I found the error:

setVirtualStickModeEnabled() failed: The aircraft is starting the motor(243)

will add a retry.

Even when retrying for minutes, sometimes it gets stuck throwing this other message:

setVirtualStickModeEnabled() failed (will retry): The aircraft is taking off(240)

(after the aircraft already took off)
