I'm not sure how to label these things: designs that mimic a scale look, but do not represent actual missiles like one may see in the real world

I'm not talking about Sport Scale (the NAR event) because those are intended to represent actual rockets.

Some examples are North Coast Rocketry's Bounty Hunter and Lance Delta, Estes's SLV, or Quest's Minotaur.

Do any of you ever scratch build your own scale-like designs?

If so, would you share a pic or two?

The rocket is a sports scale somewhere in the area of 1/32 scale X-15. (x-15-1)
As you can see it's a rough prototype built to get the proportions some what right (or I think) X-15 look. Now the really good thing about it is it flies like a dream. From the first flight till today's flight #10 it has performed straight and stable from day one. I have never had a scratch built rocket fly so good. I have used only a D12-5 in it. It weighs in at 7.2oz flight ready. Low to no wind 5 to 10 MPH. It has a nice slow but straight lift off and it picks up speed but not so fast that you have a hard time following it. Just guessing I would say it reaches somewhere between 200 to over 225 feet and beyond.
So far the 5-second delay allows the rocket to cost and release the 18'' parachute at the peak of its flight. After today's flight, the shock cord is starting to show burn wear and I know soon it will go. The second prototype I'm building (X-15-2) I'm installing a baffle in it to cut down on the hot gasses. It well gets a black paint job and some markings. I hope this one flies as good as the first portype does. Of course, I'm thinking of doing a Delta wing version after this one.

Here's my very rough cut at the Caspian Sea Monster ekranoplan, the Chesapeake Sea Monster.

Nice work, I like X-15's. What are the strake coverings paper posteboard balsa?

Rich, I use a Matte Photo Paper produced by Canon. It's a photo paper made for arts and crafts. A lot of paper modeler use it for building paper models.
The paper weight is 45lb. So far I really like working with it. I get it at Staples or you can get it on the net. It's in a red box.

It's a beaut! Even better, it's apparently very stable even with all that fin & strake area.

Thanks, Rtkman, Yes, it has performed great. I hope my second one is as good. The second one is taking more time to build because I'm adding some improvements to it. If it flys as good I might do a build thread.
Like I said if the second one fly's good I will move on to trying to build a Delta wing version.

Pseudo scale are some of my favorite models to build because I get to do all of the fiddly little detail stuff but don't have to worry about being particularly accurate! Most of mine are actually pseudo-scale, meaning that they are not models that represent anything real, but look like they could be.

Here are a few pics:

This one started as an Estes Majestic and was modded to look like a Nike based sounding rocket of some kind.

This one is a mid-power designed to look like a Scout-type launch vehicle.

Another imaginary sounding rocket. It started out as an Estes booster-55!

There are a couple more I'll put in another post....

A couple more:

Imagine a secret Air Force sub-orbital, hypersonic recon ship. It would be launched on a central liquid booster with two solid boosters and recovered at any one of several bases around the world. This version flies on a central 18mm and two 13mm boosters and generally recovers at the same field it was launched from.:p It was built over 15 years ago and is still flying. The lifting body glider flies really well but is tricky to trim.

I like building true scale models too, but I think the fakes are my favorites!

Super impressive! I especially like those "rivets" and "id and instructional text" on the lower body.

Superb! That lifting body design is incredibly realistic, and the best part is that it's also a successfully functional glider.

YESYES!

Thank you Mike, that's precisely the kind of examples I was looking for.

Fake Scale could be a great HPR sport event at NARAM or NSL, for scale looking rockets that wouldn't be in concept scale or sport scale. The only rules: 1) looks scale but isn't. 2) Uses an M motor or less. 3) Most awesome wins.

I seem to remember that Estes used to call those Fantasy Scale in the catalog.

I thought Fantasy Scale was more about scale or semi-scale models of fictitious subjects, like a Colonial Viper? I though this thread is more about bashing sorta scale versions of real rockets?

No, LW specifically said scale looking models that don't represent a real rocket.

You may be correct about the meaning of "fantasy scale" though; I'm not really sure.

Estes calls the Nike-X "scale-like", although that model is clearly inspired by the Nike Zeus if I remember correctly. The Shrockets Sea Sting is a perfect example of what LW was talking about, although Apogee doesn't use any particular term for it.

I think I am right about half of the jibberish I spout.

Thanks Daddy. Some inspiring examples.

I am really curious about that last entry. What is going on in the tail section? I can't see enough detail to figure it out.

That was my attempt at what I called Gas Dynamic Stabilization. What ever the name read up about it here on the forum, the guys will perfect it soon enough. No more fins! Little or no nose weight! No launch rods, scale Minuteman Missiles flying straight up every time!

Nothing to look at, really. But once it blows up, who cares.:wink:

Hey Daddy is that Gas Dynamic Stabilized rocket also a mulit-stager? Even a successfully working single stager is pretty impressive!).
