1) Even after the ST16s date and time are set (in the tablet section) and working correctly, the E90 file times are not correct, although the date is usually OK.
2) During a Gimbal calibration, the Gimbal may "stick" for no apparent reason. The Owners Manual suggests "nudging" it a bit. This works, and the Gimbal and Camera operations are not affected.
3) On initial startups, if the ST16s E90 video does not appear or if it is lost (screen says "Waiting for Video") and does not reappear, turn the craft back off, then turn off the ST16s. After 15 seconds, restart the ST16s, let it boot to the acquisition screen, then turn on the craft again.
These "bugs" will be corrected in future updates.
