Everybody has their favorites. I've tried many things and I prefer separate switch and charge jack mounts. I like the DuBro Kwik Switch mount
http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXD664 and the Ernst Charge Receptacle
http://www3.towerhobbies.com/cgi-bin/WTI0001P?&I=LXE963 , available for most radio systems. I mount the two of them next to each other. It's a simple pull/push, on/off switch and the charge jack has a nice rubber closure to keep out the exhaust if you're old school like me.
Just my druthers. There are lots of choices.
