I was cleaning out stuff in storage awhile ago...and had boxes of old Loc Precision parts.
Lots of BT, CR, some partial kits that I had pirated for parts for other builds (a Loc Forte kit or two), tube couplers and some home made ply fins from about 8 years ago, and a few custom made CR and bulkheads I inherited.
Loc P. parts are practically universal...so I got to thinking, rather than letting this stuff gather dust, I could organize the stuff into a project or two.
I had been toying around with doing a project for testing my older GWiz altimeters for doing cluster/airstarts AND staging ...a "test bed" project that I could do either cluster motor airstarts - or staging, on the same rocket, depending on how I set it up.
The GWiz is an accelerometer and barometric unit that can be switched from airstarting to staging simply by pulling one jumper on the board.
Gwiz unit in the sustainer would ignite the second stage on burnout of a single motor in the booster....or...
with a second Gwiz in the booster interstage Av Bay..., I could do both cluster ignition on first motion, and staging on burnout, on the same rocket, at the same time.
DD on the sustainer...the Avbay in the sustainer could trigger the second stage ignition - if not used for the cluster airstart in the booster outboards.....
So the first of the two projects is a Sport Scale "kinda" like a Terrier - Nike - Orion - with a 4 inch dia. cluster booster and a 2.6 inch dia. second stage sustainer.
Here's the parts pile I cobbled together for that one.
