I've tried all sorts of Cactus Receiver mods. I was supposed to post this a while ago with my Cactus Trigger Mod where you can see another trigger mod using 3.5mm mono plug. Here it is now, the easiest, simplest and most cost effective mod I've done, no drilling and glue-ing involved. Just 2 solder points and and velcro between battery compartment and receiver and its done.
I'll let the pictures do the talking...
