X-Air Flaps
The "F" model or "FLAP" model
is an evolution of the standard X-Air. It has three stage flaps to slow the
aircraft down for landing. The wing and tail on the Flap model also differs
from the standard X-Air. The flap model flies faster than the standard X-Air
because of the different profile wing, and the flap model also costs slightly
more but comes standard with rear wheel pants, doors and wide entry.
