About this Plan
XB-47D / Boeing B-47D Stratojet. Scale experimental turboprop bomber for control line.
Quote: "For the scale builder, a unique and beautiful airplane. Authentic and a proven flier for engines of .15 displacement. Twin engines - let's go. Propjet B-47D, by Robert L Parks.
Between 1952 and 1954 three XB-47D's were built to test the Pratt and Whitney T-34 Turboprop installation. Having seen these airplanes in the early stages of modification, we decided to build a model. Since it was difficult to see the entire airplane, we had to guess as to what the inboard nacelles would look like. This explains the difference between the photographs and the drawings because at a later date the Boeing drawings were available. The outboard jets were retained as a safety factor in case of power failure in the inboard nacelles. Exact performance figures are not available. It has been stated that the low speed performance was improved and the cruise speed was slightly lowered.
After you have studied the plans carefully and read the instructions, start construction by cutting out the fuselage pieces. Pin the keel pieces to the plan and set up the bulkheads. After the cement is thoroughly dry, begin planking while the keel and frames are still on the board. Be sure to leave openings in the planking near the bell-crank and landing gear areas so that these units can be installed when the fuselage half is removed from the board.
After the right side bulkheads are cemented and dried, install the wing platform, bellcrank mount, bellcrank, and pushrod. Now partially plank the right side to keep the frames aligned and the fuselage rigid.
At this point, the landing gear units should be assembled. Clamp a piece of y8 sheet between the two landing gear legs, making sure that they are in the proper relation to each other. Then locate the spacer piece, wrap with soft wire, and solder..."

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

* 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.
