NORTHROP P-61C BLACK WIDOW
« on: March 18, 2020, 02:10:41 PM »
This laser cut kit is a Profile Scale P-61C Black Widow night fighter for twin .19 to .25 engines. The airplane is 1/12th scale. The wingspan is 66” with a 663 square inch wing area. The P 61C model had 1600 HP more than the A and B models and was 60 MPH faster.  Do not use a pair of .15 or weak .19 engines on this airplane. The full scale airplane had a pair of 2800 HP rated turbo supercharged R2800 engines. The airplanes carried quad 50 caliber machine guns in the top turret and quad 20 mm cannons in the lower fuselage. The line guide is removable, it bolts to the inboard nacelle. The flying lines attach to the Bellcrank using round buttons like a racing airplane. The airplane does not have any leadouts or lines attached for static judging. The CAD plans show all parts full size. The kit contains all the control system parts for the removable lines including the carbon fiber 4” Bellcrank, the torque resistant Bellcrank mounting system, the carbon fiber tubular pushrod with left hand and right hand threaded ends with DuBro heavy duty ball end pushrod ends. The kit buyers will get a .pdf file of the Squadron Signal book on the Northrop P-61 and a .jpg of the 3 view of the airplane. If you want to compete in Profile Scale with a twin you don’t see every day consider this kit. The kits sell for $300.00 plus shipping from zip code 60449. Yes, that is not cheap, but 1/4 of that is control system parts and plots of the plans (3 feet wide by 24 feet).
Sheet 1 has been updated to show how to build this airplane as a "B" model.

Mr Pat, is this 1/3rd scale in 3 foot wide sections?

-that's a joke...my hyperbole has been misunderstood in the past.

Jim,
LOL- I tend to have more plans than most.
1. Due to full size templates of all parts.
2. I do not think that overlapping views is the best practice for someone trying to figure out a design.
3. With 5 1/2' wingspan and over 50" length the airplane covers a lot of paper. there are 4 sheets of 36" X 72".
4. The airplane is 1/12 scale.
5. The nacelle sides and their skins are all different because the engine centerlines are set up to be spaced symetrically about the centerline of the airplane. With the dihedral of the wing center section the wing cutouts in all eight parts are at slightly different elevations from the engine centerlines.
