Date Released: Jan 17 2020
Effectivity: All Alta X
This service bulletin is being issued to alert all Alta X pilots of an intermittent failure of Motor 1 upon initial startup.
Freefly has received ~5 reports of Motor 1 not starting properly in the field. Freefly has initiated an internal investigation to determine the root cause of this issue.
Some key points to convey regarding this issue:
Motor 1 is always the motor that does not start.
A reboot of the machine has cleared the issue so that normal operation can continue.
Throttling up the Alta X without motor 1 starting can cause a tip over.
We have received no report of motor failure in flight, the failure mode appears to only exist upon startup. Once a motor is spinning there is no evidence that the issue can occur.
Freefly will be issuing follow on updates as our investigation unfolds.
