About this Plan

Svenson Fly-Boy. Radio control sport model.

Quote: "Beautiful low-wing aerobatic trainer with racy lines. Semi-symmetrical airfilo enables the low-time pilot to get aquainted with low-wing aircraft and pattern difficulties. Can fly very slowly without stalling. Will accept retracts with very little modification to the wing.

A very complete kit which contains all prefabricated balsa and plywood parts, a nylon tank, two main wheels and a tailwheel, a glass-fibre reinforced nylon engine mount, etc..."

Quote: "Hi Steve, FlyBoy from Svenson. A real 'sports aerobatics' plane. 59in span, designed by Leon Janssens. For .35 to .60 engines."

Hi Steve, in 2013 I sent you this plan and now my scratch-build Fly-Boy is finally ready for its maiden flight [see more pics 006, 007]. I’ve converted it to electro with following set-up: 4S 4000 mAh lipo, SK3 4240-740 kV motor, 55 A ESC, 12x8 APC eprop. Pictures from the building process can be found here: https://plus.google.com/u/0/photos/1064147... A small build report (in Dutch) can be found here: http://www.modelbouwforum.nl/forums/bouwversla... Keep up the good work, OZ is gold!

These and the 42" Mini-Boy are amazing to fly. Relaxing low wing trainer, precise but forgiving.

Hi, here some pictures of new builded Svenson Fly-Boy [main pic, 010-012]. Color scheme is from Svenson Katalog 1973-74. Best regards,

Photo 004 is my FLY-BOY, A Fly-Boy must be equipped with a 6.5 cc 2T. Only then will you fly like an original in the 1970s. The smell and sound of the engine are an experience on its own. A design by Leon Janssens, the CEO of Svenson, in the late 1960s. I'm sorry, an original FLY-BOY with electric motor. I have about 50 models from the 1970s, all with original engines, and also a few Svenson models with electric motor, but models that I have with original motor as well. Regards,

Hi Mary; Here's another picture of my Svenson Fly Boy, equipped with a 6.5 cc 2T [pic 013]. One of the first building sets that Svenson released. Flies very well. Kind regards,

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.
