Oh Man here we go....I build 'em all, even a few ARF's over the years. Try building a Clark Spitfire with a "Glass Fuse". That one took me longer than it took to get my 13 foot Corsair in the air. Or my (Frankenschmidt) Me109, with an American Eagle "Glass Fuse" and an enlarged wood wing plan from Claude Baskin plans and tail section from a Dave Platt plans. Trust me the glass fuse saved only a small fraction of time on the fuse, but I made it up on the time I spent creating the rest of it. I had to set the wing and tail incidence on that one purely from experience. You may want to re-think that one "Glass Fuse" statement for sure. Above poster make a good point on the Yellow Kits as well, I have "BUILT" 5 of those. I make no comments good or bad concerning ARF's, rather only that I do not typically take to them myself. I think you lit the fuse. Hornplayer may have nailed it in his opening salvo:
