Jay --

Some time ago there was a thread in this ng about what sort of light
aircraft on a pole ("pig on a stick") would be appropriate for your
establishment. That thread sort of bogged down...

Just for grins, go to http://www.rst-engr.com/weathervane/ and think about
making a 4x or 8x model of this thing. It is the July/August/September
Kitplanes project column device.

Note the red/green wingtip lights, the white tailfeathers light, and the red
flashing rotating beacon atop the vertical fin. While I used plain old T1
size LEDs on this little rascal for weight, we could use the moosey
stoplight size on a larger model.

I can design the electronics if you can get somebody in your neck of the
woods to do the woodwork and metalwork. I used an off-the-shelf gas engine
model airplane propeller for the model; you will have to do some thinking
about what you want to use on a larger model. Yes, the prop spins in the
slightest breeze.
