This is the rig, built with parts sourced from:
Brooks Leffler (gears, frame, picavet)
Dunehaven (radio transcievers)
Gentles (Pan control)
Hobbystores (LiPo gear)
My local B&Q (nuts, bolts and washers)
Drew's hardware (steel drills in imperial sizes)
Maplin's (boxes, grommits, soldering stuff)
This is the Dunehaven control, with still video display.
And, of course, the image in the display (taken with the rig hanging in the back garden...)
