Stuck to a measly 200ft because of lack of horizontal space.
Still got a glimpse of Monterey airport.
The main event was not knowing where North was, the resulting loss of control, & spending most of our laptop battery power troubleshooting the loss of control. Flight operations were eventually stopped by laptop battery exhaustion.
Had her go into uncontrolled flips again in manual mode but managed to regain control. If a motor gets too slow it'll stall & the ESC will shut down. Eventually it'll restart & hopefully facing up. The 12x6's are so close to their stall speed this happens all the time in manual mode.
FLAG FLYING AGAIN
SUNNYVALE HELL
The run of flying was bound to end with SUNNYVALE HELL. Either an ESC is bad, the ESC's are designed to stall at a low RPM, or she was near too many C-130's & caught a virus, but this was another total loss. She started flipping for no reason at 255ft & hit the grass upside down with the engines cut off.
Last shot before impact
Last decent shot before impact.
Last decent shot.
Interesting radar dish.
Pulverized again. Another crash with pride brought to you by U. Know. Where..
Flight recordings showed these flips happening in both directions, the ESC's looked good under the microscope. Down to PWM going below limits & putting them into safe mode.

Wait I see one next to giant super cap, Well maybe add a bigger heat sink to FET arrays? Is ESC set for low voltage cut off for 4 cells but should be 3 cells?
