❑ Set the motor mounting straps and your motor back into place and realign them. ❑ Place the remaining two motor mounting straps over the motor and secure the assembly into place, using four M3 x 12mm wood screws. ☞ Tighten the wood screws firmly, yet evenly, to clamp the motor securely in place. - Page 9 ❑ Cut away the covering material from within the outline you drew, then glue the wing hold-down doubler into place. IMPORTANT Glue does not stick well to covering material. To ensure the strongest bond, always make sure to remove the covering material from the gluing surfaces before gluing the parts together.

Pivot the front of the stabilizer until both of these measurements are equal. ☞ When both of these measurements are equal, you're assured that the stabilizer is square to the wing.
- Page 12 ❑ Apply a generous amount of 5 minute epoxy to the gluing surfaces of both the stabilizer and the fuselage, then push the stabilizer into place and realign it, double-checking all of your measurements once more before the epoxy sets up. Remove any excess epoxy and use T-Pins to hold the stabilizer in place and aligned until the epoxy has fully cured.
