Fokker EIII (oz13814)
About this Plan
Fokker EIII. Rubber scale model German WWI fighter monoplane. Scale is 1/24.
Quote: "Flying Scale Fokker E-III, by Joseph H Wherry.
THE author used medium weight balsa for all parts except the landing gear which is hardwood dowel. The model is designed as closely as possible with available data to the scale of 1/2 in to the foot. The only part not to scale is of course the propeller, which however is realistic and close to scale. Built very lightly, the author's model weighs only 1/2 oz.
The fuselage is constructed first, the two flat sides (shown in solid black) being laid out directly over the side view. Study your plans carefully and note the solid 1/16 balsa side section at front of fuselage; also note gussets at the junction point of wing, and the small gusset at tail of fuselage to provide solid juncture point for the elevators. All longerons, uprights and diagonals are of 1/16 sq balsa. Join the fuselage sides first at front and back, then add all remaining crossbraces which are also of 1/16 sq stock.
The fuselage of the real E-III was square except for the three formers at front and on top of fuselage. These formers, shown on Plate 1, are cut from 3/64 sheet stock and cemented in place as indicated. The stringers are 1/16 by 1/32 and are cemented in notches on formers. Now from a small block of balsa carve the two cowl fairing pieces to outline; note the dotted lines on side view of fuselage.
Construct the motor cowl next, cutting the two formers from 1/8 sheet stock. The front plate is clearly shown on the front cowl former pattern by dotted lines; it is cut from 1/16 sheet stock with a small hole as indicated for the nose plug. This front plate is cemented to the back of the front cowl former.
The cowl is formed by connecting the two formers by 1/16 sq stringers placed in notches, the stringers being only 7/16 long. This assembly is now covered with 1/64 sheet balsa. When dry, cowl may be sanded to crossection indicated in side and top views, and glued in place.
With cowl in place and cement dried, streamline the two side fairing pieces, using razor blade and sandpaper. (The author finds the small fingernail emory boards used by his wife very handy for such streamlining etc; they can be purchased in most dime stores.) With the cockpit outline of heavy bond paper and the tail skid in place, only the rear motor hook is necessary to complete fuselage. This latter part is a small 1/16 diameter hardwood dowel inserted through sides at point indicated just forward of elevator by small black dot on side view.
The tail surfaces are next on our production list. The rudder is simply cut from 1/32 sheet, and the elevators are built of 1/16 flat stock of widths indicated on Plate 1. Elevator should be built in one piece, so it is essential to complete left half by tracing right half and reverse the tracing. Elevator is flat without camber.
Wings are next. Note that two rib outlines are shown on wing plan. The author used the scale rib on his model with excellent results. However, the less experienced builder may prefer to use the non-scale rib with camber on top surface only. The latter rib has the added advantage of being deep enough to accommodate a 1/16 sq spar. The author's model with the scale rib has no spar and may be duplicated successfully if the builder is cautious and accurate in his work. In any event, the wings are constructed directly over the plans. The right wing plan may be duplicated by tracing and reversing.
Cross-sections of leading and trailing edges are each 1/4 in wide. The wing tips are of 1/16 flat stock. Tips are easily cambered to same curve as top of the rib by soaking in hot water and allowed to dry. The small circles on the third and fifth ribs are the points at which the wires attach to the wings..."

ScaleType: This (oz13814) 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 https://en.wikipedia.org/wiki/Fokker_E.III
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.

* 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.
