Week ago I received Typhoon H Pro version so I am still learning. Because manual is not saying about some things, I hope someone can answer me on this: 1. Beside microSD card slot on the CGO3+ camera, there is this micro USB slot , on the camera. What is it for ? 2. Video is splitted into 5 minutes. Can we change that somewhere in the settings 3. RealSense obstacle avoidance...is this working in all modes SMART, ANGLE and HOME ? 4. What battery voltage should be when fully charged ? 5. I read that it is best to land when voltage is 14.7 V. I did that but right after landing , voltage showed 15.1 V. So I am not sure what is true. And I think battery bar was like 3 bars, maybe between 2 and 3 bars when voltage showed about 14.9 V. So if I am guided by the bars it looks like battery is no more than 50% empty. Any advice about that ? 6. What about that battery storage. - if battery is fully charged and I am not flying in next 5 days, is battery going to be discharged slightly in this 5 days ? - to what voltage I have to discharge battery for storage and how long it can stay that way ? Do I have to charge it periodicaly if not in use ? 7. In manual it is said that for the fully discharged battery it should take about 2.5 hourse to charge. But what is fully discharged and not overdischarged battery ? I was charching battery which was about 14.8 V and it was charged in about 1 hour. 8. ST16 can be only charged via this USB cable 9. Videos recorder on the microSD card in CGO3+ camera are by default recorded to the ST16 as well or there is a setting that can disable that ? 10. What are these numbers on the upper screen, in a curved line ? 11. I can't find where I could change video recording format. I see it can only record in MP4. Am I missing something ? Thanks !
