Good morning,
I am looking for tracking lights to put at the tip of the blades to see
tracking during flight. Have you heard of E-Z Track tracking lights?
according to website made on C-GOEZ They seem to be small, cheap, use only
two cells and have a feature where the centrifugal force from the blade
motion can be used to turn the LEDs on/off.
