I am experiencing a maddening problem with one of my P2's. It's running 3.08 firmware, and I am using the Futaba 14SG radio, Ian Wood's profile (with one mod for Manual mode lockout) and stock receiver. For the past couple months I have been experiencing a growing rash of premature failsafe incidents. One over water nearly cost me the bird, were it not for fast and accurate boat driving as the P2 was landing in the middle of nowhere. It's happened at least a dozen times the past two months, and about 30% of my total flights it's randomly going into FS GHome mode. In a small percentage of those cases, toggling between GPS and ATTI will get it out of GHome, but most often, it no longer listens to me. Sometimes, including just now, it boots up in ATTI/FS, with flashing yellow lights. Once GPS warms up, it goes into GPS/FS, and then sometimes out of FS into normal GPS with flashing green lights. Also, possible clue, gimbal tilt no longer works once it goes into GHome, but maybe that's expected. I first thought it might be the GPS connector (based on some reading here), so last time I had the shell opened, I put a small patch of electrical tape on one side of the male connector, to firm up the connection. I also checked all physical connections, and buttoned her up. Since the problem first started, I have done deep IMU calibration, recalibrated the radio and P2, and compass dance every time I fly somewhere new. I've never had problems getting good sats, and never launch with less than 6, typically 9 to 12, and always manually set home location before launching, clear of nearby obstructions since it now seems to want to come home often. It just kicked in again less than 100m away. This is a bird that has gone 4km, so something is clearly wrong. I have the same payload as always: H3-3D, Hero3+, iOSD Mini, and ImmersionRC vTx (either 250mW or 600mW).
Possible voodoo tactics I am considering:
1) Re-binding to the radio. I confess I have no idea if there is a problem running multiple P2's from the same 14SG.
2) Downgrade to an earlier firmware, on the theory that the issue is with the latest firmware (but then why aren't others having this problem?)
3) Toggle the Failsafe setting in the Assistant to Landing then back to Go-Home and Landing (don't want to leave it in "Landing" only, for obvious reasons, including frequent flights over water)
4) Opening shell and searching for other possible connection issues
5) Re-routing antennas on legs, to get them away from possible noise sources? (Though they're in same position as stock, which has never been a problem.)
Open to any ideas any of you might have.
