Exclamation New Plan -- BarJet 3524

OK, here's one that's a little more serious in nature. Using those Mercury Engineering components, I applied a full measure of force in motors to reach a full mile in altitude. It jumps off the pad and reaches stable flight velocity in 13", so a minimum 36" x 1/4" rod is required. A 48" x 1/4" rod would give it more support, though.

Length: 61.875"
Diameter: 3.0"
Fin Span: 12.0"
Weight: 19.77 oz
Parachute: 36" Rip-Stop Nylon

(5) G55-10......5000'......Dv 23 FPS......36" x 1/4" rod
(5) G37-10......5321'......Dv 20 FPS......36" x 1/4" rod

More foo for thought...


PS -- Whoever builds this bird owes us all some flight shots!
