Contributed by Tim Fischer


I was asked to lead a small rocket build and launch event.  In preparation for this, I looked at several "Skill Level 1" kits from various manufacturers.  Estes is the usual "obvious" case for such classes, but I was a little unhappy that all of their beginners kits seem to have plastic fin units.  I really wanted to give the kids a taste of working with real wood fins.  As such, I emailed Jim Flis and asked about the possibility of getting one of his Jig-Tech rockets in builk for our class.

If you're not familiar with the Jig-Tech fins, they're really awesome - basically the fins fit together perfectly, and are easilly glued up to make your own fin unit.  So it's sort of the best of both worlds - you get the instant alignment of the plastic fin unit rockets, but the kids get a taste of working with balsa.

Jim steered me toward one of his newer creations, the "DooDad" rocket.  This rocket seemed to fit the bill perfectly - it's a "minimum diameter" rocket (meaning the engine fits right into the body tube), yet it has an engine hook.  This makes for a quicker, easier build than larger body tube rockets, and the kids were excited to find out it would also mean higher flights due to the lower weight and reduced body drag.

Favorite Rockets: Sunward SkyBender


I currently live in Toronto with my family.

The bug got me into the hobby of model rocketry after watching the film October Sky with my 2 children. That led to a launch and further involvement in the hobby. I tend to make and fly model rockets. To me
there in more enjoyment in building kits and flying. I personally don't like spending hours building a scale kit only to lose it on a flight.

I am the Owner of Sunward Aerospace Group Limited which is a maker of high quality model rockets based in Canada. Sunward also makes a line of
products for the Rocketeer and Hobby Stores.

Other hobbies and interests include photography ( 35mm film kind ), gardening, and many things on the geek side.

Model Rocket Building: Peter Alway Saturn IV Build, Part 1, Plans and Parts
This model was from Peter Alway's Home Page. I can't seem to find it now! If anybody has a link, let me know. The website had plenty of sport and scale plans including a Vostok, Saturn I and a Flying Rabbit that looks better than the old Estes Cloud Hopper. You can get Peter Alway's books: Rockets of the World HERE and Scale Bash HERE Both highly recommended! There's one model that has been on my "to-do" list for a while. The SATURN IV! This is Peter's "psuedo-scale" design of a Saturn that could have existed between the Saturn 1 and Saturn V, the Saturn IV. Full resolution plans aren't ...

Model Rocket Building: Asking Permission Might Be A Good Start!
If you follow the blog, you might recognize this rocket. It's my two engine cluster model called the Big Girtha. It was adapted from a Quest Big Betty kit. I took this picture before it was launched at the Tampa TTRA monthly. Then I saw it in a EBAY listing. Maybe I should be flattered, but I'm not. A vendor was selling his 808 "Spy" cameras using my picture. Farther down the Ebay listing is a link to my YouTube video from the flight. I didn't buy and build the rocket, buy the camera, fly it, edit the video and post it for somebody else to make a profit. Build your own model, fly your ...
