6mm machine screws. Grind or file a flat spot at
the point of set screw contact. This provides a
better area for the screw to bite and helps keep the
wheel in place. Trim off any excess axle wire after
installing the outer wheel collars. Cycle the retract
and adjust the position of the axle and wheel to
prevent any binding of the wheel in the well. Mark
the location at which the set screw in the axle
contacts the strut, and grind or file a flat spot at the
point of set screw contact. This provides a better
area for the screw to bite and prevents the axle
from rotating on the strut. Use threadlock on the
screws to prevent loosening.

Tail Wheel Installation

1. Just so you don't forget, the tail wheel must
be installed in order to taxi the aircraft. Slide the tail
wheel onto the tail gear, and use a 2mm wheel
collar and the 3mm set screw to keep the wheel
attached to the gear.
Lower Fairing Installation
1. Prepare the lower wing fairing by drilling the
indentations at the rear of the fairing for the wing
bolts using a 1/4" [6mm] drill bit. Cut a notch in the
front of the fairing to allow for clearance of the
center ribs on the wing.
Note: If you plan on installing a tuned pipe, use 6-
minute epoxy to glue the hardwood mount to the
lower wing fairing.
2. Attach the wing using two 4mm bolts.
Position the lower wing fairing onto the bottom of
the wing, and align it with the fuselage. Use 30-minute
epoxy or R/C-56 glue to attach the fairing to the
wing (but not the fuselage!)
Note 1: If you are installing a tuned pipe, remove a
section of the wing covering to glue the hardwood
mount to the wing sheeting. Use 6-minute epoxy to
glue the mount to the wing sheeting.
Note 2: If you are installing retracts, the lower wing
fairing must be trimmed as shown in the photo to
allow for clearance of the wheel wells.
Battery & Receiver Installation
1. Hook up the receiver, switch and battery,
