Hi Mike,

I did a leading edge repair similar to that big mouse bite you have near the tip (maybe the size of the palm of your hand), but nothing as extensive as the entire leading edge. I used a carbon rod to set the leading edge and this worked perfectly as you said. I used thick mylar and a set of external braces to mold new skins in place. I am not sure this would work for you because you need areas without damage on both sides of the repair to line the airfoil back up. For the leading airfoil, the first 1/4 of the chord is most critical (or so I have been told). Getting everything back to the right shape and symmetrical could be challenging. I would worry that the 2 sides would not be the same and your trim would change with speed.

Honestly you appear to be an old school modeller, a classic foam core wing could be made to work, copy the layout of an early BVM maverick for the spars, gear plates etc. Modern cores are unreal as the top guys use CNC foam cutters and you can get killer foam now too, not cheap but gorgeous.

In any case, if you have the room, before you throw it out, strip it, pack it up and put it away. You might need something to work on.
