Senza Confini is a 54mm maximum performance rocket designed around the 54/2800 case from Aerotech, for the K250W. It is only 31 inches in length. It features a SUPERSHORT design, Tower-launched design, G12 Fillament wound nose cone, a T1000G Fillament wound Carbon fiber airframe, Dragon plate quasi Isotropic Carbon fiber fins, a custom designed and milled 6061-T6 tailcone, Dual deploy, and an automotive paint job.
With a forward aiframe section swap, Senza can also fly a CTI Pro54-6GXL case.

Alright rocketeers I have a question for you - do you all think that open rocket's center of pressure forecasts are too pessimistic or that RAS forecasts are too optimistic? I know that on burnout I should have a center of gravity location around 21.5 inches from the nose cone. RAS predicts the center of pressure at Mach 3.25 to be more than 28 inches from the nose cone with or without a tail cone. Thats 3 body cal stable at mach 3! I call bullshit on that. Openrocket predicts the center of pressure to be less than 21 inches at Mach 2.4 with a tailcone- Unstable! I am HIGHLY inclined to beleive this rocket will NOT be stable at this speed in this configuration. RAS says "go for it" , OpenRocket says "you better not" . What do YOU say?
Result:
Motor ended up being barely over the L threshold, maybe 2600ns. But fast. It went fast, but not fast enough to answer our question. As i write this now, this flight took place almost six years ago. Today we could make something that would shred the rocket, but she sits retired and safe! She well served her purpose in life, and I am proud of it.
Flight:
Mach 2.7 flight and stable. Fully recovered.
