User commentsHallo Mary, hallo Steve. I think the picture is 30 years old [see more pics 003]. The builder is my friend "Volker Kirch". The Hi-Fly was powered by an electric engine.

Love the Website. Thanks! Hi-Fly? Had one in back in 1975. Fond memories. First flight off bungee? 27 minutes. Way to go. Hint to builders: Keep the wing covering tight, or at high speed the wing-tips will flutter! My Hi-Fly didn't disintegrate, but it was mandatory to re-tighten the solarfilm periodically. It is very tempting to build another.

Hello, I am from Argentina and I am building the vintage Graupner Hi Fly. Here are some photos of the building [more pics 004-007].

I forgot to tell you the model ready to fly weighs 1100 g./39 ounces, and with a .049 Cox engine on a pylon engine mount and a 6x4 propeller about 1200g./42 ounces. I hope the engine can give enough thrust!! Anyway I can tow it.

I had been painting my glider last week, it was my first time at painting a model so it it isn't perfect but it has a good look [model photo & more pics 011, 012]. It's finished now so the next step is: FLY!!! I put Futaba standart servos, FM radio transmitter and a AA battery pack. I hope the weather gets better here, it was so rainy these days. I will fly it in the school with my teacher, an experienced modeler, he helped me with the build of the Hi Fly, there is a big sport field there. In the last photo I am with my teacher [more pics 013].

I am trying to learn to fly rc models. The model is not balanced with the rc equipment only so I had to put some lead in the nose, about 100g. And the Cox .049 is perfect for this glider. My teacher told me that gliders or powered gliders with .049 engines or similar are very easy to fly and learn. It took it very well with a lot of wind........ and I crashed it! It was a really windy day. I crashed it with a wall!!!! I almost crashed a teacher's car! (I was at the school sports field with my teacher.) But I think that I am very lucky because the Hi-Fly didn't have serious breaks. It only broke the left ply dihedral reinforcement and the hard balsa nose block.

* 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.
