while facing into the wind. Secure the
Sportsman S+ and give it full throttle for
a few seconds. The first time the aircraft
reaches full throttle, it locks the GPS
coordinates as the center of the runway.
If you are not at the center of the
runway and initially run full throttle
after powering on, you will inadvertently
assign the wrong runway GPS
coordinates. Keep this in mind during a
preflight check or while taxiing. After
the initial full-throttle run to assign the
runway coordinates, the pilot can run
full throttle again and not accidentally
reassign the runway coordinates.
Takeoffs from the runway were
smooth. As with other SAFE-enabled
aircraft, in beginner mode the Sportsman
S+ practically takes off by itself.
Although the model is capable of grass
takeoffs or hand launches, I opted to fly
from geotextile and concrete runways.
The wheel pants look great, but I feared
the smaller wheels and pants could be a
problem in thick grass.
The aircraft flew extremely well,
as expected with SAFE+ and AS3X
integration. In later flights, I flew in 20
mph winds. Although affected by the
wind, the Sportsman S+ still handled
well, especially in beginner mode. In
expert mode and in calmer conditions, I
conducted some mild aerobatics such as
loops. As with most high-wing trainers,
