C. Remove the engine from the engine mount and the
mount from the fuse. Use a drill press, if you have one,
to drill a 1/16" pilot hole at each dimple. If you do not
have a drill press, use a hand drill making sure the
holes are perpendicular to the engine mount beams.
D. Use a 7/64" drill bit to enlarge each hole.
E. Reinstall the engine mount on the fuse. Mount the
engine on the engine mount with four #6 x 3/4" sheet
metal screws. Hint: Rub the screw threads on a bar of
soap before threading them into the engine mount.
They will thread in much easier.
Optional: Modelers who prefer to mount their engines
with machine screws instead of sheet metal screws
should drill the engine mounting holes with a #36 drill
and tap the holes with a 6-32 tap. 6-32 x 3/4"
machine screws (not included) are recommended.
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 a small scissors to cut
along the cut line. Hobbico curved tip canopy scissors
(HCAR0667) work extremely well. For now, don't worry
about accurately cutting out the opening in each wheel pant
half-just cut an approximate opening for the wheels.
D 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 rear of the pant halves do not
overlap. Roughen all the areas that are to be glued, including
the indentation on the inside of both inner pant halves.
D 5. Roughen a piece of leftover outer pushrod tube.
Insert the outer pushrod tube through the throttle hole in the
firewall. Glue the tube flush with the firewall.
D 3. Test fit the wheel pant halves together and make
adjustments where necessary for the best possible fit.
D 4. Join the wheel pant halves by carefully spot gluing
them with thin CA. Glue the top, the front and then the rear
where the two halves butt together. After the halves are
joined, apply thin CA along the length of all the seams.
Note: Do not use CA accelerator. Use of accelerator on
the ABS plastic may cause cracks and/or prevent paint
from adhering.
D 5. Use your hobby knife or a power tool with a sanding
drum to accurately cut out the wheel opening, testing the fit
of the wheel as you proceed.
Hint: Make the wheel opening wide as this will make
installing the wheel and axle easier and cause less
interference with the wheel upon landing and takeoff. You
can see the size of the wheel opening in the following photo.
We highly recommend that all plastic joints and screw
holes be strengthened with fiberglass cloth (not included)
and thin CA on the inside of the joint.
D 1. Trim one matching set of wheel pant halves along the
embossed cut lines. Notice that the top of the outer pant
D 6. Use medium CA to glue the die-cut 1/8" plywood
wheel pant mount to the inside of each wheel pant.
