I broke the tiny micro HDMI male to male cable that came with the Walkera G-3S gimbal and couldn't source a replacement. Email to Walkera has gone unanswered so far. So I took that as an excuse to get a DJI Lightbridge, because you can actually buy their replacement HDMI cable!

It's pretty great so far. I have it working with my Taranis and Galaxy Note 4. It mounted well in the frame. Still have to do a "signal diagnostic" check. I will do that with and without the 5.8GHz pilot cam active. The 5.8GHz antenna is kinda close to one of the LB's antennas.

The Walkera QR X800 barely limps into the air with a Sony RX100 and Walkera G-3S gimbal. So I upgraded the motors and props to GREAT effect. Here are the parts I used:

OR if you want to go all spendy and get great efficiency (see their chart, shown to be pretty accurate by a guy testing on YT):
(2) Sets of Foxtech Supreme C/F Propeller(18x6.1)

(4) 3/4" Hose clamps... really... they work great!

I couldn't find motor mounts that would fit Walkera's non-standard 18mm arms. Fortunately those arms have an inner diameter of 16mm, perfect for slipping a 16mm CF arm into. Leave enough out to attach the motor mounts. Use the pipe clamps to secure the 16mm inside the 18mm tubes. The end of the 18mm tubes have a great shape to allow the pipe clamps to really compress the outer 18mm against the inner 16mm.

Two of my 16mm tubes wouldn't slide all the way in their 18mm hosts, so I knocked it in as far as I felt safe with a hammer and then...Continue Reading
