About this Plan

Box Fly 20 S - Radio control sport model.

Quote: "For many years the Box Fly 20 S had been manufactured by the Japanese company of OK Pilot. Because of its simplicity of design, ease of construction and forgiving flight characteriestics it became a very popular kit both sides of the Atlantic. It was this reason why Simprop decided to take up production of this kit again. The good flight characteristics of this model were kept and some details of the kit were improved considerably. Among the inprovements are: a reinforced horizontal stab, a two-piece engine mount (suitable for all engines) made of plastic and the possibility to install a moveable tail gear ...a thicker leading edge (easier to sand) as well as sub-ribs ...your Box Fly is a model for every-day flying..."

Quote: "Hi Steve, I send you a Box Fly 20 S from SIMPROP. Date on Plan is 1983. Size of that Plane is about 52 Inch. All other data in mm and grams on the plan. I have flown the model in 1991 with a 3.5 cc ENYA. I will rebuild it sometime with a brushless motor. That Plan includes Parts-List, Instructions and Pictures... With a friendly 'spar and rib fracture' (German model flyer greeting). ToniK"

Update 25/08/2015: Replaced this plan with a clearer copy at 400 dpi, thanks to ToniK.


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

Good day, I send you my pictures of my last plane built with plans from Outerzone, the Box Fly 20 S powered by Saito .40 [more pics 003, 004]. It is a beautiful plane and very easy to fly. I have enjoyed building and flying this nice plane.

* 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.
