Airframe Couplers

Airframe couplers (also called tube couplers, connectors or joiners) are used to join tubes of equal size to make a longer rocket. These couplers are hollow to allow air to flow through them.

Frequently Asked Questions about the Aerotech Initiator kit:

Q. Can Airframe Couplers be blocked off and used to make payload bays for small rockets?

A. Yes. See our free YouTube video that will show you the steps to make your own payload bay from the tube couplers shown on this page. If you are on a budget, this is a much cheaper way to make them versus using a balsa nose block.

Related Items and Optional Accessories That Go Great With These:
Balsa Bulkheads

Balsa Nose Blocks, also known as solid bulkheads or tube connectors are used to make payload bays for model rockets. They block off the air flowing through the tube, protecting the delicate payload from the heat of the ejection charge. All you need is a screw eye to attach the shock cord or parachute, and you're ready to go.

Tube Couplers For Large Diameter Rockets

These regular Kraft-paper couplers fit the same tubes as the Blue Tube Couplers. So if we're out of a size of the Blue Coupler you need, this could be an alternative you may want to consider.

Tube Couplers for High Power Rockets

Actual Customer Comment:
"I am so pleased right now, I can't even tell you. Thank you so much for taking the time to look at my account and finding that I had already ordered the product. And rather than just blowing me off, you sent a copy of it and reminded me that I did in fact have it already. Thank you for caring enough to do that. It makes me loyal to your company for my rocket needs. I really appreciate your customer service!" -- Blake Goddard
