This is a pack of two AeroTech 29mm F42-4T SU Econojet Rocket Motors. Fly "F" for less! These medium burn, short delay, F-class EconoJet composite motors are a less expensive alternative to the F50 and will push an Aerotech Initiator to 770 ft!
AeroTech established its position as the leader in hobby rocket motor technology with its single-use composite motors. Hobby rocketry has come to depend on AeroTech single-use motors for sport and competition flying. All AeroTech single-use rocket motors have been certified by the National Association of Rocketry (NAR) or the Tripoli Rocketry Association (TRA).
The “Econojet” line of single-use motors combine performance, design and packaging in a line of motors that could be sold at a price point midway between its traditional single-use motors and RMS reload kits.
Motor Effects; Blue Thunder™ (T): Produces a bright violet-blue flame with a minimum of exhaust smoke. These motors provide a higher level of thrust than White Lightning or Black Jack motors of the same total impulse. Blue Thunder is the perfect propellant for high lift-off acceleration.
