About this Plan

Freestyle. Radio control sport model. Wingspan 53 in, wing area 504 sq in, for .40 to .46 power.

Quote: "Freestyle. Kevin Holland introduces his SIAI-Marchetti lookalike for .40 size engines.

The concept of the Freestyle was that I was looking for a 40 size low wing model which could be passed off as a scale model of a full size aircraft. l started looking through a few Pilot mags and found the basis of the Freestyle, which was the Italian SIAI-Marchetti SF.260, the so-called aerial Ferrari by the famous designer Stelio Frati.

I began the basic drawing by laying the wing chord and tailplane at 0 degrees with a moment arm of about 24 in. The next thing I needed was a canopy; I used the one from the R/C Scale Aircraft Su 26 (40 size), and the u/c as well, as they are easily available from the Nexus Plans Service.

Freestyle looks good and if you've already built a few models, you'll find this one easy to make. The model will do most maneouvres, those of you who were at the Nexus Autumn Gala, Old Warden last year will have seen how well it flew. Go on, give Freestyle a go!

Fuselage. This is straightforward to build using 1/8 medium sheet balsa for the fuselage sides. Once cut to shape, add the 1/4 in square balsa where shown, then cut and fit the 1/8 balsa doubler.

Next step is the formers F2 & F3, which are cut from 1/4 in ply, with the rear one, F6 from 1/4 x 1/2 in med/hard balsa. Make sure all formers are cut square. Mark the positions of the formers on to the fuselage sides. Trim them to fit as needed to clear the 1/8 balsa doublers. If you are using a building jig, Fl can be left in one piece. Otherwise, do as I did; cut it and build the fuselage upside down over the plan.

You should now have a box shape from the rear former. Cut the triangular 3/8 in balsa at the bottom, using about six cuts approximately 1/2 in apart. These will allow you to draw the rear of the fuselage together. Now add all of the top formers. If you do not wish to build and plank the rear decking, you can make/buy one from foam and veneer - it's up to you. The front of the fuselage is shaped from laminations of 1/8 balsa sheet... "

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

* 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.
