Is that Rob taking parts?
And if you want to know a LOT more about that, including a photo of the rocker arm parts that failed, just get a copy of the book that my wife and I wrote on it for Osprey's X-Planes series! (We get no royalties when copies are sold, so you won't be putting money in our pockets.) We have MUCH more information now for what we think of as "The Big Book of XP-67" but the publishing industry isn't what it was 10 or even 5 years ago, and we don't have any potential publisher for it. Oh well. Actually I'll attach that rocker arm photo here...
The Dutch roll tendency was slight at worst, and was thought by the Army's Flight Research Section to likely be a "hunting" effect due to the engines being slightly out of synchronization with each other, rather than anything to do with the aerodynamics of the airframe. If testing had gone on a little longer, that would have been explored further.
"Bucking" at low speeds is a bit of an exaggeration (probably resulting from comments made by one of the 3 Army pilots who flew the airplane, Col W. F. Cooper, for a magazine article 30 YEARS after his only flight which lasted just 35 MINUTES) because what the 3 Army pilots who flew the plane in May 1944 said in their report was this: "...light buffeting starts around 140 MPH indicated and increases down to the stall. The stall itself is not violent; however, it is apparent that the wing is not completely stalled and that the tail is stalling out. The ailerons are effective at the stall and no tendency to spin was noted." This sounds like normal behavior for most aircraft, and certainly preferable to those that suddenly stall without warning.
Almost all of XP-67's flight time was done by MAC pilot Ed Elliott. His notes on the handling during the very first flight are interesting in this context: "...at the highest angle of attack on the landing approach, longitudinal oscillation was induced by slight pressure on the stick in an effort to stabilize the airplane in the desired angle of attack. The oscillation…was induced by the pilot and was of a very low frequency and amplitude and was not considered hazardous" except in extreme aft positions of center of gravity. And "throughout this condition... NO SIGNS OF BUFFETING [emphasis added] or directional instability were apparent."
My wife and I talked to the son of the MAC pilot who flew almost all of the XP-67's flights, and his exact words were "Dad always said he loved that airplane." I think Cooper's comments long after the fact have muddied the water significantly, which is a shame. Granted, the 3 Army pilots' conclusions were that the airplane had problems, but bucking at low speed didn't seem to be one of them.
Sorry to go on at such length about such a minor bit of wording, but XP-67 has absorbed most of my life over the past half-dozen years, and I'd like to share what I've learned when I can.
