Wings

The wings came pre-built in thr fast build kit but this doesn"t mean there was no work needed.

Mounting Bolt Holes

To mount the wings to the strake takes three bolts on each wing. In order to get the bolt to the mounting bushing you must cut a hole in the top and bottom of each wing. Mark a line across the top and bottom of the wing square with the mounting bushing. Cut a 2.25" hole 5 inches back from the face of the mounting bushing on the square mark. Remove the foam from the hole at an angle to the back of the mounting bushing. Repeat for the other mounting holes. Glass the inside of each hole with a layer of micro-ballons and 2 bid fiberglass.

Wing Installation

Lift wing into place. Becareful not to damage the outer edge of the strake as the wing gets close. Mark the outer edge of the strake where the wing needs to be to attach. Cut the strake on this line. Tape a thin piece of plywood across the outer edge of the strake. This will keep the wing from striking the strake as the wing is installed. Run the bolts through the holes and place the washers and nut on the end and bolt tight 40lbs. Check the wing incodence with the incodence gauge. Adjust the angle of the wing with shims between the strake and wing bushings.

Wing Joint

Create a smooth joint between the wing and strake. Fill the area with foam. Duct tape the end of the strake to keep fiberglass from sticking to it. Sand the foam to fit the curve of the wing by taping sand paper to the wing and running the foam across it till it fit. Glass the foam in place with micro-glass.

 

Sand the top of the foam to fit 1/4 below the joint. Apply 3 bid fiberglass. Finish with frosting and sand to shape. To remove the wing mark a

 line between the wing and strake strut with a chalk line. Draw a line between the tip of the strake and the wing. Cut this line with a hacksaw blade and straight edge.
