An update to my previous R/C aircraft external lighting circuit. Includes 2 each of port, starboard and tail position lights as well as 2 anti collision (strobe) lights and a landing light and a search light.
I've been trying to come up with an external lighting solution for a custom build, scale, R/C helicopter and I believe this is it.
The anti collision lights meet the federal aviation regulations requirement for flash frequency not less than 40 flashes per minute and not greater than 100 flashes per minute.
