I can say it's a stable beast in windy conditions, haven't actually bothered to check the wind speed.
Where the Inspire drops its shoulder into a good wind and bounces around the M600 just sits there.
Its a pleasure to fly, I have an Inspire 1 (x3 - z3 - x5r) and a Mavic Pro. to compare it with.
Despite it's size, it is my bird of choice.
The latest Go App seems to have introduced a pile of issues from poor to loss of Video Signal to the app freezing or crashing.
Checking to see if the DBSMod guys have an antenna mod to improve signal. I installed on on my I1 ...huge improvement in video quality and control signal.
I have just fitted a Ronin-MX, but I am thinking I was better off with the z3 and x5r gimbal set-up for flight time (38 mins approx using TD48's) and ease of use.
I have tried the Litchi app on Android but it doesn't support the video out from the Ext port which the z3- x5r run on.
This is strictly an IOS option on Litchi at the moment.
The Ronin runs over the Light-bridge 2 connection, but connecting a DSLR and running it is a whole adventure on its own.
A must have is the Hex Charger ... 6 batteries charged and ready to go in about 80 minutes, but two sets minimum required realistically.
You do have to plan to go flying with it, given its size. - Think Van - Small truck etc. for moving it around.
The case ( 750 mm or 30" cube) just squeezes into my Subaru station wagon.
One thing I have noticed with the M600 is that people regard you as a serious pilot when they see the bird, not one of those pesky Drone guys the media loves to bleat on about.
I have only had one bad experience with the M600, and he was a whack job (think tin foil hat) so he doesn't count in my book.
Its supposed to be windy here over the weekend, I will try and get a bit of video of it in action beside the I1.
I hope this helps.
Cheers
