Sparrow (oz3756)
About this Plan
Sparrow HLG. Chuck glider.
Quote from the designer: "This model was designed as a first model as part of a 10 week model building course which a couple of friends and I put on at local schools for several years. This model could be built and flown on the first night and gave the kids a practical and functional flier after one session of building. Unfortunately the introduction of ultra cheap R/C ready to fly models has eroded the interest in actually building models and the course has been discontinued."
Corrections?
Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

Hi, My four and a half year old son wanted to build a model airplane, so we build this. His contribution was to cut the fuselage to length with a small hacksaw and glue the parts together, while I merely cut out the parts and slightly improved the alignment of the wing and stab after gluing. I think this must be the simplest possible model airplane you can build out of balsa, and it turned out to fly quite well. Unfortunately, we only had quite soft balsa available for the fuselage, and the need for reinforcing became evident after a few flights… Regards,ChristianHusvik - 14/06/2013
I shrunk one of these to 10 inches, and added a hook to make it a catapult glider. As is usually the case when I want high launches, trimming was a bit fiddly. I added a "Budd kicker", which helped. One time, I launched into a thermal and had a flight over two minutes, even though it never got very high. Fortunately, I'd launched at the upwind end of a sod farm. I had to walk for several minutes, but at least it was on the short grass and I didn't have to search for it. The model eventually died, because I was keeping it in the car all the time, flying it now and then. I should have used a box.

Notes
* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
Scaling
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
