just got back from flying here at night, although mine is only an electric powered sail plane with some walmart led glow sticks (can find them in the auto section for accents on a car and i just modded them for the plane) and i had no trouble, the sailplane is just so gentle and slow that the lights were easy to keep up with, i dont think i am ready for ic engine powered night flight yet but i can see it is not far away after several successful flights tonight! btw i used 2 different colors on the wings so i know that red is on the right for me and i dont get disoriented!
