FFR VL-2 The FlippiTwin
This rocket is designed to fly on an Aerotech F 29mm Econojet motor
in the first stage and an Estes D12 BP motor in the second. Kit comes
complete with the Flippifin rocket and breech
launcher for single stage flights AND all the components necessary to make
the flameproof yet attractive boosted breech launcher. Builder supplies
their own electronics, we recommend the Gwiz
LC for simplest and best performance.
Boosted Breech Launcher Kit includes:
2 ea. aircraft ply bulkheads
29mm motor mount
2 ea. Motor mount centering rings
Parachute and bridle
Aluminum electronics mounting board
Plus the original FlippiFin kit with ground based breech launcher!
Above you can see how the sustainer with its onboard electronics fits
within the breech launching booster.
What's really cool is you can add any 38mm nose cone to the booster section and have a complete rocket all by itself!
The Story Behind the FlippiFin
It was destined to be tube launched because of the folding fins, and so Bill started researching that possibility and then came up with a great adaptation, breech launched folding fin rockets, where the closed breech can actually increase performance. The first few launches were with D-12's and were a little squirrelly. Besides needing ballast (the fins are heavier than the usual fins) the friction in the tube was high enough to retard the force of the little D-12. He tried booster charges in the breech and gave that up as an imperfect idea. The E-30 flights were great.
The design has subsequently been changed to lighten the aft end of the rocket. The PVC coupler and tube was eliminated in favor of stock kraft tubing throughout. As a result less ballast is necessary for a stable flying vehicle and simulations show a 25% increase in altitude on the E motor. Lightening the airframe has also allowed the use of Estes Black Powder D motors for surprising flights.
