Can you launch an RC Space Shuttle on a rocket-powered booster? Here's a project to find out.
In part 1 of this series, we built a space shuttle glider to investigate the principles of lifting body delta wings and then, in part 2, we dropped it from a twin motor science plane to take the project to the next level. In this article, part 3, we're taking it up a notch to prepare for a full-on RC Space Shuttle launch! Here's a video to explain more.
Good news! There are free plans available to download both the Shuttle booster and the Shuttle itself. You can find them here.

The build started with, predictably, a bit of design work. Before you do anything, it's a good idea to get your thoughts and ideas down on paper. Sketch some ideas and then think theoretically about the scientific principals and do some simple maths.
Taking the design to Adobe Illustrator, a fully-realized design for the booster was drawn up. This took the form of a simple side view along with numerous formers to show the thickness of the 'fuselage' fuel tank tube and SRB rocket boosters.
You can learn how to use Adobe Illustrator to design things from Nic Lechner who talked about his design process on a recent Flite Test Podcast episode. Check out this article to find his design series.
The next thing to do was to print off the plans, stick them together and get on with the actual 'building' part of this build!
Formers were cut from Flite Test foam board after being measured and traced from the plans.
Next, a box section was assembled to provide the core of the booster with as much strength as possible.
After this, the box and formers were covered with a skin of card to create a tube.
A nose cone was made in a similar way to the fuselage, just at a tapered angle. Using actual model rocket components may have been an easier way to build this rocket, but it still ended up being highly acceptable whilst affordable.
After a coat of paint, the rocket was really looking like a Space Shuttle Booster!
The paint used was a Rustoleum product. This brand really seems to stick well to both foam and card.
Large fins attached to the booster are designed to counteract the drag of the shuttle on the opposite side of the rocket whilst providing a low center of pressure essential for a stable flight.
The next phase of this project is to construct a high-tech launch pad to enable this machine to blast off into the sky. After that, we'll be go for launch. Make sure to check back on flitetest.com in the near future to see more from this series.
More on Model Rockets
Check out this episode of the Flite Test podcast where we chatted to Joe Barnard from BPS.Space. He's pioneering the next generation of model rockets that work just like the real things - with gimbaling engines and without fins.
