Rumpler C-5 (oz4133)
About this Plan
Rumpler C-5. Scale rubber model German WWI biplane. Discontinued kit. Guillow's kit no. 206.
Quote: "Steve, Here is another long-gone Guillow's model, a good squadron companion for the Albatross. I would strongly suggest enlarging the fin/rudder significantly to make a well behaved flying model, it just looks too skimpy. The stabilizer however looks like it might be adequate. I got this kit off of e-bay and decided to scan it up for y'all. Enjoy."

Quote: "Before starting construction of your model, study the plan and construction procedure carefully so that you will have a complete understanding of the step-by-step method of building this airplane. Guillow engineering has provided you with the most up-to-date method for building a real scale flying model but only careful attention to detail will insure the success of your efforts.
Most prize winning scale models are the result of patience and careful workmanship. You too can achieve success by following the example of champion model builders - by working SLOWLY and CAREFULLY at all times.
The frame photographs shown on this instruction sheet are actual pictures of the model you are about to build. The line drawings under each photo show the method of frame construction but are not actual illustrations of the model you are making. In other words, refer to the line drawings for construction procedure - refer to the photos for con-struction details of your model.
BUILDING THE FUSELAGE FRAME: MR. MODEL BUILDER: The construction details shown are those of the SE-5A. This is not the model you are building but the method of construction is exactly the same in most respects.
1. Gently press fuselage formers and keel parts from die-cut balsa sheets and line up for use.
2. Pin top and bottom keel parts to fuselage layout, cementing Al to A3 as illustrated.
3. Cement one each of former halves B in position as shown - be sure formers are at right angles to keel.
4. Cement side keel A4 into deep notches in formers B.
5. When dry, remove frame from plan. Cement duplicate halves of formers B in place against keel and formers.
6. Cement duplicate side keel A4 into position. Cement L part in place.
7. Cement the 1/16 sq side stringers in former notches. Refer to side view of plan as an aid to stringer location.
8. Add other 1/16 sq stringers, then cement remaining L parts in place. Lightly sandpaper completed fuselage to remove balsa fuzz and any ex-cess cement. Make and add stiff paper cockpit covering.
BUILDING THE WING FRAMES:
1. Gently press wing frame parts (ribs and trailing edges) from die-cut balsa sheets.
2. Pin to wing layout and cement respectively to each other all E parts of top wing.
3. Cement leading edge and spars in place.
4. Cement all ribs F into position between leading and trailing edge parts. Be sure ribs are at right angle to E parts.
5. Follow the same procedure in assembling the bottom wing—pin and cement parts G in place then add the wing ribs.
6. The wings of models with scale dihedral should be cracked at ribs shown on front view of wing plan. Raise wing tips to height shown and then cement cracked joints - leave in position until dry. Refer to special note on plan for increased dihedral as an aid to better lateral stability in flying.
7. When dry, remove wing frames from plan. Carve and sandpaper leading edges to shape and then gently round all other edges..."

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 (oz4133) 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/Rumpler_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.

User commentsIn regard to the Guillow's Rumpler C5 the man is correct. my model of the C5 built some forty years ago had a distinct dutch roll, cured by a clear plastic subfin.

Good to see that Outerzone has located the Rumpler plan. I have one of these as a micro rc conversion with 4ch control. Thought that the photo may make a good contribution along with the plan.

It's actually a decent flyer too and one of my favorite models. I enlarged the stab a tiny amount, by enlarging the front spar profile by about 4mm, but the real solution for flying was to mix the rudder with ailerons. The plane has an adverse yaw issue otherwise, and since I only have a single aileron servo I could not set aileron differential without changing the linkage geometry. The aileron servo is mounted in the radiator to boot, lol! This was an interesting build, as it was done before the Spectrum micro brushless board was available. I reprogrammed the brushed Spektrum board to drive a bl ESC and 5gm bl outrunner, where a diode was used to drop the BEC voltage to within limits of the linear servos. With the board mounted far forward, I managed to meet my goal of not needing any nose ballast, with the small outrunner and tiny lipo. There's a short video clip of it flying here: http://www.youtube.com/watch?v=qCGnimb-FrI

Hi, attached you will find some pictures of my Guillows Rumpler [pics 005-010]. Converted to r/c and with brushless motor for 2S Lipo. Controls: rudder, elevator, motor ctl., aileron trim tab (only r/h and only on ground adjustable). Greetings from Bavaria,

* 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.
