Thanks for the feedback guys. I guess I should have added more 'colour' to my initial post.
I have a couple of years experience playing with a DJI F550 with a Go Pro in a brushless gimbal. I'm now looking to start an AV business focusing on TV, commercial, property and events. The Skyjib option comes with a Zenmuse Z15 gimbal for the GH-3, but that will be changed to a GH-4 gimbal. The controller is Wookong and everything else is Droidworx. It's over 1 year old (non-folding frame) but very well built and with a lot of additional modifications to make it a better platform.
The S900 option would be a brand new build with Z15 gimbal for GH-4, A2 flight controller and other bits and pieces like iOSD, etc.
I may need to pack it down and take it abroad.
Hope that helps fill in the gaps a bit
Oh, and I'm in the UK, so the fact that the S900 can come in JUST under 7kg and the Skyjib weighs 9.5kg is a consideration.
Thanks,
Dom.
