CONSTRUCTION GUIDE
1 Epoxy the 2 identical plywood wing joiners together.
Cut out aileron servo opening on top of wing panels.
2 Looking forward towards the leading edge, the wing should form a "V" when assembled.
The top of the wing has lettering on it.
3
4Install the main landing gears as shown. Attach with the screws that you should have purchased
(No. 2 by 1/2")
Next, glue the hardwood torque rod covers in place. They have a notch in them to allow for
movement of the aileron rod. You may have to enlarge the holea little to allow for proper
movement.
The wing is joined together by inserting one plywood dihedral braces into each wing panel and
then epoxying into place.You may want to check the fit first, before gluing. Make sure that the
wing panels butt together closely so that the dihedral angle is correct. Before gluing, you can
cut into the wing panels a hole large enough to accommodate the plywood servo mount.This mount is
2*3/8" by 1*9/16" and fits onto the dihedral brace, it is supported by two pieces of plywood
1*1/16" by 1*1/16" one which should be glued to the dihedral brace after the wing is joined
together.(It protrudes through the top on the low wing versions.) Apply a liberal amount of epoxy
to the brace and to the wing panels when joining together, wipe off any excess, and then tape the
panels together to insure a good glue joint. Once together, glue in the servo mount. A piece of
clear plastic tape is wraped around the center section of the wing to seal the glue joint.

6Assembly the fuel tank as shown. Apply a bead of silicone sealant around the fuel tank cap as
shown when installing it into the fuselage.
Hook up noes wheel steering pushrod and route through housing which is installed into servo area.
The nose gear is incorporated into the engine mount. The steering cable is routed along the left
side of the fuselage and attached to rudder servo.Check the diagram for assembly.
7Offset the engine by two degrees to the right. Drill four 7/64" holes for the engine. Use the
selftapping screws supplied. Install the nose wheel assembly at this time.
8The elevator must be attached to horizontal stabilizer using 3 hinges. You may have to trim the
elevator to fit the stabilizer. The stabilizer should be flush with rear of the fuselage as per
the diagram.
IT IS ESSENTIAL THAT THE STABILIZER AND THE RUDDER ARE 90 DEGREES TO EACH OTHER, AND THAT THE
WING 15 PARALLEL TO THE STABILIZER.
A good way to check the alignment is to first attach the wing to the fuselage. Slide the
stabilizer into the fuselage, making sure that it is centered. Place the airplane on a table or
some steady surface and then stand back. Look at the airplane from the front, the engine would be
the closest thing to you. Stand back about 8 feet and try to have your sight level with the
engine. It will be immediately apparent if the wing is not parallel with the stabilizer.
Trim the fuselage to fit the stabilizer properly. Fill any gap with scrap wood or epoxy.
Glue vertical stabilizer into the fuselage and onto the stabilizer. The rudder attaches to the
vertical stabilizer with two hinges.
9
The wing is mounted to the fuselage by using (80)#64 rubber bands.
The bands are designed to pop off during hard langings and thus help prevent major
damage.Four rubber bands are needed per side.
Two wooden dowels are inserted through the fuselage to hold the wing in place. No.62
rubber bands are used to attach the wing.At least 4 rubber bands should be used on each
side.
Wrap the bands around the wooden dowels as shown above.This design is to allow for those
not-so-perfect landings that come with learning how to fly.
At this time be certain that the aileton servo is connected to the receiver,otherwise the
wing will need to be removed later to connect it.
10
The pushrods are made of wood and are to be assembled as shown in the drawing.
Attach the rod to the servos with a anap keeper, the same as the aileron pushrods. The
throttle pushrod is just a length of 3/64" wire sliding in the preinstalled tube. Be sure
to adjust it so that you have full movement of the carburetor without stalling the servo.
Check the size of the servo holes in the fuselage servo tray; alter as necessary. epoxy
into the fuse, and install the servos. Tutn on the system and check the operation of the
servos; they shuold all work without interfering with each other or the fuse.
Attach the rod to the horn, set the surface and the servo to neutral, and mark the length
on the ftont rod. Remove the rod, make a rightangle bendin the wire, and cut off the
escess.
The bent rods included are for the servo ends and the threaded todsare for the back ends.
After mounting the control horns on the rudder and elevator (use the squares of clear
plastic between the horn and the surface, and between the nut plate and the surface) you
11 The canopy is installed as shown using epoxy glue.
12 The amount of the travel needed for the variour control surfaces is shown.
