Focke Wulf 190-D9 (oz2971)
About this Plan
Focke Wulf 190-D9. Rubber scale free flight model by R. Preston Bruning.
Quote: "The FW190D9-known as 'Dora 9' in Luftwaffe service was designed by Kurt Tank for high altitude operation and as a stepping stone to the long-winged super extended fuselage TA-152 series of aircraft. The D-9 ended up instead as the most successful of the Focke-Wulf fighters.
Originally planned to provide protective cover for the twin-jet ME-262 jets on take-off and landings when they were most vulnerable. The pilots soon found they could outclimb and outdive the BMW 801 powered Focke-Wulfs and were convinced it could outperform the P-51D Mustang. The role of the D-9 soon changed. Compared to the 'A' series, the tail assembly was moved aft and nose was extended to accommodate the jumbo 213 in-line engine and annular radiator. Noticeable bumps appeared ahead of the canopy on the fuselage and on the wings near the root fillet, to make room for two 7.9mm MG 17 machine guns and two 20mm MG 151 cannons.
The proportions of the real aircraft when scaled down are close to ideal for rubber power. First, with the tail assembly set far back, the vertical stab area hardly had to be enlarged and the horizontal stab area was only slightly increased. The long nose requires little or no ballast for flying. You can pack a lot of rubber in that long fuse lage for a longer motor run. The full scale prototype had generous dihedral and the tall landing gear would be ideal for prop clearance.
Let's start with the fuselage. Every effort was made to locate the stringers and bulkheads along the lines of the real aircraft. The fuselage was built by cutting out the entire fuselage profile through..."

Supplementary file notes
Previous scan version.
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 (oz2971) 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/Focke-Wulf_Fw_190
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 commentsDear Admin, Just a small photo of my interpretation the great man's 190D [pic 006]. I think as in all the old timer designs the motor hook is too far back resulting in pitch instability from Cruise to glide. Yours Sincerely,

Mr. Reid, two things can prevent a large cg change when the rubber winds down. 1. braid the motor and 2. provide a stop for the prop hook so there is some tension in the motor preventing it from flopping around loosely.

Thanks for your suggestions. My motor length is only 2 times the hook. To peg length so was not sure I assume braiding puts more tension in the motor keeping it taut. D Reid

* 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.
