Don't you have a single servo kicking around somewhere?
And if you did have an LED (and a battery, for that matter), wouldn't
that qualify as having `something other than the transmitter?'
An LED between the signal and ground pins might light up when it's
receiving a signal, and it might even light up brighter when the stick
for that channel is all the way one way, and dimmer if it's the other
However, it might also light up if there's no signal (I don't know of
the AR6100 sends signals to the servos when it's not receiving one or
not) and it might not light up at all (I'm not sure what the voltage
out is on the signal line.) And it might burn up if the signal line
voltage is too high.
Really, a single servo is just the thing for testing RXs. A LED might
do something for you, but a servo will tell you a lot more. If you
want to get fancy, this works nicely too --
(it can drive a servo, and can tell you what the RX is telling a servo
to do) but it's overkill for just seeing if a RX is working.
