Beautiful plan of a unusual airplane. Many thanks! But the name Raab RW3A is not entirely correct. The German designer Fritz Raab has nothing to do with this aircraft, the aircraft is a Rheinflug RW-3a, developed in 1955 by Hanno Fischer. The second prototype D-EKUM from 1957 still exists and is flown by Hanno Fischer (now 93 years old!) regularly.

This site has a brochure of this aircraft, was not an obvious find so you may want to post the link http://porscheaviation.com/index.php/82-homepage/119-rhein-flugzeugbau-rw-3. Very odd plane, that one. Apparently this plan was in the August 1968 Radio Models magazine (UK).

Many thanks, Detlef. Have added "Rheinflug RW-3a" to the plan description now, so hopefully that will help anyone doing a search for this design.

I found the plans for the subject page interesting and did a little more web searching. I thought other builders might find this link useful; it has the most comprehensive information and the best pictures http://www.linkfang.de/wiki/Rheinflug_RW-3

This plan looked horribly familiar even after fifty years. I actually made one and it sort of flew. The problem was weight, not only was the construction heavy but the model needed a lot of ballast to counteract the weight of the tail mounted Babe Bee. These days I would minimise the thick sheet base to the fuselage, get the radio gear right up to the nose and use tissue covering. I threw away the fuselage years ago but for some reason I kept the Solarfilm covered wings in my basement and here they are ! [more pics 003]

Having written the above I had a look at the internet references and it appears that the 'real' Raab had quite a modest wingspan. The model was 90" wingspan for a 27" fuselage length and frankly looked ridiculous. I wonder if something wasn't lost in translation and the dimension shown for a single wing wasn't in fact the full wingspan ! Anyway reducing it by a foot or so might be beneficial.

I asked Detlef if he knew why RCME magazine used the name Raab. His reply: "I can not explain why the wrong name was used. Maybe through the "R" in RW-3. Both designers, Fritz Raab and Hanno Fischer, designed the first glider respectively motor airplanes in Germany after the Second World War."

* 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.
