wow, those will be rocket ships!!
here's a picture or 2 of my shrike 10. just finished it before the holidays and will test fly it in the spring. Just went with a magnum 15 on a tuned pipe. i wanted a little more of a jet look so i moved the canopy forward and shortened the hatch slightly. this meant rotating the engine about 135 degrees to run the pipe underneath out of sight. i built a fiberglass belly pan using foam, then glass, then removing the foam. it's very solid and i'm pleased with how it turned out. oh, and behind the stick I modified a williams bros pilot for more of a jet jock look.
