This may sound like a dumb question, but has anyone ever hooked up a LED bulb to the on/off switch to indicate when the switch is on? Is it possible to do this? and if it is do you need something to reduce the voltage? I was looking for something simple to indicate when the switch is on.

probaly could be done but if the servos are moving you will know it's on.how well it shows up in bright sunlight could be another issue.why bother

Ad a Voltwatch [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXHDJ2&P=ML]Voltwatch[/link] this will give you your battery valtage when the switch is on.

Yup, you can get one here...

There is one version that monitors for radio and switch problems too.
