Picture
rudder control rod crosses the elevator rod at the auxiliary bulkhead. Adjust the length of each control rod and then
insert into the control surface horn by the “Z“ bend. Check the function, throw (displacement) and the correct sense of
deflection. Then, using the CA glue, attach the guide tubes to the fuselage bulkheads and sides. Now tighten the
screws on the servo arms.
Assembling the fuselage and wings: Glue the lower wing to the fuselage.
Fig.23
Make templates of polystyrene or
balsa as per attached
Fig.
Into the upper wing, cut the opening for aileron servo. Push the servo into the opening as
per
Fig. 24
. Drill the holes in the servo arm to take the 1,6mm wire. Make the slits in ailerons and glue into them the
aileron control horns. Install the control rods into the servo arm and using the “Z” end insert into the ailerons. Check
their function, glue the servo in place and tighten the screw holding the servo arm to the servo shaft. Using the
pictures as a guide, prepare wing joiners of spruce strips (3x10 mm), cut to length and sand their tips to a sharp point,
as per
Fig.25
. Using a sharp blade, cut slits in the wing and fuselage.
Fig.26
The
general
placement of these slits is
marked in the printed colour finish of the model. On the bottom wing the distance of slits from the fuselage centreline
is 335mm and 20mm (front/rear strut, respectively) from the leading edge, respectively. On the top wing it is
335/40mm (interplane/cabane struts) from the fuselage centreline and 20/110mm (front/rear strut) from the leading
edge, respectively.
Using templates, insert the struts into the slits and join the top wing with the bottom one as per
Fig. 27
. Check the angle of incidence, ensure the wings are not warped and glue. Then assemble the cabane section,
using struts of spruce strips (3x8 front, 3x5 back), inserted to the fuselage and the top wing slits as per
Figs.28
. Check
again the proper relative position of wing and struts, angles of incidence and remove the eventual warping, and glue
the cabane struts in place.
Engine cowling: Screw the tested motor with the propeller removed (ensure the proper sense of rotation) with
controller connected, into the motor bulkhead. Thread the controller cable into the cockpit and glue the motor
bulkhead to the fuselage as per
Fig. 29
. Connect the receiver, servos and the controller and test the complete
propulsion unit. Then glue the rear bottom of the fuselage in place

Cut and glue the tail skid from wooden strip
3x10mm.

Undercarriage:
Fig. 32
shows how to assemble and glue together the undercarriage. Put together the wheel disks, fit
the tyres and glue together. The sprung axle is made of 2mm steel piano wire. Attach the axle to the fixed crosswise
axle support with the heat-shrink tubing. Glue the undercarriage to the slits in fuselage and bottom wing, with struts
passing through the glassfibre reinforcing doublers as per
Figs. 33,34,35
.
Battery installation: Install the battery with regard to the centre of gravity of the model. The proven method is to cut a
tightly-fitting opening in the spine and in the front bottom fuselage fairing as per
Fig
.36,37
Test flying: Check the functioning of the RC set and the proper sense of control surfaces’ deflection. Use this initial
setup of the displacement: Ai/- 10 mm, el/-20 mm, /-40 mm.
Check the position of the model’s centre of gravity (CG). It should be 15 mm (+/-5mm) in front of the bottom wing’s
leading edge. We recommend to set the exponentials on the elevator and rudder to 40 %. For the less experienced
pilots (not fully confident they can handle a rudder-equipped machine) it is better to mix the rudder (about 30 %) with
ailerons. You can take-off by a hand-launch or rolling on the ground. The ground take off is more demanding on the
rudder work – keeping the direction during the roll. According to the actual wing loading the model manages wind
velocities of up to 5 m/s.
Many a fine flying experience or a spirited dogfight wishes Free Air
