Hello,
I have been flying my Finwing Penguin with a 3DR Pixhawk with uBlox GPS for the past 6 months or so. I typically start out in Manual, fly to a reasonable height, test out RTL, and then fly in FBWA/B as needed.
This past week I started testing out Loiter and had reasonable success initially. Unfortunately, my last flight I took off in Manual, flew up to 300 ft, and initiated a Loiter. The aircraft performed 2-3 nice circles but on one of the circles the aircraft banked very hard right, dropped the right wing and plummeted into earth (at about 58 mph) as I was fiddling with my Fatshark goggles (I caught the last second or so of the death spiral but was not able to pull the Penguin out of the dive).
Has anyone experienced anything similar and would anyone be able to assist in telling me why this occurred?
Attached is a log file from the crash. Any assistance would be greatly appreciated.
