3.
In
order to make sure the
engine
does
not
speed
exces
sively
without a positive control installed,throttle return sprin
gs
must
be left in place.
4. After you have connected the return spring to the throttle servo
you may unhook it (do not remove i
t)
,since
it acts as a spacer
for the butterfly.
The
butterfly
will
work
loose
by re
mo
ving the
return spring.
5.
The
ignition battery should be mounted externall
y,
near the cowl,
at
le
ast
twelve
inches
from
the
receiv
er
or throttle servo that
connects to the receiver.
6.
The
carburetor
needs
at
least
1 1/2"
(38mm)
of
clearance
between the intake and the bottom
of
the
cow
l. If there is less
than 1 1/2", make an
opening
in
the
cowl
below
the
carb
at
least as large as the carb intake diamet
er.
7.A long, narrow,
screw
driver
is recommend to drill small
holes
in the cowl for adjusting the needle valves, since the carburetor
must often be adjusted differently with the cowl on as compared
to off.
8.Th
ese
engi
nes
burn
between
one
and
two
ounces
of
fuel
per
minute. Therefore, a 32 ounce
or
larger tank is r
ec
om
mended.
The engines are equipped
wit
h a
diap
hragm pump c
arburetor
making tank location
not
critical relative to the
carb
uretors fuel
entry position. Place the tank on the aircraft's center
of
gravity
(
CG).
Then
air

trim
changes
during

will
not
be
necessary from a full to an empty tank.
Fuel:
Clean petrol 93# is strongly recommend f
or
your
DLA engines.
Lubrication Ratio

Ignition
system
It is imp
ortant
to
understand
how
the
ignition system is to be
wired. Mount the ignition module using the f
our
supplied
rubb
er
grommets so as
to
create a 1/16" gap between the ignition module
and
the
mounting
surface.
Without
this 1/16"
gap
the ignition
module can overheat.
Important:
If the
electronic
ignition overheats it will malfunction
(e.g., backfiring or shutting down).
Ignition
details:
• The red cable
is
positive (+),while the black is negative(-).
• Working voltage: 4.8v-6v.
•
It
is important to achieve the correct coordination
of
the sensor(s)
,1 to the magnets for fitting a new ignition.
The propeller selection and installation
Make sure the prop, spinner and prop bolts before each flight!
Loose prop bolts allow prop movement which will shear the bolts.
Selection:
• The following props are recommended: 22cm*8cm, 22cm*10cm
• Only use propeller sizes that are recommed above for your engine.
• The propeller blades must be
of
the same length.
Installation:
•
You
must use a drill press to drill your propeller from the rear.
• A drill guide is recommended, but the propeller
washer
can be
used as a drill
template.
(Fix
the
propeller
washer
onto
the
propeller
in
the center-bore using a bolt and nut.)
• keep your propeller balanced.
Engine starting procedu
re
1.
Fill the tank with fresh filtered fuel.
1
2.
Insure that your receiver and ignition batteries are charged, your

to
low.
3.
Close the choke and turn on the ignition switch.
4.
Rubber stick is recommend to start the engine.
5. Begin flipping the prop through its compression stroke until the
engine fires.
6.
Wait for the propeller to stop spinning, turn off the ignition, and
open
the
choke(s).
