I posted this in the ArduPlane section and the users group and got no response so I figure Ill try here:
I installed a Hitec Optima 7 Rx into my plane and reprogrammed the FS settings. I want the failsafe to kick in in the manual modes but not in Auto mode. Using the 2.40 firmware, I have GCS, short failsafe, and long failsafe set to 0. I have THR_FAILSAFE set to 1. The failsafe works as planned in manual modes but it also puts the plane into Circle->RTL in Auto mode which I dont want. How can I fix this?
Do you want to fly out of your radio range?
I think it is not a good idea. Don't do it. ;)
Thats not an answer.
According to the wiki, which is out of date, there should be an option to have Auto modes ignore the failsafe. (http://code.google.com/p/ardupilot-mega/wiki/Failsafe)
For Auto and Loiter modes you have a choice (through the configuration) of if they will be affected by the failsafe or not. If so then the mode is switched to RTL. For the lower modes (Manual through FBW-B) the mode is switched to Circle for short failsafe and then switched to RTL for long failsafe. For short failsafe the mode is returned to the original mode if signal is restored, but for long failsafe the mode will remain RTL until you change it.
Ok. But remember; it is not a good idea.
