Is the sequencer active while in test fly mode? I took a flight yesterday and my gear did not retract, it may be the servo but I didn't see the door trying to close either. On the ground all worked fine, very odd issue I'm troubleshooting right now. I grounded the plane for now, going to take the servo out and test w/a different servo.
Note: plz add v6 to the drop down "Softwarerevision Mercury SRS" above, only up to v5 is available when filling out the form. just an FYI.
