Draw a centerline down the center of the sewer lid. 1" away from the edge, and 2" away from the centerline, drill a 3/8" hole. That will leave you with two 3/8" holes, 4" apart, on opposite sides of the lid. Purchase a pair of 4" u bolts, with 4 large washers and 4 stop nuts. Use the U bolts, washers, and nuts to attach the lid to the bottom of the fuse. Take care not to over tighten the U bolts or you will crack the fuselage. If the only lid you have is 1" thick or larger, you will need to grind away the trailer edge enough for ground clearance. If you are ambitious, you can cut away the left and right trailing edges, and use them for auxiliary inboard elevators. You will need to glue the servos directly to the lid, or drill and top 4-40 holes for mounting. If you find the lid is too much tail weight, you can drill 1" lightening holes until you find the right balance for your flying style.

Good luck,and let us know how it turns out. Pictures would be appreciated for other Ultra Stick lite owners.
