Here's one I designed and built/flew as an electric pusher and rocket glider in 6mm depron, this weekend I rebuilt one in 9mm which sacrificed some weight at the benefit of increased stiffness, flies great! 41" length, 25" wingspan, 15 oz rtf with 24mm E-6 and E-12 Aerotech rocket motors.

Not a Saab Draken, but I like the name and it was dragon themed with the logo....A new offering soon, 32" long, 25" wingspan, 10.5 oz rtf using 24mm E-6 motors and 2.6" diameter. I wanted something 1950's sci fi or steampunk sort of themed....
