If planning to purchase a kit, the charts in the Specs Page will give you a good idea of how your rocket will perform with a large variety of available motors. There is also a chart that lists the length, diameter, approximate finished weights, chute size, and materials used in each kit. Another popular chart is great for selecting the right parachute for a rocket of a given weight.

THE BASICS: "WHAT FITS WHAT?"
Most of our component part numbers are based on the diameter of the airframe... well sort of. Actually, they are based on the Inside Diameter (ID) of the airframe.
So if you choose to build a rocket using our QT-3.9 airframe, the rocket will have a 3.9" (ID). Simply add the wall thickness x 2 to the ID to get the actual Outside Diameter (OD) of the rocket. Sometimes you'll hear people say "I have a 4" rocket". This is the approximate OD of their rocket.
So now when it comes time to select parts that fit together, just match up the part numbers and you're all set. Here are a few examples...
If you will be using QT-3.9 tubes for your airframe, you will need a CT-3.9 Coupler Tube to join the airframe sections. You will also need a PNC-3.9 Plastic Nosecones, a PS-3.9 Piston System, and CR-3.9-x.x Centering Rings (x.x will be determined by which size motor mount tube you select).
It's that simple!
