Remove the cowl and the sliding motor
mount box. Mount your motor onto the
box using the M3x20 socket head
machine screws and M3 blind nuts provided. Carefully measure back 3 3/4" from
the rear of the propeller and put a mark on the side of the box. Slip the box into the
fuselage but DO NOT GLUE IT IN YET.
Install the cowl and verify that the prop clears the cowl by about 1/2 inch and that the
prop shaft is near the center of the opening in the dummy engine. If you chose to
use a different motor and it is shorter than the Maxford U35425 that we used in the
prototypes, you can slide the motor box forward to make prop shaft come out nearer
the center of the hole. When you are happy with the fit go ahead and glue the box
into the fuselage.
The best place for the ESC is inside the small box that protrudes from the firewall
below the motor, but you can also mount it above or along side of the motor mount.
INSTALL THE STABILIZER:
Locate the three wooden control
horns. Slide these into place through
the pre-cut slots in the elevators and
the rudder. Glue them in with thin
CA.
Attach the stabilizer to the top of the
fuselage using the M3x16 machine
screws provided. The short pre-
covered plywood bar that looks like a
front cabane strut is used to reinforce
this joint. Put the screws through the
bar first, then through the stab, then
into the blind nuts in the fuselage.
Use a threadlocking compound on these screws.
