In my early aeromodelling days before ‘citizens’ band ‘ radio pinched the 27mHz band and rendered my R/C gear useless , my effective true ‘visual line of sight ‘, was probably significantly less than 100 yds.
It was often impossible visually to determine the orientation of my model or tell whether it was coming or going , despite the application of wide fluorescent orange strips to the wing leading edge of my models.........
