Thanks!

I figured out the retract switch is the only place on my 7 channel RX because all aux channels are in used - dual elevator and aileron servos - and I am to lazy (or is it cheap?) to break out the 8 channel RX. So much fun! With most retracts, I use the brush up to confirm gear down and locked but for this bird, I think it will be 'ignition on and hot'. At least the LED will help me keep track.
