Aerotech F20-4W  <br />29mm Econojet for MPR

F impulse Single Use APCP motor for Mid Power Rocketry

PRE-ORDER NOW for fastest delivery

AeroTech's single-use composite model rocket motors are offered in over 30 different combinations of physical size, power, burn time, propellant type and delay length. All rocket motors are certified by the National Association of Rocketry, and all use the exclusive Copperhead single lead igniter.

The W in the motor designation stands for White Lightning - a low smoke, fast burn propellant formulation. You get a crackling sound effect, too!

The new Econojets are completely redesigned and utilize a one-piece molded glass-phenolic case and nozzle unit with a matching molded bulkhead. The bulkhead is retained in the case with a threaded joint, and a small amount of adhesive is used to seal the interface. Motor hook recesses are molded into the nozzle end of the case.

Another new feature is a plastic ejection charge retaining cap in the forward bulkhead. The cap retains the ejection charge in the bulkhead much more securely than in the previous design.
