WAC Corporal with Tiny Tim Booster Model Rocket Kit (Two Stage 24mm to 18mm Version)


Price: $39.95 each


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.

Another one of our most popular kits! This detailed model features a balsa boattail, hard balsa nose cone and laser-cut balsa fins. Using the "Pass - Port" staging method, a D12-0 booster fires an 18mm upper stage engine for impressive flights! The upper stage may also be flown as a single stage model. Recommended for the advanced modeler.
