Helicopter Recovery Rockets

Dave Leininger out of Minnesota has built about an 8 foot tall upscale of the Estes Skywinder. It flew at LDRS 2002 in Texas and again at LDRS 2003 in Argonia, Kansas. The rocket was destroyed in a crash at LDRS 2003 when the nosecone seperated and the weight required for the rotors to spin was lost.

Dave is currently making a large upscale of a Gyroc.

Hi,

For a couple of cool project that exercises your craftsmanship and has historical significance, check out the Kopter plans at:

RK08 is a helicopter recover rocket. RK07 and RK13 describe a pretty big boost glider with a helicopter recovery nose. Both of these design concepts successfully earned patents back in the mid-1970's.

Also, explore the NAR website. They have a set of helicopter recovery plans in their plan collection.

Those rockets look *very* familiar. Weren't those pre Competition Model Rockets?

FlisKits hope to have our first helicopter rocket out later this year. The "T2-G.R.I.P" (Tempest 2 - Gyro Recovery Implementation Package")... :)

It will be a sport model similar to the GYROC but with 3 fins *and* it retains the motor for the entire flight as opposed to kicking it like the Gyroc does.

From what I can gather by viewing the patent dates and checking out the catalogs at Ninfinger, I suspect not. Ninfinger has CMR catalogs dated at 1972 and 1987, but the Kopter patents are dated 1975 and 1976.
