Composite-ARF Extra 330L (2 x 2m)

is not made for crashing, but the landing gear will take
some hard landings without problems. Do not change or
modify it, as the results would only be negative. We had
plenty of time and experience to engineer the strength
needed in this area - and we did !
The Stabilisers:
The stabiliser parts are also vacuum bagged sandwich.
The elevator control surfaces are elastic-hinged, and the
rudder is hinged with a 2mm Ø steel wire, fitted through
phenolic hinge bearing plates, allowing perfect alignment.
The rudder & elevator design gives at least 45 degrees
throw. The horizontal stabs are mounted on a 14mm car-
bon tube and one 6mm Ø glassfibre anti-rotation pin each,
and controlled by one powerful servo installed in the fuse-
lage for each elevator. Please remember during assembly
of the plane to save every gram of weight in the tail area.
The rudder is adequately powered by a single JR8411
servo in the fuselage with a closed-loop system.
Take Care:
Composite sandwich parts are extremely strong, but fragile
at the same time. Always keep in mind that these contest
airplanes are designed for minimum weight and maximum
strength in flight. Please take care of it, especially during
transport, to make sure that none of the critical parts and
linkages are damaged. Always handle your airplane with
great care, especially on the ground and during transport,
so you will have many hours of pleasure with it.
