4. The wheel pants may be mounted either as a perma-
nent installation or removable for flight. To mount
them permanently, do the following:
5. Mount the gear leg into the slot in the wing. Slide F27
onto the wire. Slide the wheel onto the wire and posi-
tion the inside half of the wheel pant to the wire.
Mark the position where the wire meets the plastic.
Check for wheel clearance. Bolt the wheel pant to
the gear leg using a gear strap. Epoxy F27 to the
wheel pant. Place the outside half against the inner
half and check for clearance. When satisfied, perma-
nently mount the wheel, and glue the wheel pant
halves together. Paint to match your color scheme.
The down side to permanently mounting the wheel
pants is that access to the wheels is impossible.
Removable wheel pants can be accomplished by adding
blocks to the inside edges of the wheel pants. Drill through
the blocks and screw the wheel pants together. Add the
gear strap to mount one half to the gear leg, and cut F27 in
half and glue to each wheel pant half to locate to the gear
leg. Paint to match your color scheme, and remove for
flight.
6. Locate the cowl to the fuse and mark the screw loca-
tions. Gluing a piece of carbon fiber or aluminum to
the cowl at the screw hole will add strength to this
area and will prevent cracking.
Servo and Receiver installation
3/8” maple blocks are provided for servo rails. Mount
these as shown on the plans and mount the servos.
Mount the receiver and connect the components. The bat-
tery may be mounted in a location that will aid in balanc-
ing the airplane.
Covering
Cover the airplane with the covering of your choice. The
covering choices are too numerous to mention, but the
airplane shown in the photos was covered with film, paint-
ed, and clear-coated. It is recommended that the airplane
and control surfaces be covered separately.
Control Surfaces
Locate the control arm positions, and install the control
arms. Final sand the control surfaces. Locate the hinge
points (hinges and other hardware are not provided int he
kit because everyone has his own preferences. Rather
than put in stuff that most of you will throw away, we left it
out to keep the kit price down) and install the hinges and
control surfaces. Use at least three hinges per control sur-
face for best results. Connect and adjust the pushrods.
Fuel Tank and Throttle Cable
After deciding which direction the engine will point (up,
down, or sideways) drill holes for and install the throttle
cable. Mount the fuel tank of your choice, and connect the
lines.
Center of Gravity:
The CG is measured with the aircraft UPSIDE DOWN 3-
7/16” back for the wing leading edge, where the wing
meets the fuselage.
Control Throws:
Ailerons: 7/16” up & down
Elevator: 7/16” up & 3/8” down
Flaps: 1” down
Rudder: 3/4” left & right
Flying
The Stuka is a very stable flyer, but approach the first few
flights with caution; it will take several flights to “dial in” the
flap and aileron incidences, so as you make changes,
make them gradual and incremental. Large adjustments
may create the opposite effect you were intending!
The rest is up to you! Fly and enjoy!
The remainder of the construction consists of attaching
the rest of the components to the airplane. Most of this is
builder’s choice, and individual tastes, styles, and compo-
nent selection, so any detailed descriptions would be
impossible. The remainder of assembly is described in
general terms only.
Engine installation
Measure and mark the center horizontally and vertically of
the firewall; this will be the centerpoint for motor mount
installation. Install the motor mount and engine of your
choice. The photos of the airplane are shown with a .61
installed inverted, completely enclosed. Inverted engine
installation causes it’s own set of problems, so the flat fire-
wall allows the engine to be installed pointing any direc-
tion that suits you (side mounted with a Pitts-style muffler
will hide most of the engine/muffler and exhaust system).
