1. Slide the 10mm x 31” spar through the body and wing half. Leave a 2 inch gap. Slide a 27" 10mm spar into the leading edge of the wing so it barely

protrudes from the root of the wing.

2. Apply CA to the wing root and spray the body with CA activator. Do not glue the spar yet.

3. Quickly slide the wing to the body and push the leading edge spar into the body to align the parts. Hold together until the CA cures.

4. Do both sides.

5. Place your UAV Mapper on its back and drip CA into the spar grooves, then spray with CA activator.

Install the Coroplast center section

1. Test fit the Coroplast center so the camera circle is offset right when looking at the bottom of the plane – see photo.

2. Liberally apply medium CA to the bottom foam body.

3. Spray Coroplast center with CA activator.

4. Carefully and quickly align Coroplast center on the foam body.

5. Press very firmly until the CA cures.

6. Carefully warm the Coroplast with a heat gun and fold it over.

7. Liberally apply medium CA to the top of foam body and CA accelerator to the Coroplast.

8. Carefully and quickly push over and align the Coroplast. Press very firmly until CA cures.

1. Glue a GPS/Compass mount to the right wing. Do both wings if you're adding a second GPS.

Install the servo bottom covers

1. Apply medium CA on the foam wing 1/2" wide around the perimeter of the servo cutout hole and spray CA accelerator on the Coroplast.

2. Leave a 1/4" gap between the two cut outs to allow the servo lead to pass through.

3. Do both sides.

Install the servo mounts

1. Glue the sides on with medium CA.

Note: Rectangle opening goes on bottom.

2. Glue the top and bottom with medium CA.

3. Test fit the motor mount in the cut out in the rear of the plane.

4. Apply medium CA to the motor mount where it will contact the plane. Do not us CA accelerator.
