  • Aeropack 24mm - 29mm and 29mm - 38mm motor adapters
  • Example of a CTI 24mm motor using a 24mm - 29mm motor adapter to fit a 29mm motor mount Honest John rocket


Aeropack aluminum motor adapters securely mount any motor with a thrust ring like Aerotech composite motors in a larger motor tube.  For example, this allows you to fly a 24mm motor in a 29mm motor tube. The sturdy and lightweight aluminum adapter holds the motor securely by the aft thrust ring. Available to convert the following motors for use in these motor mount sizes:

  • 24mm to 29mm
  • 29mm to 38mm
  • 38mm to 54mm
  • 54mm to 75mm
  • 75mm to 98mm

Generally speaking, it is not advisable to double up adapters--while adapters may (or may not, depending on the fit) be technically capable of nesting one inside the other, it is unlikely that a 24mm motor mount will successfully fly in a rocket heavy enough to be designed with a 38mm motor tube. You'll also have to consider the length of your motor vs. the length of the rocket's motor tube; often, a narrower motor that is powerful enough to fly a rocket with a wider motor tube may be too long to fit inside the rocket. It just depends on each motor/rocket combination.

Warning: 24mm Estes black powder motors can fly in 29mm motor tubes when you use the Estes 24mm - 29mm Motor Adapter. But don't try to use an Aeropack adapter with an Estes black powder motor; without a thrust ring to secure the motor in the adapter, the motor will shoot right out the top of the rocket upon launch!  That's not what you're looking for!

    I like the shorter adapter. This ensures it will fit into some of my short/stubby rockets with short MMTs.
