3. Mix up a batch of 6-minute epoxy. Brush epoxy on the

leading edge of each flap and the corresponding trailing

edge of each wing. Glue each flap in the retracted position.

Before the epoxy cures, wipe off the excess with a paper

towel dampened with denatured alcohol.

Fixed Wing Flap (Option 2)

With this option, you can easily add operable flaps later.

❏

1. Identify the four wooden fixed flap retainers shown

here. Rotate the small oval piece until the three holes in that

piece align with the three holes in the larger piece. Glue the

small oval piece to the larger piece. Use the laser-etched

outline and the holes to center the small oval piece. Allow the

glue to dry. Note: The pair that you create will not be mirror

images because both flap servo arms must operate in the

same direction as they exit the wing.

❏

2. Glue the pieces into the flap servo bay covers using

6-minute epoxy. Do not remove the covering. By using

6-minute epoxy, you can heat up the glue joint later and

easily remove the fixed flap retainers to convert to operable

flaps.

❏

3. Trim away the covering from the three small holes.

Install a nylon strap across the two longitudinal holes using

two of the sheetmetal screws included with the straps. Don’t

forget to harden the screw holes with thin CA. Prepare both

servo bay covers.

❏

4. Install the covers onto the wings. Be careful to orient

the covers properly as shown.
