The work carried out with the Pterodactyl l showed sufficient promise to make the construction of a more sophisticated aircraft a viable proposition. The Pterodactyl lV was capable of carrying a crew of three in an enclosed cabin. Trials demonstrated a high level of control and manoeuvrability, coupled with good handling characteristics, it was also possible to vary the wing sweep in flight.
