Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

User commentsMany years ago, I had a Tercel, which was a very similar hlg from Bridi, with, I think, the same span. I thought it was marginal for hlg*, but it was kind of fun on the slope, especially in 20 to 25 mph wind with a lot of ballast. Very maneuverable then. Lots of fun trying to trace the crest of the dune only two or three feet away from it while going really fast. Not a good time to sneeze, but the wind chill was pretty bad. As I recall, everyone else waited in the car. Perhaps it would have been better for hlg with a somewhat thinner airfoil. *If memory serves, Tom Keasling had one also, and his would catch thermals more often than mine. Couldn't be a case of pilot skill, could it? Must have been some kind of unobtainium he used.

Hi Steve. Maybe I'm committing a betrayal to the old spirit of aeromodelling, but I've developed a 3D printed version of the hand-launched glider Flipper (oz4994). Anyway, I send you a pair of photos [more pics 004,005]. Adding injury to insult, the polyhedral angles were too much for my flying ability. After a few spiral dive crashes, I reduce them to 5 (interior) and 3 (exterior) degrees. There are some videos and a few more photos in my Instagram page https://www.instagram.com/cp_aereo/
Thanks a lot for your web. It's an incredible work and a treasure.
Yours, Angel Pradel.

* 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.
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.
