Since I'm blissfully still a kid myself (even if I am 43...) and a batchelor (how could I afford rockets AND a wife?) with NO kids , that reference just whizzes over my head without so much as registering a raised eyebrow.

Do I even WANT to know?

Exclamation New Plan -- Vindicator

OK...

It's black and light green...

Not the highest performer, but probably loud and slow, with lots of latent smoke...

Enjoy!

So if I hack off the second stage, I'll already have a RockSim file for the original Blue Sneek? (which is conspicuous by its absence at BarClone)


Cheers,

Not quite...

There should be a PDF of the original version up on BARCLONE...

The original Blue Sneek used a 12" body tube. I wasn't using RockSim at the time I drew up that version. I created a RKT version much later -- after I had built my prototype. When Scott gets all of the latest updates to YORP and BARCLONE put up on the websites, an updated PDF and a RKT file of the Blue Sneek will be part of it.

I'll put the Blue Sneek RKT file up now, though, for comparison...

A8-3........163'.............10.3 fps
B4-4........436'.............7.9 fps
C6-5........1041'............28.2 fps

Exclamation EIRP #77 Stratos

A question about the stability of this model came up on the OldRockets list, and I wanted to see what the issue was. The model, as described in the plans, is tail-heavy and needs ballast to make it fly correctly.

Attached is a quickie-RKT file minus the tip fins and the elevator. While the tip fins do correct for yaw, the elevator in this simulation would aggravate the negative balance problem. Granted, the simulation is not fully accurate for this reason, but that is a limitation of the current version of the software.

A8-3......218'........3.6 fps
B4-4......531'.......20.5 fps
B6-4......540'.......25.2 fps
C6-5......1151'......32.2 fps
C6-7......1162'......31.4 fps

Funny, now that I see the two versions together... I find I actually prefer the 18" version, but as a single-stager. Kind of a Blue Sneek Stretch.

(Hmm... An entry for the possible Semroc plan book?)
