Quantity:




The WAC Corporal was the United States first sounding rocket. Seventeen WAC and WAC B rockets were flown from 1945 to 1947. The WAC was launched with the aid of the Tiny Tim solid propellant booster. After the booster burned out, it fell away and the liquid fuel propelled sustainer stage continued its' upward flight.

This new WAC kit is 1.89" in diameter and just over 2 1/2 feet tall. Comes with hard balsa nose cone and balsa boattail, pre-rounded basswood conduit, and optional laminated fins. Makes a great intro to mid-power rocketry and flies fantastic on 29mm F and G engines!
