Since I now have an APM on my camera quadcopter, I got a Windows 8.1 tablet for mission planner. Holding it in one hand isn't smart, so I came up with this.
There's an opening on the left side to attach an OTG cable, i.e. for the 3DR Radio.
The bottom has a hole to fit a 1/4"/20 camera thread insert. I actually cracked apart a Mobius holding base to get it, and used a hot soldering iron to melt it into the hole.
The mount on the transmitter is a generic monitor mount that you can find on ebay.
Printed in PLA, 40% infill, sliced with Slic3r. It just fits on a 200mm wide printing bed.
