MODELS . e RENO AIR CARE YAK-11 “PERESTROIKA” was designed with the inter-
mediate/advanced sport yer in mind. It is a semi scale airplane which is easy to y and quick
to assemble. e airframe is conventionally built using balsa, plywood to make it stronger than
the average ARTF, yet the design allows the aeroplane to be kept light. You will nd that most
of the work has been done for you already. e motor mount has been tted and the hinges
are pre-installed. Flying the RENO AIR CARE YAK-11 “PERESTROIKA” is simply a joy.
is instruction manual is designed to help you build a great ying aeroplane. Please read

STROIKA” Use the parts listing below to indentify all parts.
Please be aware that this aeroplane is not a toy and if assembled or used incorrectly it is ca-
pable of causing injury to people or property. WHEN YOU FLY THIS AEROPLANE YOU
ASSUME ALL RISK & REPONSIBILITY.
If you are inexperienced with basic R/C ight we strongly recommend you contact your R/C
supplier and join your local R/C model Flying Club. R/C Model Flying Clubs oer a variety
of training procedures designed to help the new pilot on his way to successful R/C ight.

HINGING THE AILERON.
Note : e control surfaces, including the ailer-
ons, elevators, and rudder, are prehinged with
hinges installed, but the hinges are not glued in
place. It is imperative that you properly adhere
the hinges in place per the steps that follow us-
ing a high-quality thin C/A glue.
1) Carefully remove the aileron from one
of the wing panels. Note the position of the
hinges.
2) Remove each hinge from the wing panel
and aileron and place a T-pin in the center of
each hinge. Slide each hinge into the wing
panel until the T-pin is snug against the wing
panel. is will help ensure an equal amount
of hinge is on either side of the hinge line
when the aileron is mounted to the aileron.
3) Slide the wing panel on the aileron un-
til there is only a slight gap. e hinge is
now centered on the wing panel and ai-
leron. Remove the T-pins and snug the
aileron against the wing panel. A gap of
1/64” or less should be maintained be-
tween the wing panel and aileron.
NOTE : e hinge is constructed of a spe-
cial material that allows the C/A to wick
or penetrate and distribute throughout
the hinge, securely bonding it to the wood
structure of the wing panel and aileron.
4) Deect the aileron and completely sat-
urate each hinge with thin C/A glue. e
ailerons front surface should lightly con-
tact the wing during this procedure. Ide-
ally, when the hinges are glued in place,
a 1/64” gap or less will be maintained
throughout the lengh of the aileron to the
wing panel hinge line.

5) Turn the wing panel over and deect the
aileron in the opposite direction from the
opposite side. Apply thin C/A glue to each
hinge, making sure that the C/A penetrates
into both the aileron and wing panel.
6) Using C/A remover/debonder and a paper
towel, remove any excess C/A glue that may
have accumulated on the wing or in the
aileron hinge area.
7) Repeat this process with the other wing
panel, securely hinging the aileron in
place.
Install the ap control horn using the
same method as same as the aileron con-
trol horns.
8) Aer both ailerons are securely hinged,
rmly grasp the wing panel and aileron to
make sure the hinges are securely glued
and cannot be pulled out. Do this by care-
fully applying medium pressure, trying to
separate the aileron from the wing panel.
Use caution not to crush the wing struc-
ture.
Work the aileron up and down sev-
eral times to “work in” the hinges
and check for proper movement.

Because the size of servos dier, you
may need to adjust the size of the precut
opening in the mount. e notch in the
sides of the mount allow the servo lead to
pass through.
1) Place the servo between the mounting
blocks and space it from the hatch. Use a
pencil to mark the mounting hole loca-
tions on the blocks.
4) Use dental oss or heatshrink tube to
secure the connection so they cannot be-
come unplugged.

OPTIONAL RETRACTABLE
LANDING GEAR.
Electric retractable landing gear is not
included in this kit, however it is a very
popular add-on as optional. If you want
to use retracts in your RENO AIR CARE
YAK-11 “PERESTROIKA”, we recom-
mend that you buy a good set of electric
retracts as the Himark AM05 Main Gear
shown as below. ese retract units will
bolt right into the RENO AIR CARE
YAK-11 “PERESTROIKA” inplace of
the standard ed gear.

INSTALLING THE FUSELAGE SERVOS.
.
Because the size of servos dier, you
may need to adjust the size of the precut
opening in the mount. e notch in the
sides of the mount allow the servo lead to
pass through.
1) Install the rubber grommets and brass
collets into all servos. Test t the servos
into the fuselage servo mounts.

tubes leaving 1/2” protruding from the
rear of the stopper. is will be the fuel
pick up tube.
2) Using a modeling knife, cut one length
of silicon fuel line. Connect one end of
the line to the weighted fuel pick up and
the other end to the nylon pick up tube.

at a 45º angle. is tube is the vent tube.
4) Test t the stopper assembly into the tank.
It may be necessary to remove some of the
ashing around the tank opening using a
modeling knife. If ashing is present, make
sure none falls into the tank.

FUEL TANK INSTALLATION.
7) Slide the fuel tank into the fuselage. Guide
the lines from the tank through the hole in
the ewall.
6) When satised with the alignment of the
stopper assembly tighten the 3x20mm ma-
chine screw until the rubber stopper expands
and seals the tank opening. Do not overtight-
en the assembly as this could cause the tank
to split.
5) With the stopper assembly in place, the
weighted pick-up should rest away from the
rear of the tank and move freely inside the
tank. e top of the vent tube should rest just
below the top of the tank. It should not touch
the top of the tank.

You should mark which tube is the vent
and which is the fuel pickup when you attach
fuel tubing to the tubes in the stopper. Once
the tank is installed inside the fuselage, it may
be dicult to determine which is which.

ENGINE MOUNT INSTALLATION.
1) Locate the items necessary to install
the engine mount included with your
model.
2) Use four 4x30mm head bolts and four
4mm washers to attach the engine mount
rails to the ewall. Tighten the screws
. Make sure to use threadlock on the
screws to help prevent them from vibrat-
ing loose.

MOUNTING THE ENGINE.
1) Position the engine with the drive
washer (145mm) forward of the ewall as
shown.

2) Use a pin drill and 4mm drill bit to drill
a small indentation in the mount for the
engine mounting screw.
Blow through one of the lines to ensure
the fuel lines have not become kinked inside
the fuel tank compartment. Air should ow
through easily.

3) Use a drill to drill the four holes in the
engine mount rails.
4) e rewall has the location for the
throttle pushrod tube (pre-drill).
5) Slide the pushrod tube in the rewall
and guide it through the fuel tank mount.
Use medium C/A to glue the tube to the
rewall and the fuel tank mount.
6) Connect the Z-bend in the 450mm
throttle pushrod to the outer hole of the
carburetor arm.
7) Slide the throttle pushrod wire into
the tube. Position the engine between the
mounts. Use four M4x30mm machine
screws to secure the engine to the mount
as shown.

er the throttle stick and trim and install
the servo horn perpendiular to the servo
center line.
9) Move the throttle stick to the closed po-
sition and move the carburetor to closed.
Use a 2.5mm hex wrench to tighten the
screw that secures the throttle pushrod
wire. Make sure to use threadlock on the
screw so it does not vibrate loose.

1) Tape the cowl to the fuselage using
low-tack tape.
2) Use a drill and drill bit to drill the holes
for the cowl mounting screws. Make sure
the cowl position is correct before drill-
ing each hole.
3) With the muer, needle valve, and
spark/ glow plug removed from the en-
gine, slide the cowl in place over the en-
gine. Temporarily install the propeller
and spinner in order to d the exact loca-
tion of the cowl. When satised with the
cowl placement, secure the cowl to the
fuselage using masking tape.
4) Install the muer and muer exten-
sion onto the engine and make the cutout
in the cowl for muer clearance. Connect
the fuel and pressure lines to the carbu-
retor, muer and fuel ler valve. Secure
the cowl to fuselage using the M3x10mm
socket head screws. Putting a small length
of silicon fuel tube under the head of the
screw helps with vibration.
