Decent price for an actuator, but we've bought them for as little as 
$3.50 from other places.

Nice price for a transmitter/receiver, but I'm not sure if it will 
operate servos directly.  According to the minimal specs at

http://www.vexlabs.com/vex-robotics-transmitter-receiver-add-on-kit.shtml

it has an RJ-10 cable that connects the receiver to a "Vex Micro 
Controller", which is probably used to operate the servos.  If we can 
find some specifications for that cable, we can probably modify the C6C 
to support that receiver as an input device.  It's probably a fairly 
simple serial protocol.  But, according to the answers from the Vex 
engineers posted on that site the details are "proprietary" which means 
that they won't be very helpful.  Maybe that's why they have to dump 
their products well below retail value on the surplus market!!!

Also, it only has crystals for channel 89, so even with a solution to 
the protocol problem, a source for alternative channels is needed.
