The XP-67 bomber destroyer contract was received in September 1941 for a twin piston-engine fighter with a design top speed of 405 mph and a combat range of 2,385 statute miles. One experimental airplane was flight-tested for the Army Air Forces.

This airplane had one other insurmountable problem: a poor choice of engines. The Continental IX-1430 engine delivered a lower power-to-weight ratio than either the contemporary Allison V-1710 or the Rolls-Royce Merlin. That was the main reason why the engine was never placed into mass production. McDonnell claimed that this plane would exceed 470 mph, while it actually barely exceeded 400. They might have completely re-designed the plane to take different engines, but by that time the Army Air Force nobody no longer really cared.
Its quite possible that all that blending contributed to overall drag.It certainly caused disturbed airflow over the tail surfaces to the extent that test pilots refused to spin it.Just looking at the 3 view is enough to tell you that its short of fin area.all that side area in front of the c /g and c /p needs a large emphenage. Design of the nacelles was a problem for the prototype mossie. As for stealth no. Same as the Horten concept, designers were seeking goals other than radar invisibility.
If anyone could direct me to a good, accurate source of information on this aircraft, including dimensions, cross-sections, etc, it would be much appreciated. I am trying to develop plans for an electric powered R /C model.
I agree with Speedy. There is no need for vulgarity on this site. Go to the porno sites for that!!! The XP-67 was in reality the first aircraft that employed Stealth Technology with its design. This plane is an important part of our Aviation History. I hope to do an R /C Model of this plan one day soon. Long Live Aviation!!!!
This aircraft had a unique exhaust-angling system designed to channel the exhaust at high speed, using it to increase thrust. The system did not work as planned, and the airframe was unstable to begin with...
