About this Plan

Saab Viggen. Profile chuck glider. From the 'For the Tenderfoot' series.

Quote: "All-balsa profile scale glider is catapult launched. Has a flashing climb and gentle glide. Viggen by Frank Scott.

Viggen: The three-forked thunder-bolt from the hammer of Thor. Viggen is also the amazing new fighter for the defense of Sweden.

Built by Svenska Aeroplan AB, better known to us as SAAB, the Viggen possesses Mach 2 performance yet will not rely on vulnerable airfields. It is as versatile as our own Phantom and will undertake attack, reconnaissance, and all weather intercept roles. All of this, yet it only needs a 1500-ft runway, or highway, for its operations.

Our model has the flashing climb of the original, yet is quite easily built with little expense.

Construction: Begin by covering your work table with a piece of Saran Warp so the glue won't stick where it shouldn't; glue the 1/16 sheet balsa wing pieces together flat as there is no dihedral or curved airfoil. While the wing dries, cut out the fuselage from a firm piece of 1/8 balsa. Round the edges with sandpaper and glue the 1/16 sheet balsa fin and sub fin in place.

The wing should be dry now; sand it smooth and round the edges with fine sandpaper. The canard stabilizer, or foreplane if you will, is cut from 1/16 sheet balsa and sanded. Cut it apart at the center and glue back together propping up each stabilizer tip 3/4 in for the necessary dihedral.

You will find that it is much easier to decorate the model at this point than after it is assembled; therefore mark out all desired control surface outlines and panel lines with fine pointed felt tipped marking pens or ballpoint pen. Well-stocked hobby shops may have Swedish decals, but if not, make your own insig-nia on plain white paper with colored ink or pen, then cut out and glue in place.

To assemble the model it is only necessary to slide the stabilizer and wing into their proper slots and glue very securely. Make sure the parts are carefully aligned before the glue dries. Bend the launching hook from a paper clip, shove the end into the wood of the fuselage, and glue very securely to complete the model. It is important to locate the hook as shown on the plan.

Flying. Now that you're ready to fly the Viggen, check to see that your model balances at the location shown on the plan. No ballast has been necessary on our Viggens, but if yours does not bal-ance correctly, add bits of clay to nose or tail as required.

Hand glide your model to check for proper flight, correct turning with bits of clay on the high wing and do not warp the surfaces for adjustments, as the higher speeds during launch can cause over control and subsequent sur-prises.

Prepare the hi-start launcher with a ten-ft length of 1/8 flat rubber tied at one end to a stick driven into the ground and with a 30- or 40-ft length of string at the other end. A paper clip may be tied at the remaining end of the string to complete the catapult.

Now it's launch time. Slip the paper clip over the hook in the model and draw the rubber taut. Face the Viggen into the wind and if you grasp the model by the upper rear corner of the fin it will automatically come to the proper angle for a smooth, high launch.

If the model tries to loop as it comes off the towing line, simply add more string to the towline until the model comes off in a flat glide. If the model stalls in the glide and flutters down without recovering, add a bit of weight, to the nose and possibly bend the trailing edge of the stabilizer down to pre-vent diving. Note that the action of the elevators on a canard model is opposite that of the conventional airplane.

Have fun with your Viggen, and with a bit of turn in the glide you should have no trouble flying in a field the size of the average school yard."

    ScaleType: This (oz7922) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.

    If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.

    ScaleType is formed from the last part of the Wikipedia page address, which here is
    Wikipedia page addresses may well change over time.
    For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.
    Corrections? Use the correction form to tell us the new/better ScaleType link we should be using. Thanks.

I STRONGLY recommend building this model! I knocked one up in 30mins for my 6yr old son to fly that morning as he is small for his age and can't really get enough pull back on a normal catapult setup. So I made the "high start" from 6ft of office rubber bands daisy chained together and about 25 feet of kite string. Man does this thing GO! It's a fantastic flyer and my son now can get decent flights with this setup. I will be building another one and putting more effort into the finish(models worth it). Raid the scrap box with your kids/grand kids and have some fun.

I had my eyes on this one since you posted it, and Tommy's comment made me spend 90 minutes making one [main pic, 003]. Test glides so far so good, once I find a good chunk of elastic for the catapult, it's off to the park!

This plan is not detected in a simple search for ‘Saab’. Perhaps the name could be changed from just ‘Viggen’ to ‘Saab Viggen’. I’ll be taking a little 1/16 and 1/8 balsa with me to England next month, to build and fly this model with my 5 year old grandson. He’ll love it!
Gems like this turn up on Outerzone...
Thanks to you and Mary!

* 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.
