        company designation maintained the family lineage. The
        choice of the unusual cockpit was predicated on the need
        to have a large front cargo compartment as well as
        considering the load distribution in normal operation. In
        use, pilots found that forward vision was compromised to
        such an extent that few operators favoured the
        installation and when the RCAF ordered the type, the
        specifications included a new cockpit position directly
        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.
