Organic 2.5 SP
The Organic is a 2 metre Glider designed specifically for the American 2
metre Class.
Available in 2.0 M SP or 2.5 SP Meter versions the model is ideal for 2
meter thermal soaring competitions, F3J or Sport Thermal Soaring. The
model is also ideally suited to Slope flying.
The Three-piece wings are a unique construction of high-tech materials and are
the feature that sets this model apart from the rest. Using free flight
technology and combining the best high tech materials to produce a model of
outstanding strength combined with lightweight.
The wing "D" box is of Kevlar cloth, fitted over balsa ribs and riblets and
bonded to a carbon spar. Each Rib is capped with a solid carbon cap strip. A
solid carbon trailing edge completes the wing. The ailerons and flaps are
knuckle jointed with shrouded gaps. Carbon joiners retain the wing tips. The
wing panels are covered in Oracover.
The use of combined high tech materials produces a wing of outstanding
strength and torsional rigidity that is still extremely light in weight. To be
appreciated the construction of the model has to be seen. The wings are
extremely strong and are capable of being winch launched or two man towed
without problem. The flapped MH32 wing section ensures that the model has
an extremely wide speed range and good thermal flight characteristics when
flown from either the flat or the slope.

Building Instructions
Please read all building instructions first before proceeding.
These instructions are for the general guidance of the builder only; please feel
free to complete the model using your own favourite methods of assembly or
equipment.
The model is delivered ready covered, care should be taken to protect the
surface finish during the installation of the radio control equipment and control
linkages.
Note: - Further items will need to be purchased in order to complete
this model.
Receiver, battery, 5 – servos and Hoopes wiring harness
Glider /electric Version: -
1.) Wings: -
Feed the Aileron servo wires into the ready cut slots in the wings and fit a
reliable plug and socket system to the wires to enable the panels to plug
together and the wing servo's to plug into to the fuselage mounted receiver.
We recommend using the Hoops Wiring Harness. These will fit directly into the
pre- cut slots in the root ribs.
Prior to mounting the aileron servo's into the wing servo wells, clean any
release agent from the Carbon Sheeting inside the servo well using acetone,
and abrade the surface to ensure a good bond to the servo or mounting rails.
The servo's can be secured using hardwood blocks bonded into the wells, the
servo's being retained with wire straps screwed into the blocks. Alternatively
the servos can be simply bonded in place using 5 minute epoxy, score or
abrade the surface of the servo to ensure a good bond. The latter is my own
preferred mounting method.
2.) Bond the aileron horns of choice to the ailerons, aligning the horn up with
the servo output arm. The flap servo is mounted in a similar way to the aileron
servos. Ensure the flap movement will give approximately 70 degrees of down
movement
3.) Vee Tail:
Fit the Vee tail plane to the fuselage, hold the elevator horns in place and
mark out the correct position of the horns so as the horn correctly align with
the pushrods in the fuselage.
Check that the horn fits in the fuselage neatly and the tail plane will move up
and down to its full extent of travel without hindrance. Securing the elevator
horns to the elevators using epoxy or Cyo. (Ensure full elevator movement is
possible)
4.) Fuselage:
The Fuselage is delivered with a separate nose cone and inner fuselage
nose section.
Fit the completed wings and tail plane to the fuselage and tape the rudder and
elevator servos, the receiver and the receiver battery to the outside of the
fuselage. Connect the servos to the Vee tail horns using a the etched Teflon
housing and 0.40 dia. carbon pushrods.
The Tow hook should be positioned approximately 6 to 10 mm in front of the
CG. (Adjust to suit personal taste)
Organic 2 M SP & 2.5 SP
The completed 2 M model should balance at a point about 80-87 mm from the
leading edge of the wing and the 2.5 SP 95-102 mm.
Add lead to the nose of the model to achieve this. The centre of gravity can
only be correctly positioned when the model is flown, as the ultimate position is
one of personal choice. Once the correct CG position is determined, bond the
lead into the nose of the model.
It is better to carry extra battery power than lead nose weight.
Note: - The R/C equipment is mounted on the underside of the inner fuselage;
Nicad and receiver must be secured in place with waterproof tape to ensure
that they remain in their correct place when the sheath nose is removed.
Mark the position of the receiver, battery and servos on the inner nose. Cut out
rectangular slots for each component. Fit the servos by screwing down onto
plywood or epoxy board strips placed on the under surface of the inner nose.
The positions of the servos and the Receiver in the inner nose can be reversed
from that shown in the sketch below if desired.
Strengthen the fuselage around the area of the tow hook mounting plate using
multi layers of glass cloth and Epoxy resin, Bond in place a 3 mm thick epoxy
board plate to spread the launching load across the fuselage. Strengthen with
glass cloth.
Flying the model can only accurately set the tow hook and CG positions; they
are also a matter of personal taste.
5.) Electric Flight version: -
An electric flight fuselage is available as an optional extra.
Prepare a motor mounting ring from plywood at least 5 mm thick, or a laminate
of 1.5 mm epoxy board and 3 mm plywood. Bond the motor mounting ring into
the fuselage with epoxy resin and micro fibre or chopped strands and carbon
fibre tows.
The batteries will fit behind the motor and into the space under the wing
mounting. The elevator and rudder servos should be fitted to the rear of the
space under the wing mounting.
The layout of electric flight equipment within the fuselage is dependant on the
size and weight of the equipment used, and should be placed to achieve the CG
position.
The recommended layout of the electric flight equipment is as follows: - From
nose to tail: - motor, speed controller, battery, servos and receiver. If a
separate receiver battery is used, this should be positioned to suit the CG.
6.) Recommended Control Movements: -
Elevator + 12 mm / - 8 mm
Rudder + 12 mm / - 12 mm
Ailerons + 16 mm / - 10 mm
Launch setting: - Flaps: - 12 mm down - depending on wind strength
Ailerons:-6mmdown
Elevator: - + 1 mm, Mix in up elevator on successive
launches, until model starts to weave on the line, then
reduce setting slightly to give a straight launch
Butterfly Flap: - - 70 deg down
Aileron:-+15mmup
Elevator - 2 mm - Set to suit, the model should not
balloon up when the brakes are applied
Speed: - Flaps and Ailerons: - Reflex Up + 1 mm to + 3 mm,
Elevator -1 to -1.5 mm down, adjust to suit.
Distance: - Flaps and Ailerons: - Neutral, Elevator - Neutral.
Thermal: - Flaps and Aileron: - Down - 3 mm to 5 mm,
Elevator + 1 to 1.5 mm up, Adjust to suit.
Flap. Aileron - Elevator Mixing: -
Speed: The Rudder coupling is switched off
Up elevator is coupled to Down Flap - Full up = + 5 mm
flap (down)
Distance: Up elevator is coupled to Down Flap - Full up = + 5
mm flap (down)
Thermal: Up elevator is coupled to Down Flap - Full up = + 5
mm flap (down)
Rudder / Aileron Mixing.
Coupled Rudder with aileron can be used for all tasks
except Speed Flying; For Speed the coupling should be
switched out, preferably as part of the programme in
the transmitter.
These instructions are for general guidance only, please feeling free to
complete the model in your own favourite methods. Please fly your ORGANIC in
safe manner. Please remember, it is always better to check before you launch
than rebuild after you crash.
We welcome any Recommendations or Alterations, Settings or Tips in
order to improve these instructions.
