After totally destroying a multiplex funjet, I used what was left of it to take measurements.
The hardest part of this build was creating and hot cutting the wings. Each wing is built by using symmetrical airfoils that scale down in both cord and thickness as they move toward the wing tip.
Once glued, a carbon spar was laid in for strength. The fuse is simple, just 2″ foam block hot wired to shape. As this foam will not take an impact, I heated a steel rod, and drove it perfectly center down the length of the fuse. This permitted the insertion of a square carbon fiber rod, that will hopefully keep the fuse from breaking on a nose impact.
Power system is currently a Greyson super megajet motor, 6×4 prop and a 40 amp esc.
Maiden will be interesting!
