RE: Great Planes 25% Yak 81" 12-lb, seen on Fly3D Magazine
Okay guys, here's a picture I took today. As you all can clearly see, the firewall sides are suspiciously clean of glue... IF there were glue, the would also be schreds of wood stuck to the sides. (Or correctly: If there were glue, my plane would still be flying...) Now here's what I believe happened: The firewall sides gave up the struggle to keep the enginebox together, since the triangular pieces were not properly glued to the sides. And when the last bit of adhesion was lost, the box sides just opened up, and my Saito 220 took a short, but rather spectacular burst forward.
