Descon 2 Heads Up Original Design / Scratch Built

Scratch - Heads Up {Scratch}

Contributed by Bob Fortune

Manufacturer: Scratch

This is basically a tube launched rocket.  It's almost finless but I suppose the fins have some effect.  I don't have VCP so I have no idea how it tapes out. The center of gravity with a B motor is right at the NC-shoulder mounted launch lug which was serendipitous but nice.  Funny how those things work out.

I've flown it on  B4-2's and on C6-3's.  It passes safety inspection as it stands though the motor tube looks a little loose in the aft centering ring.

Typical Scenario:

I show up at the check-in table with a B motor installed.  The RSO says "you're gonna fly that onna B?"  I explain that the yellow body stays on the pad.  He says  "hunh, the body stays on the pad?"  I pull the rocket out of the tube so he can see the configuration.  He says,  "hunh?"  at which point I show him the parachute and shock cord  *inside*  the nosecone.  At which point he scratches his head for a bit then is willing to play along.  He'll call for a heads up, and then lets the crowd know that this is an  "untested rocket so everyone watch out".  Instant audience.  Lotsa laughs, all these people are looking for a large yellow rocket to launch and a black and fluorescent orange arrow-looking thing squirts out.

The thing actually flies really well.  About 600' on a C, kind of wimpy 300' on a B.  It's also relatively inexpensive to make since most of it is BT and foam core board.
