❏ ❏ 23. Connect the clevis to the control horn. Center the
aileron and the servo arm. Mark the pushrod where it
crosses the servo arm. Bend the pushrod and connect it to
the servo arm with a nylon Faslink. Trim the excess wire
that protrudes past the nylon Faslink.

1. Trim one matching set of wheel pant halves along
the molded cut lines. Notice that the top of the outer pant
goes over the lip of the inner pant and the bottom of the
inner pant goes over the lip of the outer pant. You can use
a hobby knife to carefully score along the cut lines and flex
the plastic until the excess breaks free, or use small
scissors to cut along the lines. Hobbico curved tip canopy
scissors (HCAR0667) work extremely well for this and
make the job a cinch. For now, don’t worry about accurately
cutting out the opening in each wheel pant half–just cut an
approximate opening for the wheels.

2. Use your bar sander to carefully true the edges of
the overlapping pieces of the wheel pant halves so when
you glue them together the seam will be as small and
straight as possible. Notice that the front and rear of the
wheel pant halves do not overlap and are “butt glued”
together. Use 150 or 220-grit sandpaper to remove the
flashing and thoroughly roughen all areas that are to be
glued including the indentation on the inside of both inner
wheel pant halves.
❏ ❏
3. Test fit the wheel pant halves and make adjustments
where necessary for the best possible fit.
❏ ❏
4. Join two wheel pant halves and carefully spot glue
them together in just a few places with thin CA. Start by
spot gluing the top, then the front and rear where the two
halves just butt together. After the halves are joined,
securely glue them together along all the seams with thin
CA. Note: Do not use CA accelerator on the ABS plastic as
it may develop cracks and/or keep the paint from adhering.

5. Use your hobby knife or a Dremel ® Moto-Tool ™ with
a sanding drum to cut out the wheel openings. Hint: Make
the wheel openings wide as this will make installing the
wheels and axles easier and cause less interference with
the wheels upon landing and takeoff. You can see the size
of the wheel openings in the following photo.

6. Use medium CA to glue the die-cut 1/8" plywood
wheel pant mounts to the inside of each wheel pant.
