High flight time RC aircraft
Building a high flight time RC aircraft, which is easy to carry and fly, made out of easily available materials (foam), and reusing my existing electronics After deliberations, decided on a simple dihedral (rudder and elevator) tractor of 40" span.. Wing chord was kept at 7" (below that airflow disruption due to low Re number) It would be flying at low Reynolds numbers (around 80000),accordingly a thin and slightly under-cambered (4 degree) plate airfoil section was chosen. The dimensions / parameters were calculated based on the design requirements and based on RC aircraft parameters. This aircraft regularly flies + 45 minutes flights on a 1000 mah bty..and is super easy to fly . Many a times after reaching a good altitude & trimming the aircraft I have taken a short break. She can hold bearing even in windy conditions. Just by pointing her into a decent wind and with very minimal ground speed (zero or sometimes negative)she can gain altitude. DIMEN...
