Like Viking, my username is also my favorite rocket -- in my case, the Trident. I guess I could have also chosen Orbital Transport. Although I do not fly HPR any longer. I do have all the parts acquired for a 2.3" diameter Trident, including all the nose cones. I really should just build it. I also have a BT-60 based Orbital Transport that is designed for 24mm E/F reloads.

Pretty much the entire '69 Centuri catalog, but if you're wanting a specific rocket, it would be the first rocket I built as a kid; the Astro-1.

Not a favorite, but one I want to make... The Viking.

As a PSU Viking alum, it seems only fitting to recognize my Alma Mater

Launching is Optional... Landing? That Depends on Trees.

This is my HPR 2x upscale but you'll get the idea.

My favorite LPR rocket is not a kit, but rather one I designed myself:
   
The 3-D Printed rocket!

Only 7 parts ,not including the rocket engine, for only $99.99!  What a deal! Tongue

Very nice!  I assume since you mention that it's 7 parts that the fins are printed separately?  How did you attach the fins to the airframe?

From the photograph, it looked to me like the fincan is one single unit, there's an upper airframe, nosecone, a couple of pieces that may be related to motor or parachute retention, parachute, and shock cord.

From what I know about 3D printed parts, I'd hazard a guess that the fincan was printed upright from the bottom to the top.

Thanks!  Fins, motor mount, and lower body tube are all one unit.  The whole thing was one print run (Something on the order of 5Hrs on a older Stratasys Uprint!)

The bottom part is a fincan/motor mount/half motor retention/eyehole.  The other half of the motor retention is the retaining ring that is inserted in the rear and given a quarter twist to lock the motor in.  The rest of the 3-D printed parts include, the nose cone with another eyehole as well as a shoulder, and the top part of the body tube with a shoulder on the bottom.

It was printed standing up, however, the bottom is not flat, so support material had to be printed for it at the same time.  All the parts were printed at the same time.

LPR? 

SO many choices...  Must I settle on just one?

The Estes Goblin is a long-time favorite of mine... I upscaled this for my L2 bird.

The Estes Der Red Max as well... the first scratch-built HPR I made was of this classic.  To 4".  Estes came out with the MDRM a couple years later.  Mine has a 38mm hole, though.  Heh.


The Citation Patriot --that is, NOT the missile-- I've got to say, is the first one I went looking for when I got back into this.  I'll probably do an upscale of it at one point in the future... soon as Stickershock is back up and running...


Later!
