Another great paper clone from Chris Michielssen…

He has now released his paper clone of the Centuri Bandito. You can find this build and other great clones by Chris in my partial paper rocket section. “Partial”, like most rockets on this page , because it requires a nosecone. The Nose Cone is a Semroc BC-522P. There are some paper nosecones available on this page which can be substituted on some builds (look for Eric Truax’s 13mm nose cone pack near top of the page)

Chris Michielssen has now released his paper clone of the Centuri Hornet. You can find this build and other great clones by Chris in my partial paper rocket section. “Partial”, like most rockets on this page , because it requires a nosecone. Use the 2 3/4” long cone from the Estes NC-20 four pack. There are some paper nosecones available on this page which can be substituted on some builds (look for Eric Truax’s 13mm nose cone pack near top of the page)

Semroc has listed the Spring 2013 collection. Among these is one of my personal favorites the Starship Excalibur. This is a great retro kit from the Estes release in the 1960s. The model is based on the Kit #55 from Estes.

The other releases consist of the Centurion-F, Maxi-Micron and the Booster-18 staging adapter.

As usual Semroc’s quality components shine through in these releases.


I am happy to see Estes re-release one of my favorite rockets of all time – The Sprint. The new release is a bigger meaner Sprint built on a BT 60 tube and using D and E motors and is a tribute to designer Mike Dorfler.

Last year I used a standard Sprint in several NAR contest and won each of them. The efficiency of the design incorporating the elliptical fins and a boat-tail is legendary.

NASA is revisiting an old concept of Copter Recovery for Space capsules(Link here). If you follow some of my rocketry obsessions you would be aware that Copter recovery is very high on the list. See my Copter Recovery Guide for modeler links and info.
In watching some of the new test and looking at vintage research I realized that there were some new modeling opportunities.
I have built a few models with blade recovery capsules and flew them. I called them Teepee Twisters and they were a great deal of fun to fly. But what has caught my eye here is the Vortex Ring Parachute. I would love to find a viable pattern for this chute and reproduce it for a model. If anyone out there has the chute pattern and line configuration let me know. I will continue to study the images in the meantime hoping to create my own pattern to test.

These are two of Ralf Wenderoth’s many designs

Ralf Wenderoth of Germany has been designing some great flyable paper rockets. On many of his designs Ralf includes the Open Rocket data. Today I have added  Ralf’s rockets to the Ultimate Paper Rocket Guide.

New 13mm and MicroMax paper rocket is now available from

Art Applewhite. 

The Pinwheel

It based on the Pinwheel toy I played with as a
kid. We didn’t have X-Box’s back then. :)

(about the MicroMax)The one page file comes with complete instructions and patterns for making 3
complete rockets. Print on light cardstock or heavy bond paper and put together
with Elmer’s glue.” – Art Applewhite

The 13mm has one rocket pattern per page

In honor of today’s successful arrival of the Dragon spacecraft at the ISS  it seemed only natural to build a paper model.

If you follow this blog you know that I have already built a flyable paper model of the Falcon 9.

I found that Ton Noteboom has a great paper model of the Dragon spacecraft on his site.

This 1/48th scale Gemini capsule (Ton Noteboom’s design) was flown to 95,000 feet on a balloon by  JP Aerospace. However this is not the highest one of Ton’s model has been flown.Astronaut John Grunsfeld took a model of Ton’s Hubble up in the space shuttle on Repair Mission 4 to the Hubble.

You can find Ton’s 1/48 and the 1/96 scale of  Gemini-Titan II over at the Lower Hudson Valley Challenger Center Paper E-Gift Shop (scroll down the page of real spacecraft models)

Are you a fan of SpaceX or just a space modeler or rocketeer looking for your next build? Why not build a SpaceX Falcon 9 in time for its first launch to the IIS in April?
You have a options when it comes to the build.

First option is you can buy the official model
made by SpaceX and sold at Amazon


SpaceX’s Falcon 9 kit

Second Option is to build a paper model

The static model is available to download and print from The Lower Hudson Valley Paper Model E-Gift Shop for free. (scroll 3/4 down the page)


You can download the static model and with a few simple conversions make it flyable like I did.
Here is my flyable model:

My Paper flyable Falcon 9

The model can be built using the standard static build and replacing the centering rings with more substantial material. I choose to build the Falcon 9 with Dragon crew capsule. I used foam board with a 13 mm hole used to run a 13 mm tube throughout the length. The rocket separates at the Dragon capsule and successfully flies on 13mm motors. I made the fins from clear plastic to keep the Falcon 9 no fin look.

Third option is to scratch build
See this scratch build here

Which ever option you choose the Falcon 9 makes a great addition to the fleet.

“OpenRocket 1.1.9 has just been released and is available at the normal

For this version Richard Graham has implemented geodetic computation
methods, which take into account the curvature of the Earth,
calculates latitude/longitude/altitude and takes into account the
coriolis effect. The computation method is selected by the “Geodetic
calculations” option in the simulation options. It’s not (yet) a full
spherical computation model, but should be accurate enough for pretty
much all sub-orbital needs.

Doug Pedrick has also enhanced the printing system with the ability to
print fin positioning guides, transition templates and nose cone
profiles. Other smaller enhancements and bug fixes are also included.”

Nice little build instructions over at one of my favorite magazines – MAKE (one of only 2 magazines that  I subscribe to)

Please ignore the safety error of using a fuse and launch electronically according to NAR safety rules.

Here is a new paper Ready-to-Fly rocket from Sergio Moalli. Sergio lives in Varese ( a little city near Milan, Italy). This is Sergio’s first design submitted to the Rocketry Blog. Sergio suggest using heavier cardstock (if my conversions are correct he suggest 110 lb).

Sergio says “My hobby is 3D computer graphics and my passion is build and fly paper model rockets.”

This weekend I launched my hacked version of the Stubby rocket. This static cardstock rocket is as the name implies “stubby” with fins pretty far forward. The challenge was giving this rocket enough stability that it would fly. I began by converting the model to have a BT-5 tube than ran the length of the rocket with centering rings and structure to support. The nose was converted to pop off from the ejection charge revealing a small chute/streamer for a simple active recovery. The nose weight required for stability was fairly substantial for this size paper rocket and moved the CG forward enough to make it marginally stable. The build require quite a bit of alteration to the rear motor assembly to encompass a 13mm Estes motor.

The first flight of Stubby was successful. I flew the Stubby on a 1/2 A-4T which was a little underpowered and caused the rocket to do a slow arc across the sky. Next launch I will use a A-10 which is probably better suited for this build.

Stubby flies!
