Didn't Carl say he wasn't going to sell any motors?

New Design -- IQSY Tomahawk
OK, here's the next installment in the series. This one really needs Carl's "propulsion units" to fly right.
Length: 19.63" Diameter: 0.908" (ST-8) Fin Span: 3.66" Weight: 1.04 oz 1/2 A6-3......115'......Dv 16 FPS 3/4 A6-4......213'......Dv 22 FPS A8-3..........287'......Dv 19 FPS B4-4..........643'......Dv 33 FPS......Not Recommended! B6-4..........648'......Dv 38 FPS......Not Recommended! B8-6..........768'......Dv 13 FPS B4-5..........768'......Dv 4 FPS B6-6..........783'......Dv 18 FPS C6-5Q........1289'......Dv 35 FPS......Not Recommended! C6-7.........1334'......Dv 27 FPS......Not Recommended! I'm looking at the DRT next. The tail section is going to be the challenging issue of the build. Enjoy!

New Design -- D-Region Tomahawk
I simplified the tail quite a bit -- by not putting all of that detail into the simulation to begin with. This model has also uncovered another RockSim 9 bug that I'll have to say something to Tim about.

New Plan -- WAC Corporal (single-stage version)
This is the upper section of the vehicle, for sport flying. It has really nice performance, but only on those special "propulsion units" that only exist right now on paper.
Length: 19.40" Diameter: 1.17" (ST-11) Fin Span: 4.80" (RKT file shows something crazy: 8.564". Clearly a bug.) Weight: 1.1 oz All simulations use a standard 36" x 1/8" rod. Last column shows which manufacturer's data is being used. 1/2 A6-2......104'......Dv 13 FPS......Semroc A4-3R.........139'......Dv 12 FPS......Semroc 3/4 A6-3......195'......Dv 5 FPS.......Semroc A8-3..........263'......Dv 13 FPS......Estes A8-4..........264'......Dv 19 FPS......Semroc (using Estes data) 3/4 B7-5......524'......Dv 11 FPS......Semroc B4-4..........586'......Dv 24 FPS......Estes B4-5..........591'......Dv 10 FPS......Semroc (using Estes data) B6-4..........592'......Dv 28 FPS......Estes B6-5..........599'......Dv 6 FPS.......Semroc (using Estes data) B8-5..........692'......Dv 10 FPS......Semroc B4-5..........695'......Dv 7 FPS.......Semroc B6-5..........707'......Dv 5 FPS.......Semroc 3/4 C19-6.....978'......Dv 4 FPS.......Semroc C6-5.........1197'......Dv 26 FPS......Estes C6-6.........1203'......Dv 8 FPS.......Semroc (using Estes data) C6-6.........1267'......Dv 8 FPS.......Semroc This model may require a revision, due to the bug in the fin measurement value. I've sent a copy of this design (minus all of the Semroc data and references, of course ) to TVM and PF up at Apogee to see what they say about it. Enjoy!

WAC Corporal fins
For anyone thinking about building a model, keep this note in mind: There is NO bevel in the fins! They are quite nicely aerodynamic in shape, as can be seen in this photo. Although this shows a Bumper WAC, the fins are constructed the same on the basic WAC.

Revised Design -- WAC Corporal with Tiny Tim booster
This model was just meant for Carl's 3/4-power core-bore B and C booster engines. I was able to stick with 18mm power in both stages, and all of the Dv's are well under 20 FPS. Sixty percent of the flights come in under 10 FPS.
The downside? Building that interface between the booster and the WAC. I drew it with an HTC-7B coupler to slip over the sustainer engine tube (which is probably enough), and with a half inch of the rods pushed into pockets in the rear transition of the WAC. The real booster worked this way (sort of - they didn't have a large HTC-7B coupler with two vent holes on the real one). For simplicity, I used the same ST-11 tube for the booster. The truth is, the ST-11 is true-scale for the booster, but slightly small for the WAC. Close enough, though, for this Deci-Scale program. Length: 28.88" Diameter: 1.25" (Transition rim; Body Tubes ST-11) Fin Span: 5.20" (RockSim is whacked out with 8.564" -- pending reply from TVM) Weight: 2.01 oz All engines are from Semroc private data. All launch rods 36" x 1/8". 3/4 B7-0 / 1/2 A6-4........446'......Dv 12 FPS 3/4 B7-0 / A4-4R...........485'......Dv 14 FPS 3/4 B7-0 / A5-5............644'......Dv 5 FPS 3/4 B7-0 / 3/4 B7-6........819'......Dv 14 FPS 3/4 C19-0 / 3/4 B7-6......1050'......Dv 4 FPS 3/4 C19-0 / B4-6..........1194'......Dv 11 FPS 3/4 C19-0 / B6-6..........1204'......Dv 3 FPS 3/4 C19-0 / B3-6R.........1229'......Dv 7 FPS 3/4 C19-0 / 3/4 C6-6......1464'......Dv 8 FPS 3/4 C19-0 / C6-6..........1675'......Dv 5 FPS Enjoy!

I'm suspicious that the photo is really a Bumper-WAC. I know that's what Coker said on his website, and there is a V-2 in the background, the info I have says the WAC fin planeform is highly modified on the Bumper shots. Regardless, it is true that the WAC Corporal fins are not beveled. The photo that suggested that many years ago gave the illusion there was a bevel.

New Design -- IRIS
Here's the single-stage version for sport flying. I'm a bit disappointed in the performance, however. Anything over a 2 or 3 second delay results in the model going into the death-dive before deployment. It also needs those core-bores to get off the pad at all, unless you jump to the D12...
Length: 23.81" Diameter: 1.17" (ST-11) Fin Span: 4.714" Weight: 1.34 oz All simulations use 36" x 1/8" rod. A8-2........122'......Dv 5 FPS B16-3R......201'......Dv 14 FPS B14-3.......205'......Dv 16 FPS B8-3........211'......Dv 19 FPS B4-2........230'......Dv 2 FPS D12-3.......526'......Dv 9 FPS Enjoy!

There was something in the text that said the appearance came from the way the metal was polished, or painted, and how the sunlight was reflected off of it. However, if you look at the root edge of that Bumper-WAC fin, you clearly see a smooth curve from LE to TE. One thing I noticed, the paint and finish on my models looks a ton better than their real ones...
