Navigation Lights

[Tim]

Hi, I wonder if anyone can help me with regard to the following...

I am planning to build a radio controlled scale helicopter and I'm looking
for info on navigation and anti-collision lights; position, colour, flash
rates etc.

I appreciate the exact positioning will vary between aircraft, but can
anyone advise me of the basic CAA/FAA requirements? The two helicopters I am
considering are either a Bell 222 or Ecureil (A-Star).

Thanks,

Tim

The anticollision light is usually on the top of the vertical
fin, but can be on top or the bottom of the aircraft. There are
no hard and fast rules on color, position, flash rate, etc. The
anticollision light can be red or white; strobe or rotating
light; any placement where it can be seen.

The position lights are placed where they can best be seen;
at least one green light on the right side, a red light on the
left side, and a white light on the tail.

On the 222, the position lights are on the sponsons, and the
anticollision light is on top of the vertical fin.

On the AS350, IIRC the position lights are on the horizontal
stabilizer, and the anticollision light is on the top of the
vertical fin.

The anticollision lights vary, but strobes are becoming the
usual method, because the old Grimes rotating lights are just
too unreliable. The color is red or white, it doesn't matter.

You're welcome. And if you want to see where the position
lights on a 222 are, the Bell website has one on the home page.
