About this Plan

Renard R.31. Rubber scale model of the Belgian reconnaissance plane.

Quote: "How you can create a most realistic flying scale model of one of Belgium's formost observation planes. It is an excellent flier. Renard R-31, by Robert Harrison.

BELGIUM may be a small country but its planes rank among the world's best as far as performance is concerned. The Renard factory is a relatively new concern in the manufacture of high performance military aircraft, but even so the Renard R-31 and R-32 can hold their own with any similar military craft. The R-31 and the R-32 both have the same basic design but the R-31 has a Rolls Royce Kestral engine while the R-32 has a Gnome-Rhone Mistral Major power plant. We shall describe the construction of the R-31 since its long sleek nose cowling. lends itself very well to model building.

The real Renard R-31 is intended for high speed, long distance reconnaissance duties. It carries wireless and photo-graphic apparatus in addition to three machine-guns. The construction is en-tirely in metal with the exception of the covering. A maximum speed of 200 mph is claimed, while the climb to 19,700 ft. takes 14 min 34 sec. Main dimensions are; span 47 ft 3 in, length 30 ft 2 in, wing area 345 sq ft. Now let's get down to the actual building of this interesting foreign machine.

Wings: Both wing panels are laid out full size. Cover the plans with a sheet of wax paper and pin a piece of 3/16 x 3/16 strip balsa in place for a leading edge. Pin a strip of 1/8 x 1/16 balsa in place for the trailing edge. Trace the outline of the wing tip pieces on a sheet of balsa 1/16 thick and cut to shape with the edge of a broken razor blade. Cement these pieces in po-sition as shown on the plans.

While these are drying, you can be cutting the ribs from a sheet of 1/16 sheet balsa wood. There are four different size ribs shown on plate 2 besides the false rib. Cement these ribs in position and after these have dried a while, cement the top spar 1/8 x1/16 in the slots provided in the ribs. Lay the wings aside and go to the tail units. Incidentally you can join the two sections and give each wing tip 7/16 in dihedral and allow this to dry while you're working on the tail surfaces..."

    ScaleType: This (oz13976) 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.

Apologies for the confusion. This Renard plan has now replaced the previous plan in this slot, which it turns out was a duplicate of the Ercoupe plan at (oz13844). Many thanks to Pit for spotting this.

* 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.
