Greetings and congratulations on your purchase of the version 2 of the Extreme Flight RC
Extra 300EXP ARF
.
Loosely based on our favorite variant of the Extra, the mid-wing
Extra 300, we have taken numerous liberties with this design to produce an aircraft that is
both unique in appearance and flight ability. The designation 300EXP does not belong to
a full scale Extra, but stands for Experimental Progressive. This name was chosen due to
the fact that from its inception the Extra 300EXP was developed as a test bed for several
new forward thinking design and aerodynamic concepts. This new V2 version further
refines the original concept with additional use of composites resulting in a stiffer,
stronger airframe and a slight reduction in weight.
The Extra 300EXP incorporates carbon fiber and G10 composites into the structure of the
airframe, resulting in a lightweight, yet twist free structure capable of handling extreme
aerodynamic loads. Carbon and G10 are used in high stress areas such as motor box
support, landing gear mounting structure and fuselage longerons to provide enormous
strength and durability. A true piece of carbon fiber art, the landing gear is airfoiled and
has just enough "give" to cushion those not so perfect landings. The removable wing
panels are mounted on a carbon fiber wing tube and are fastened to the fuselage with
nylon thumbscrews. The large canopy (which is retained by a spring loaded hatch latch)
has been moved forward to place the tallest portion of the aircraft at the center of gravity,
resulting in the best knife edge performance of any aircraft we've flown to date. All
control surfaces are pushrod driven with short linkages and use ball links for slop free
actuation with no binding. Optional Side Force Generators are included and add to the
already generous side area, increasing yaw axis authority and adding stability in all angles
of sideslip. Expertly painted fiberglass cowl and wheel pants and 2 gorgeous high
visibility Ultracote color schemes add the finishing touches and make this an airplane that
you will be proud to show up at the flying field with. The combination of these unique
elements add up to an aircraft that pushes the boundaries of modern aerobatic flight.
If repairs become necessary, the Ultracote colors used on the Extra 300EXP are as
follows:
Yellow/Red/Blue/Silver color scheme: Cub Yellow. Midnight Blue, Silver, True Red
Orange/White/Blue color scheme: Orange, White, Midnight Blue, Sky Blue, Silver
Extreme Flight R/C reserves the right to alter the assembly process at any time. While we
do our best to update the manuals, sometimes there are minor changes in the process of
the build. If you have any questions regarding assembly please contact us before moving
forward.
