Two words for this design: Nose weight. Love my Bulldog.

Foose,

It was you build thread that originally inspired me to work up the Bulldog in Rocksim. Your Bulldog build looks great! I built one as a teenager but it didn't look anywhere near as good as yours.

How does your Bulldog perform on a single 18mm motor?

I tried to work up a triple 18mm design in Rocksim, but could not get deployment velocity numbers within recommended guidelines.

Bill, thanks! I've never flown it on 18mm. It would probably do ok on a Est.C6-3. I may try adapting it down from 24mm one of these days and see how it does. It came out lighter than I expected, but it's pretty draggy. This model would be a great candidate for a interchangeable mount. I thought about doing that several times during the build, and waited to install the mount until very last minute for that very reason. I knew I'd be flying it one 24mm most of the time anyway, so I glued the mount in. I was a little worried about adding weight to the rear also. I knew it would marginal, but I didn't think a D12 would tip the balance so adversely. It's got 1/2 ounce added in the nose now, and that seems to have worked out. C11-3 is a good motor choice. Not super high, around 400-500, and gives it a nice kick off the pad. Oddly, the cluster never crossed my mind. Two Quest C6-5 would probably work out great!

Talking New RS9 Design: Argent

From the "Comments" section of the attached RockSim 9 file:

"Hold your head up!" This rocket's name is a nod to keyboardist Rod Argent's 1970s rock group and their only hit song.

A surprisingly well performing old-school design using RockSim 9's handy-dandy "pods" feature. <big evil grin>


--Although you *may* want to use a nylon chute, given the 23+ f.p.s deployment on a C6-5.


My supervisor called me this morning and wanted me work a late shift, so this design is a result of my "non-structured" morning.


Cheers,

Nice one, Jay!

I like both the look and the name. A larger body tube on the forward end of rockets has come to be one of my favorite design elements, and I like "Hold Your Head Up," too.

Are the body and pod tubes painted silver (since Argent means silver or white metal)?

Um...

After taking a second look at the RockSim file, the pod tubes are white, and the other tubes are silver/gray. So, basically you can paint them whatever color you'd like!

So yes, your Argent can be argent. If you want it to be.


Gotta go to work now!


Cheers,

Oooohhh! Nice!

I like the color scheme you have in these renderings, Jay. Blue and gray/silver just goes together.

Good numbers, too!

Talking Adding up some more...

On November 26, 2008, I posted:

So if I average it out to one a week, it looks like this:

Week of

Nov. 02 -- XPL Experimental
Nov. 09 -- Doc Boy
Nov. 16 -- 5820 A
Nov. 23 -- 5820 B
Nov. 30 -- 5820 C
Dec. 07 -- 5820 D
Dec. 14 -- 5820 Ugly
Dec. 21 -- SONAR 7

It looks like my score is 8 done, 44 to go for 52 weeks' worth of designs, like Craig is lobbying for.


Some of my newest designs will have to wait for RockSim 9's added features, so those releases will be put on hold temporarily.
Here's the update on my ongoing attempt to keep up:

Dec. 28 -- Premonition
Jan. 4 -- Epsilon 3*
Jan. 11 -- Estes Scamp 1.36X**
Jan. 18 -- Estes Scamp 1.68X**
Jan. 25 -- Argent


*One of the aforementioned "Waiting for RS9" designs.
**Resurrected from 2007(-ish).

It looks like my current score is 13 done, 39 to go for 52 weeks.


Craig and everybody else have been up to their eyeballs with outside projects, as well as generally tidying up. (And a certain scale project that doesn't include dragons shedding their skins. Sorry. That's all I can tell you.)


Cheers,

Thanks! This was another one of those designs where I had the basic outline, and just kept plugging motors in until they worked. ("Okay, 24mm is too much!" [exasperated sigh] "Let's bump the motor mount down to 18mm. --Now, *that's* better!")

(mock disbelief) Are you telling me that Rod Argent's *real* last name was White? Or Silver?


Thanks, guys!

Exclamation New Design -- GSS Horizon

Jay's latest design "Argent" must have struck a chord...

The GSS Horizon follows the same basic pattern, but is smaller and capable of very good performance on the 13mm engines.

Length: 20.90"
Diameter: 1.04" (ST-10)
Fin Span: 5.02"
Weight: 1.24 oz


1/2 A3-2T......98'.......Dv 8 FPS.......36" x 1/8" rod
A10-3T.........306'......Dv 21 FPS......36" x 1/8" rod
A3-4T..........310.......Dv 12 FPS......48" x 3/16" rod


Note carefully the A3-4T line. The model has a very slow acceleration off the rod, and needs a full 40" to reach safe flight V. The A10-3T reaches flight V in 20".

Enjoy!
