ways.
- The "max distance from home" in the flight plan is set to 1000 - more than enough. The aircraft is within this boundary when 'HOME' mode is activating.
Any ideas on what could be causing this would be appreciated.
