Nice!! Should have let us know earlier haha... Oh well. I ordered the Tarot T2D gimbal, hoping I can mount it to this batwing :) Otherwise have you considering making it large enough/holes to mount the popular gimbals out there?
Just change the settings on the GoPro.
I'm also wondering about mounting a gimbal such as the Zenmuse with these legs on a F550. I don't want the legs to obstruct the view. If they don't i'll probably order me a set :)
Download older version of the software and try to register with that. They changed the registration process in the newer versions.
