Default Pattern plane repair

A friend of mine gave me this airplane the other day when my primary pattern plane went in. This plane wasn't crashed, it got broken while sitting in his plane-carrying trailer. Here's what it looked like when I got it from him.

I mixed up some West System resin and put the two halves together. Here it is while setting up. I used masking tape to hold the two pieces in place.

Here it is after the epoxy had set. I put strips of fiberglass cloth on the inside of the fuse using some more resin to give the joint additional strenth. Paint repair will be done by someone else so it'll probably be at least a few weeks before that gets taken care of.

The airplane is a Patriot 3D. The 3D is a version designation, not an indication of 3D capability.

At this point I'd run some additional hardwood stringers inside, or press flat thin thin hardwood on top of your fiberglass for structural integrity joining the break. I don't think cloth on a clean break is enough.

WestCoast: The cloth will be enough. I used very slow-drying laminating epoxy so that it would penetrate the wood. The break is stronger than the original wood structure. I checked with the designer/builder of the airplane before I started, he said the glass would be plenty enough. Probably gonna re-glass the outside too on the side that the break was really bad.

aerowoof: Thanks.
