Ta. It was cold alright that morning, but had no battery issues etc, and the Karma drone flew perfectly.
The grave with the poppy placed on it was a soldier who had been recovered from the ground a year or so earlier and a positive identification made and subsequent re-burial which I attended in 2017. (Photos etc on my website).
Thanks I'm going to try the lowest next just for "pix and giggles" 24 fps... i've been shooting 60fps as a default only coz i've been concentrating so much on just practice flying. I think moving forward since I will now have 5 batteries thx to @Singularitee PSA post , i will always start my missions with the 1st mission being a skills practice (thanks to @Ironspear & @James Hatch) then move into a filming mission.
