 In use, pilots found that forward vision was compromised to such an extent that few operators favoured the installation and when the Royal Canadian Air Force ordered the type, the specifications included a new cockpit position ahead of the wing and immediately behind the engine.The design featured a first-of-its-kind (for Canada) duralumin monocoque fuselage with a streamlined oval shape and strut-braced metal wing and tail surfaces.Wind-tunnel testing not only was used to model the fuselage shape but influenced the placement of the tailplane which was altered from its original T-tail position to a high-mounted tailplane intended to keep the tailplane out of the water spray on takeoff.
