Speedster Wing Tips
Denney Aerocraft Company
Aerocraft Company has found that a number of Speedster style wing tips
have the potential to separate at the seam where the top and bottom
halves join together. Because of the way that these few were
manufactured there is not enough overlap of cloth on the inside of the
recommend that each builder with this style of wing tip, reinforce this
seam by using the supplied resin and cloth tape on the inside surface of
the seam. The tape should overlap one inch on each side of the joint.
This will assure that a separation does not occur.
Prepare the inside surface by sanding the joint area with 80 grit sandpaper. Exercise caution to prevent injury from exposed fiberglass slivers in this area. Apply the supplied resin with a 2” brush. When applying the tape, insure that all the air is worked out from underneath the cloth. Extend the joint reinforcement as far aft as possible.
