Update:
The Mav came with .400 and I haven't updated it. Did all the calibrations etc. Had a few short, close and low practice efforts in the garden in beginner mode and tripod (pretty windy the last 2 days) and everything seems to be hunky dory.
Absolutely loving it. Just need some better weather to venture a bit further out.
I think I will stay put on .400 as long as I don't get any issues. I am coming round to the view of 'it ain't broke - so why fix it'.......[emoji28]
