I've never gotten around to buying Rocksim, and all the great designs I've seen on this thread, plus the website, have me getting really close to placing that order. Problem is, I've got lots of old Estes classics to build, some ideas in my head, and all the designs posted here are making the problem get worse, not better!


Thanks Lee, I am glad you like what we have here. The Choice to build, fly or design seems to be a simple one with me lately. If I have the parts, I build, if not I design .

Here is another design I call the Frontier Explorer. I got the illustration from an G. Harry Stine book cover I found on e-bay. The book was called Man and the Space Frontier. Picture too large to post. It is not anything scale, I just gave it a good guess and some major tweeking for stability.

Thanks Again and Enjoy, JP

Exclamation Some new versions of an old kludge...

This set of designs is based on the 3" components just announced in the "Vendors" thread by Mercury Engineering. Their 3" ogive nose cone looked interesting...

I call this set the Big Baby Cherokee D3Mx, where "x" represents the number of 24mm motor tubes in the model.

General specs for all three models:

Length: 28.0"
Diameter" 3.0"
Fin Span: 12.08"

[ADDENDUM: RockSim plugged in a setting of "solid" instead of "hollow" for the nose cone. I didn't catch it until the files were sent. It does change the flight specs quite a bit... ]


D3M1 specs:

Weight: 11.38 oz (no ballast required)

F21W-6......1300'......Dv 1 FPS......48" x 3/16" rod



D3M2 specs:

Weight: 12.03 oz (0.5 oz ballast in tip of NC required)

(2) E30-7.......1710'......Dv 24 FPS......36" x 3/16" rod


D3M3 specs:

Weight: 14.38 oz (3 oz ballast required in tip of NC)

(3) F21W-8......3000'......Dv 34 FPS......36" x 3/16" rod
(3) F72-10......3575'......Dv 15 FPS......36" x 3/16" rod
(3) F32-10......3945'......Dv 7 FPS.......36" x 3/16" rod

Enjoy!

Exclamation New Plan -- BarJet 3524

OK, here's one that's a little more serious in nature. Using those Mercury Engineering components, I applied a full measure of force in motors to reach a full mile in altitude. It jumps off the pad and reaches stable flight velocity in 13", so a minimum 36" x 1/4" rod is required. A 48" x 1/4" rod would give it more support, though.

Length: 61.875"
Diameter: 3.0"
Fin Span: 12.0"
Weight: 19.77 oz
Parachute: 36" Rip-Stop Nylon

(5) G55-10......5000'......Dv 23 FPS......36" x 1/4" rod
(5) G37-10......5321'......Dv 20 FPS......36" x 1/4" rod

More foo for thought...

Enjoy!

PS -- Whoever builds this bird owes us all some flight shots!

My cements eggzactly...

Seriously, though, having a manufacturer of larger components opens up a multitude of possibilities...

Imagine, for example, if we had the SEMROC BC-760 nose cone in 3" diameter hollow poly? My head is spinning about what the Andromeda would look like at that scale...

Let's see...

3" divided by 0.736" equals about 4.08. Now, the current version of the Andromeda is 29.25", multiplied by 4.08 gives us 119.34". The original fin span is 5.86", multiplied by 4.08 would be 23.90" across.

Sounds like I need to work up a RockSim on this bad boy...

Hmm, makes me wonder if Vern got the idea for the Drifter from this design. Except that the Drifter was single BT, its fins and tailcone have a very similar look.

If you are still wondering, check this out and tell me what classic kit this Vintage Sci-Fi magazine cover of Startling Stories has inspired? One of my most favorite kits .

Yeah, Blackhawk, that's the one I was thinkin of .
An upscale of the Blackhawk is a must buy in my book. Do you have a release date yet Mark? Advance Orders??
