Construction notes:

  • The double line at the spine area marks the overlap for sewing.
  • Use some dacron at the Standoffs and Rollbar on the Trailing Edge after sewing on the seam-tape to reinforce that area.
  • Standoff connector positions on Lower Spreader, measured from center of Cross:
    Inner: 26,5 cm. Outer: 31,5 cm.
  • Rollbar connectors are made like this:
    Drill a hole trough the side of the Exel connector large enough to fit a tiewrap. Cut the 7 mm. part at the side so the connector will point backward instead of upwards like the picture. Cut or melt a hole in de Leading Edge dacron as close as possible to the Leading Edge rod. Use tiewrap to fixate the connector.
  • The leechline can be attached to the wingtip nocks or sewed in with the Trailing Edge nylon tape at the tips. Use a piece of bungie cord (knots at both ends) around the center cross and attach the leech line with larkshead knots for easy adjustability (just slide the larkshead knots).
  • curtainweightA curtain weight is used for the the tailweight. Fit it at the end of the tail by sliding it in the velcro pocket and fixate using a tiewrap.
