Photocopy this plan to give 30 inches span, fuselage 20 inches long, wing rib 4 1/8 inch chord, 2 inches dihedral under each tip. This is the plan from Joe Ott's book and shows the final version.

The flying instructions included this note: “Unless the model carries the weight of the rocket well while gliding, after being launched from the hand, it will not fly unless the rocket has extreme power. Care should be taken that the rocket is not too powerful and will tear the model to pieces during flight.”
