If it is just for travelling/fun and not commercial, then in addition to the things mentioned above I would suggest an assortment of ND Filters for differing light conditions and always have some lens cleaning fluid/microfibre cloths with you.
Spare Memory cards
A good sunshade for the tablet(s) (especially if you are travelling to sunny countries)!
Two spare props (one CW and one CW)
A small hex screwdriver to fit the screws on the Inspire.
That should do you for holiday travels.
Thanks for the replies. (to the hijacked thread -> sorry)
You know, I didn't even consider the battery charger.
I was more focused on breakable items on the Inspire itself.
Very good point, I'll be sure to scoop a spare charger.
I already know to have appropriate tools to take apart stuff to a certain extent.
Have several RC-hoods depending on what iPad I happen to want to use.
Polar Pro 6 pack filters, several batteries, couple sets of 1345Ts, microfiber and lens solution.
But these are all just common things to actually use the Inspire.
I was thinking like battery tray. Its always the first thing to go in a semi-hard landing.
I don't know if that is true or not, but that is kind of what I was looking to the longer term owners to chime in and offer experiences with.
Whats the most likely thing to get messed up.
Are the gimbal motors on the X5 as prone to separation as the silly things are on the phantom 3s.
Like my original comment, I'm ok dropping a couple hundred on a X3 camera (as a spare) if the X5 has been shown to be problematic.
If its rock solid unless you drop the bird from 400ft, then I'll save my money.
And in my case, 90% of my flight time (while south) will be out over salt water.
So if I drop it there, might just as well save the carbon fiber bits for someone, and toss the rest. :-(
