INSTALL THE COWL

❏

1. Sand a bevel on one end of each of the four 10 x 25mm

cowl ring dowels. We found putting the dowels in a drill and

using a sanding bar with coarse sandpaper makes beveling

the dowels easy.

❏

2. Insert the bevel end of the cowl ring dowels in the front

of the fuselage. They should  t well but not be dif cult to

insert or remove. If they are tight, wrap a piece of sandpaper

around the shaft of a screwdriver or brass tube and enlarge

the hole slightly.

❏

3. Test  t the plywood cowl ring on the dowels to check

alignment.

❏

4. Once satis ed with the  t, use 6-minute epoxy to glue

the dowels in the cowl ring. Keep the cowl ring and dowels on

the front of the fuselage for proper alignment while the epoxy

cures. A piece of masking tape over the holes will keep the

dowels  ush with the front of the cowl ring. Caution: Make

sure to leave a slight gap between the cowl ring and the front

of the fuselage to avoid gluing them together.

❏

5. Cut out the center of the dummy engine to clear the

drive washer of the gas engine. If the RimFire 65 motor is

installed, the hole will need to be enlarged as shown.

❏

6. If a gas engine is installed, cut two openings between

the cylinders for cooling.
