From 00:40 to 00:50 it sure looks like your tribrach extends well-off the edge of the tripod on that setup....are you a land surveyor? I'm guessing no.....
I am. Good spotting and thanks for going through the whole video without skipping As long as the setup is centred to the mark that’s all the matters. I notice you are not a content producer, try it and let me know how you do while you have to film, do your normal tasks and at the same time interacting with clients and your team
Piks 09 we have 3 sets of batteries (4000mAh x6) and our payload is Sony a7r camera. Each set can only fly 12min max in favourable condition ,wind speed less than 15km/hr, to land it safely without pushing the batteries limit. 11 batteries is great but you need to consider the manufacturer flight time limit as it may overheat.
