Wondering if anyone has found any lighting that can be attached to the P3 for better visual tracking? My commercial exemption will probably limit me to 500 ft. AGL and line of sight and being able to see the craft at distance would be a great help. Don't want to even think about affecting the aerodynamics of the craft so whatever I might consider would have to be light, bright and not causing any flight issues. Anyone tried this or have suggestions? How about the strobes that bicycle riders use? Too heavy?
