The spin is a favourite rc airplane aerobatic maneuver and spins can go very well or disastrously wrong, depending on how much altitude you leave yourself to recover! During a spin, the airplane flies vertically downwards while rotating about it’s longitudinal axis (i.e. about its fuselage). To be technically correct, a spin should be performed with neutral ailerons and by applying full rudder only, but realistically many rc planes spin better when full aileron and full rudder is applied*.
How to fly it: Enter the maneuver in to wind, flying straight and level but at a slow speed and with plenty of altitude (point ‘A’ in the picture above). Slow your airplane further by reducing throttle completely and applying up elevator – not too much, but just enough to initiate a stall. Use ailerons to keep the wings level at this point.
The timing here is quite critical, you need to apply full rudder (*and full aileron, both in the same direction) just as the airplane stalls, point ‘B’ in the picture.
If you’ve got it right, the airplane will continue its stall while entering a spin. Keep both rudder and aileron fully deflected for as long as you want to hold the spin. Recovery is simply a case of returning rudder and aileron to neutral while applying up elevator and throttle to pull the airplane out of the dive (point ‘C’). Ideally you should recover from the spin with the plane flying in to wind.
