Guys,
Check out Digikey.com to find parts for industrial connectors. A standard sized pin such as used in the DB15 connector will handle 2 amps at 24 volts. I work in industrial automation with industrial servos and we connect and disconnect these things all the time and have very little problems with them. Generally they are far more sensitive to noise and bad connections than a typical analog connection like in our servos on our planes. You could do this all with just a couple of DB15's (standard density of course), the wires you already have on you servos. Just clip the ends off to connect to the DB15 (male or female), then connect the rest of the wire to the other side of the DB15. Just make sure the planes always have the same gender in them, or else you may find yourself in a bind. Make sure you screw the DB 15's together good before each flight.

Now, who wants to be first to do this?
