If I buy a trigger like this one. What is the easiest way to modify it so I can trigger it remotely when flying my heli? My receiver is a RD10S SYNTH. And my radio is a JR PCM 9X II SYNTH.

The trigger is for my KM D5D

I mounted a servo and the trigger too my mount and then just drilled a hole in the button of the trigger pushed some wire in there and bent the wire back to the servo. It worked mint, use your imagination you get it to work no worries

I've built my own electronic switch with opto isolated outputs. Works fine with any Rx. I belive that Angelos at http://www.spartan-rc.co.uk has something similar for sale.

When cutting and adapting to e-switch, make sure you use a Deans or similar plug. Allows you to plug into different mounts, etc. and also still be used as a remote trigger for your camera when tripod mounted.

Lots of money to butcher and render trigger unit useless

PS...looks a lot like a Minolta unit??

Most of these remote triggers are all the same, regardless of camera brand. They either carry 2 or 3 wires, open up your remote and have a look, the operation is very simple. Number 3 wire connects to number 2 wire, the camera focusses, like pressing half way on the shutter button. Then when wires 2 and 3 connect to wire one, the camera takes a photo. Theres no voltage involved in this process, if you had the camera pre focussed, you could just connect wires 1 and 3 and a photo would be taken. So instead of using a servo and the the remote itself, you could just chop the remote off, use the output from the receiver to activate these connections. Not too sure but you may need to include a small circuit that takes the receiver signal and converts it to close one circuit to autofocus, then close a second circuit to take a photo.

In the electronic switch that I made I have two functions. First is a "one shot" switch and the the second is a "continous shot" switch with variable time between shots (usually I use 4 seconds). Both ways I first autofocus for about 0.5 seconds and then trigger the shutter.

I use a ON-OFF-(ON) switch on my Tx for the different functions. I use the "countinous shot" function even when I have a cameraman with me. This way the cameraman can focus on pointing the camera. And with a 4Gb CF-card in my Canon 20D it take some time before the card is full even when I shot RAW.
