of the hatch and install the hatch lock

.
41.
Glow Engine:
Apply a coat of fuel-proof dope or epoxy (thinned with
epoxy paint/dope thinner) to the entire fuel tank compartment from the
firewall to the former
38
and the bottom side of the hatch
55
. Apply
a fuel-proofing coat to the front side of the firewall as well; apply the
dope/epoxy over the edges of the covering film to prevent fuel or ex-
haust fumes getting “under the skin”.
42. Epoxy the control surface hinges; be sure the glue does not get into the
hinges hindering the control surface movement. Remove any excessive
epoxy with a paper towel wetted with rubbing alcohol immediately.
43. Cut the covering film over the notches for the fin and horizontal stabi-
lizer in the fuselage; epoxy the fin and stabilizer in place. Remove any
excessive epoxy with a paper towel wetted with rubbing alcohol imme-
diately. Double check the fin was square to the horizontal stabilizer.
44. Epoxy the tail skid in place.
45. Glue the wing bolt captive nuts into the fuselage braces
48
&

.
46. Assemble the main undercarriage and secure it with two M4x20 mm
bolts to the fuselage.
47.
Glow Engine:
Install the engine mount and your engine with silencer.
Insert and glue the throttle push rod outer tube into the fuselage. Install
the throttle servo into the servo tray/switch holder
70
and glue the tray
into the fuselage ensuring free movement of the throttle push rod. You
can fit the receiver battery switch to the tray
70
(flipped by a piece of
0.8 mm piano wire from the outside of fuselage - not supplied in the
kit). Assemble the fuel tank and test it is tight and secure. Install the fuel
tank wrapped in thin rubber foam into the fuselage. Hook up all the tu-
bings - use a pressurized fuel system; do not forget a good fuel filter - like
KAVAN KAV0019 - between the tank and carburettor.
48.
Electric Motor:
Install your motor with the radial mount, thread the
motor cables into the fuselage, connect the ESC (secure it with a strip of
hook and loop tape into the fuselage).
49. Install your receiver, servos and receiver resp. flight battery. Turn your
radio on and set neutral positions of servos. Insert the Z-bend on one
end of the rudder, elevator and throttle push rod into the corresponding
servo arms, thread the push rods into the respective outer tubes, attach
the arms to the servos and secure them with screws. Slide and cyano
plastic tubings on the aileron push rods as a means of stiffening; insert
the Z-bends into aileron servo arms.
50. Secure the control surfaces using strips of masking tape or other suitable
means in the neutral (centre) position. Tack fit the control horns with a
piece of thin double sided sticky tape to the respective control surfaces
so the holes for pushrod in the horns were in line with the hinge pins.
Mark the correct length of the push rods and make Z-bends on them.
Thread the horns on the Z-bends and secure the horns to the control sur-
faces with screws. Alternatively you can install push rod connectors (e.g.
KAVAN KAV3060A/10 - not supplied in the kit) to the servo arms that will
allow precise setting of the control linkage any time.
51.
Glow Engine:
Install the throttle push rod ensuring free movement
over the entire range of the carburettor from fully closed to fully open
position. We recommend fitting a push rod connector to the throttle
servo arm - it will make setting up much easier.
RC SET INSTALLATION AND PREFLIGHT CHECK
Referring to the instruction manual of your radio carefully hook up the
on-board electronics. Once everything has been correctly connected, turn
on your transmitter and plug in the flight (receiver) pack. Check the neutral
positions and throws of all control surfaces. If you needed to make the cont-
rol surface throws smaller, simply move the pushrod closer to the centre on
the servo arm or move it far from the control surface on the control horn.
And vice versa.

The „Low Rate“ recommended control surface throws are suitable for a less
skilled pilot and classic pattern aerobatics; the „High Rate“ setting is for 3D
aerobatics and skilled pilots.
Electric:
Check the direction of rotation of the propeller. If it was incorrect,
simply swap two of the tree wires between the ESC and motor or program
the ESC (refer to the ESC manual).
Glow Engine:
If you install a brand new engine, you will have to run-in
the engine following its instruction manual first. Before take off check the
throttle servo function; double check the idle and full throttle positions are
correct. Be sure you can you can stop the engine by pulling the throttle stick
and throttle trim all the way down or using the Throttle Cut function on
your radio.
Check the correct position of the centre of gravity (CG) – marked “
” on
the building plan. Adjust the CG position by moving the flight resp. receiver
pack - if you could not reach the recommended position, do not hesitate to
add appropriate amount of lead to the nose or tail. An extra couple of grams
won‘t spoil the flying characteristics - but the incorrect CG position is a killer.
Fully charge your flight pack and transmitter batteries, check the proper
function of your radio and perform the range check of your radio according
to its instruction manual. The range has to be almost the same with the mo-
tor off and at full throttle (no more than 10% decrease is acceptable). DO
NOT try to fly unless the range check is 100% successful.
FLYING
The test flying and fine tuning is pretty much straightforward, there will be
no surprise for a medium-advanced pilot that is supposed to fly this model.
