"A great number of trainee pilots had been killed learning to fly this machine, as its tricks took some learning, although they were really simple to overcome. Its main trouble was that owing to its very small wingspan, and its purposely unstable characteristics, coupled with the gyroscopic effect of a rotating engine and propeller, it flipped into a spin very easily at low speeds. Consequently, in landing and taking off, a tremendous number of fatal accidents occurred, and a general felling of dislike for the machine was prevalent. It really had people frightened."
