Default RE: Rotor Blade Tip Shape

Hi Colin, I have never experimented with tip shape, but it must be important, as I see some full-scale rotorcraft with swept or curved tips these days. Back in the 1980's, I built ultralight airplanes. Some advanced models, such as the Rotec Rally Sport, as well as the famous reflex wing Kasperwings, had wing tip plates. Kasperwings even had multi-hinged tip plates, allowing it to make controlled vertical descents. Many full-scale birds use tip plates or droop tips. Seems there is room for experimentation. Perhaps some model helicopter manufacturer has already conducted such experiments. I'll have to look in some back issues to see what has been done. Happy Flying !!! Charlie Anderson
