RC MODEL - FAUN Welcome and congratulations on your purchase

Welcome and congratulations on your purchase. We hope that our product will
provide you with many enjoyable flying hours as well as be a pleasure to build.
Please treat this manual as a guide only. Your own modifications to the building
process are welcome.
We believe that the following steps are essential in achieving a success with the
Before commencing with the assembly read the entire manual.
Trial fit all parts.
All glued parts (and their mating components) should be sanded using ≈240
sandpaper. This applies mainly to all plywood reinforcements in fuselage, tow
hook and inner nose cone.
Accurately and neatly finished models usually fly better.

Cut out the ailerons with a sharp hobby knife. With a blunt tool (a piece of hardwood)
push in the foam on aileron and wing sides to a depth of 2-3 mm. Fill the voids with a
mixture of 5min epoxy and microballoons. Allow the epoxy to cure completely. Sand
the sides flush. Sand the bottom edge of the aileron so that it can deflect down.
Assemble the wing halves together and mark the position of the hardwood blocks on
the skin, as per the general arrangement drawing. Remove the foam in each wing to
the depth of half width of the hardwood blocks. Shape the blocks to achieve a loose
fit. Using a blunt tool push in the foam to a depth of approximately 1mm around the
perimeter of the wing root. This operation will allow a stronger wing joint.
The position of the wing servos is marked on the wings. Cut out the veneer and
foam so that a servo fits very snugly inside the servo hole. Route the aileron
extension cables inside the wings. Music wire can be used to pull the wire through.
Lay down a piece of wax paper to protect your building board. Smear 1hour epoxy
inside the holes and the entire wing root area. Insert the hardwood blocks and make
sure that the space between the hardwood blocks and the top and bottom veneer is
filled up with the epoxy. While holding one wing half flat on the building board, apply
50mm dihedral at the tip of the other wing half. The wings have been already sanded
to the correct dihedral. Make sure that both wing halves match each other. Masking
tape can be used to hold the wing halves together. Allow the epoxy to cure
Apply the provided strips of fibreglass cloth at the top and bottom of the dihedral
break. Use slow curing epoxy (1 hour) in order to achieve a good penetration and
Drill two φ4mm holes through the hardwood blocks for the wing bolts. The holes
should be perpendicular to the top surface of the wing, see the general arrangement
At this stage the wing should be sanded lightly with a fine sandpaper and sealed with
a clear varnish. Any type of a suitable, lightweight varnish can be used to protect the
wing and tail from moisture and aging. Although an epoxy was used to glue the
veneer to the wing cores, care should be taken when using non-water based
varnishes so as not to destroy the wing foam.
Ailerons can be attached with a clear tape. Start at the top surface and then turn the
aileron flat on the top of the wing. Tape the bottom surface.
Install the aileron horn directly in line with the servo arm.
The edges of the tail have been already pre- sanded to a correct angle. Join all three
parts together using a 5min epoxy. We recommend using cardboard templates to
hold the V-tail while the glue cures. Reinforce the joints with pieces of the supplied
fibreglass cloth.
The tail can be permanently glued to the fuselage or alternatively attached using M3
bolts. The former method is quick and easy but can be problematic during transport.
Details of the bolted version are provided in the following section “Fuselage”
Wing position on top of the fuselage:
- S6063 profile: move the wing forward by approximately the thickness of the
leading edge.
Cut a hole in the wing seating so that a receiver can be inserted. Glue the wing
seating plates using 5min epoxy. The wing seating plates can be shaped to a slight
V angle to accommodate the wing dihedral.
Using the wing holes as guides, drill two φ4mm holes in the fuselage (and wing
seating plates). Double sided tape can be used to hold the wing during this
operation. Take off the wing and rebore the fuselage holes to φ5.5mm and insert the
provided nuts. Place the wing on top of the fuselage again and trial fit the wing bolts.
It is important for the nuts to fit tightly inside the fuselage holes up to the collar. Lock
the nuts in place using CA glue.
Should you have opted for a removable tail, glue the plywood reinforcement to the
tail seat (inside the fuselage). Drill 2 φ3mm holes in the V-tail mount. Place the tail
on top of the fuselage and drill φ3mm holes using the tail holes as guides. Make sure
that the tail is correctly aligned. Lock the brass nuts in place using CA glue. Install
the supplied control horns.
If required, install a tow hook using 2-3 layers of fibreglass as reinforcement.
Bowden cables can be glued at 2-3 places inside the fuselage using CA or epoxy
glues. Alternatively, they can be glued to a 3mm piece of balsa shaped to conform to
the inside contour of the fuselage. The entire assembly is then glued inside the
Cut a hole for the receiver battery in the inner nose part. Insert through this hole a
φ26mm plate cut from the supplied plywood. This plate will act as a closure for the
ballast compartment. Drill a hole on top of the ballast compartment so that small
pieces of lead can be inserted.
Cut holes for the servos. It is recommended to reinforce with plywood the areas
where the servos will be bolted down. Drill holes for the bowden cables.
Drill 4 φ4mm holes around the circumference of the inner nose cone, 7 mm from the
edge. These holes will allow excess glue to drain away as well as provide a better
bond. Insert the inner nose cone deeply into the sheath nose. Trial fit it into the
fuselage. Light sanding may sometimes be required in order to obtain a good fit
inside the fuselage. Sand the outside of the inner nose cone and the inside of the
fuselage (the areas to be glued together) with a fine sandpaper. Smear the inside of
the fuselage with 5min epoxy and push in the sheath nose/inner nose assembly into
the fuselage. Carefully align the sheath nose with the fuselage and tape the joint
line. Use a liberal amount of epoxy for this operation but be careful not to glue the
sheath nose to the inner cone.
This model can be flown with a rudder/elevator/aileron or just elevator/aileron.
Micro servos should be used in the fuselage. Wing servos can be installed using a
small amount of silicon sealer. Before gluing the servos into the wings, wrap them
around with an electrical insulating tape.
Insert 270-350mAh battery into the fuselage.
The receiver is positioned behind the servos and the aerial can be routed inside the
Recommended Control Throws:
Elevator – 9mm up/down
Aileron – 9 up, 5 down
Rudder – 9 left/right
These are only recommended initial throws and can be changed to suit individual
flying styles.
For the first flights we recommend that the model should be balanced 70mm from the
leading edge, measuring in the CL of the fuselage. After the first flight the CG
position and wing incidence angle can be adjusted to suit individual flying styles.
However, any suitable motor and reduction gear can be used. Cut the nose of the
electric fuselage at the diameter of the spinner. The fuselage CL is already set ≈2°
down, so no extra down thrust angle is required, see Figure 1. Just set the motor
mount parallel to the nose closing bulkhead. The motor mount can be made from a
plywood-epoxy board laminate, each approximately 1.6 mm thick. Cut the air vent
holes and drill holes for the motor fixing screws. Glue the motor mount using epoxy
and carbon fibre tows. Trim the inner nose cone to suit the motor/reduction gear
