Albatros CIII (oz1162)
About this Plan
Albatros CIII. Free flight scale model, for .75 to 1 cc motors.
Update 15/01/2021: Added article, thanks to RFJ.
Quote: "EVOLVED FROM the Albatros BIII unarmed reconnaissance design, the Albatros CIII became the most widely built Albatros C type of the First World War.
Coming into service late in 1915 and continuing to serve on most of the war fronts until early 1917, undertaking throughout the period many different roles, from photographic to light bombing duties.
My interest with this type of aeroplane is a result of building an Albatros CI radio-control model some years ago for the BBC television series 'Wings.' The Atbatros has many attributes to make it a good free-flight model and as a result of its long service career various colour and camouflage schemes can be applied.
Tailplane and fin: Cut out the shape of the tailplane and fin front in. medium hard sheet. Draw onto one side of the sheet the positions for the ribs and spars and then, by poking a pin through the sheet, the positions for the spars and ribs can be matched on the other side. The main spars are made from 1/8 sq and the ribs from 1/8 x 1/16. The leading edge from 1/32 in sq and the trailing edges from 1/16 sq.
The leading and trailing edges are formed by nicking the inside of the strip with the thumbnail, nicking as required to form the radius required. The structure is first built up on one side of the 1/32 sheet core, I use PVA white glue for building up all structures, as this glue does not shrink and induce any twisting.
After building up one side of the tailplane and fin, the opposite sides can be built by the same method. When all the parts have been completed and set, they can be sanded smooth to an airfoil section. The elevators and rudder although separate from their respective tailplane and fin, are attached by small pieces of thin aluminium or tinplate, which act as stiff hinges.
Wings: Start to build the wings by making plywood or aluminium rib templates for both the top and bottom wings, with the spar holes and notches cut out. The majority of the ribs and all the riblets are cut from 1/32 medium grade balsa. The ribs are best made by the sandwich method, from rectangles of balsa slightly larger than the templates then pinned together between the templates and sanded to shape.
With all the ribs still sandwiched together, the leading edge notch and spar holes can be cut. The holes for the central spars are made by first, drilling through the ribs and then filing out. To make sure of a good fit, a spar can be pushed through the block. After shaping, the ribs can be cut to length. Riblets can be made by the same method, or by cutting each one out around a template.
In building up the wings, first pin down the trailing edge (which should have the rib slots already cut in) and pack up the front edge to suit the undercamber. The ribs are slid onto the spruce main spars as a block and then each rib is slid to its correct position before slotting into the trailing edge and pinning down. Next add the leading edge, riblets and tip sheeting.
When the wings have set remove from the building board and add the remaining bottom spar and the 1/16 sq strips to the top and bottom of the wing tips, forming by nicking as described for the tailplane.
The ailerons are constructed separate from the top wing but are best built along with the wing to obtain a close fit. A design feature with some German aircraft of this period was to have reflex ailerons, this model is no exception. Although there is quite a bit of work involved in building up the ailerons, the results are worthwhile. Cut out the ribs for the ailerons as shown on the plan and with the piece of trailing edge blocked up, build up the ailerons as you would the wings..."

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

ScaleType: This (oz1162) 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/Albatros_C.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.
Corrections? Use the correction form to tell us the new/better ScaleType link we should be using. Thanks.

* 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.
