LANDING GEAR
The landing gear is made from 1/8" music wire with scrap
1/8" balsa fairings. The undercarriage is mounted to the
LG1 and LG2 ply plates fuselage with saddle clamps. Cut
the wire according to the layout on the plan. Bind the axle
to the uprights with copper or brass wire and solder.
DUMMY MOTOR
A dummy rotary engine is provided in the kit. This impor-
tant piece of the model is used to mount (and hide) the AXI
outrunner that powers the plane.
The design is similar to others used in AerodromeRC
models. It consists of a number of laser cut balsa and
ply rings glued together to form the crankcase. The AXI
outrunner bolts to the front ply rings and the whole
assembly gets bolted the model's firewall.
The dummy cylinders are constructed of a couple of laser
cut balsa disks with some card stock wrapped around
them. Cooling fins are simulated by heavy thread that is
glued on.
The fabrication of the engine starts with laminating the
two front 1/16" ply pieces together. A 1/8" lite ply piece
then gets glued to the inside face of the front ply lamina-
tion. The mounting holes for the AXI outrunner need to
be drilled out to 3 mm diameter (about 0.120") so this was
done at this time.
The AXI outrunner sometimes has a large "C" clip on the
front face that holds the sha� in place. The center hole in
the ply mounting plate may need to be enlarged to clear
this, in order for the motor to lay flush against the mount.
Verify the AXI outrunner mounts against the mounting
plate without interference.
The crankcase stack consists of two sections: the front of 3

pieces of 1/4" balsa, and the rear of 7 pieces of 1/4" balsa.
Use a couple of pieces of 5/32" brass tube in two of the
three mounting bolt holes as guides to line pieces prop-
erly. The two sections are joined together using a piece of
laser cut 1/8" balsa as a separator. This 1/8" balsa piece has
notches in it to serve as locator pins for the dummy cylin-
ders.
Each dummy cylinder is built on a piece of laser cut 1/8"
square stock to serve as an indexing pin and to reinforce
the glue joint to the crankcase. Wrap the cylinders with
card stock printed from the decal file. Use the double
thread method to a�ach thin "cooling fins" to the cylinders.
This method uses twin wraps of thread wound around the
cylinder and CA glued only at the top and bo�om. A�er
the thread is set, carefully remove one thread and then CA
glue the remaining thread in place.
Once the balsa sections are glued together the front ply
piece is glued in place and the crankcase is sanded smooth.
Assemble and paint.
Tip: Use aluminium paint followed buy a light coat of
thinned black to simulate an oily finish.
