F89 Scorpion Model Plans

F-89 Model Plans

Just got the plans printed and we are now offering plans for the Brown-Dudeck F-89 EDF Model. This model is based on the F-89J, the last version of the F-89 in service. The model statistics are:
Wing Span 50” (excluding tip tanks)
56” with tip tanks
Wing Area 508 sq. in. (excluding Tip Tanks)
MAC 10.16”
Length 51.6 in.
Design A.U.W. 5 lbs
Wing Loading 0.16 lbs. / sq. ft.
Fan 65 to 70 mm EDF
Scale 12.43 based on wingspan

This is a stick balsa model and is not an easy one to build. The build log is posted under the forum Electric Ducted Fan Jet Talk on the thread “F89 mk I Scorpian”

The plans set includes 8 2 ft X 6 ft sheets, a separate Bill of Materials, and a set of AutoCad laser cut files in DXF format on disc for laser cutting of the parts The price is $100 postage paid to a USA address. Vacuum-formed parts will be made available later at a reasonable cost Send PM for method of payment.

The pictures are of Larry Dudeck’s model built from the plans, mine is still in work.

The drawings were done to the old Beech Aircraft standards, when they were paper or 2D CAD. All before they got all screwed up with 3D CAD.

For any interested, I have just completed mod drawings to make it an F-89C. One builder is building his as a "C" model, The changes are to the nose, radome and tip tanks (smaller).
