http://www.endurance-rc.com/pctx.html You connect to your radio via buddy port and can control it from your PC. The neatest feature is that it can control 9 channels using a 4 channel transmitter (and 9 channel receiver). Apparently everyone uses the same hardware across their line of tx's. There's also some awesome joystick software that they sell. You can then control your boat via joystick with the above radio interface. http://www.endurance-rc.com/servocommander.html -iamscottym
Good Find on the PCT, might have to pick one of those up. Not really sure for what, but it'd be cool.
