Specifically, the monitor mount: http://www.quadrocopter.com/Secraft-FPV-Station-for-TX-Tray_p_1078.html and the RX tray: http://www.quadrocopter.com/Secraft-Transmitter-Tray-V1--Small_p_1069.html or http://www.quadrocopter.com/Secraft-Transmitter-Tray-V1--Large_p_1070.html Straps: http://www.quadrocopter.com/Secraft-Transmitter-Double-Shoulder-Strap_p_1072.html and this bracket since it's a heavy load: http://www.quadrocopter.com/Secraft-Large-Bracket-for-TX-Tray_p_1075.html It's a lot of crap, I know, but it's one of the better solutions for this type of thing.
If you don't need the tray but just want a monitor mount, this carbon fiber mount is a pretty good deal at $29.00 on E-Bay. Bought two, rock solid, work great, saved a boat load of cash! This seller ships fast, had them in 5 days. You'll also need a neck strap balancer. Mount: http://www.ebay.com/itm/231006279974?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 Balancer: http://www.ebay.com/itm/Hot-NECK-ST...Control_Parts_Accessories&hash=item3cc5fe1963 I wasn't paying attention to where the balancer was coming from and noticed Hong Kong after placing the order. Not a biggie to me, just passing along the info.
Andy, It bolts to the ring that the neck strap currently connects to...balances out the weight of the monitor, battery, etc through additional strap attachment points.
