Hi Jay, I've been through a few Mini's and the wing retaining peg has been a more or less constant source of trouble - any ME pilot will tell you similar stories. The problem is that with any undue stress the fuselage splits at the peg position, allowing the fuselage to deform and for cracks to propagate elsewhere.
Stengthening with glass/carbon under the bridge has not worked for me. What I do now is (1) epoxy a semicircle of hard balsa about 1/4 - 3/8 inch thick immediately under the bridge to prevent the fuselage from splitting and to spread the load to the fuse sides. (2) remove steel peg altother, and fill in the hole with epoxy/microballons. Drill a hole in the wing for a second 3mm nylon wing hold down bolt just at the rear of the old steel peg. The bolt screws into a blind nut fixed to a 1/16 ply plate. the plate is glued under the wings seat, the existing flang prevents it from being pulled out. The bolt stands proud - I guess it could be counersunk but it doesn't bother me - anyway you can't see it when it's flying:) I have had no further trouble since. Hope this makes sense. - Mike > From: "Jay Decker" <[EMAIL PROTECTED]> > Got a little to wild with my Muller Mini-Ellipse in big air and broke > the front wing hold-down.
