Swiftest-Highest-Strongest-Greatest

Booster 

My idea is to have a motor system that can be interchangeable in at least two diameters, such as 38/54mm, for a minimum diameter airframe as in the booster, which has a diameter of 2.560" id.  This would allow a model rocketeer a chance to go from a novice  to a NAR or Tripoli  level three certification using one rocket, if there is the desire to, thereby saving time, money and effort.

Well  I did some assuming on my part that a 2.560" airframe would be able to hold a RMS motor that could contain 5120 + Newton-seconds. Wrong!! To get into that class of motors, I need to step up to 75mm motors. This leaves me two options: One - start over with the booster and go to an airframe of 5.380," or Two - build the 2.560" airframe as is, then build a second booster that can handle the 75mm and 98mm motors. I have chosen to take the latter route. 

Update Oct. 28 2000  I have received my parts back from the machine shop and everything fits great. I have epoxied the mother tube screw adapter to  the top of the 54mm MMT and will be epoxying  the MMT into the airframe shortly.

Update Nov. 05 2000 After writing Mr. Waddell at PML  asking when the Terrier booster  kit  for the Mini BBX may be released and receiving his reply ( David, the Terrier booster is still coming along. We had a neat idea for the interstage coupler that we feel is worth delaying the Terrier a little bit longer, but it should be out relatively soon.)  I am going to try my hand it. to see who can come up with the better idea (FORD or CHEVY?) So below is my hen scratching, done  completely in Microsloth's paint program,  that I will give to the machine shop to make from  the  Polypenco Nylon 101 that was used for the other parts as well.
