                    _____________________________________________

This is a factory model of the de Havilland Dash 7 aircraft in 1/72 scale circa 1975.   The model was aquired from a de Havilland employee without a stand or any final decals.  The stand is home made with an oak plinth and Herpa 1/48 scale metal assembly.  

Please note I have shortened the black vertical post into the model with only about 1/2 inch showing since these pictures were taken.


De Havilland Canada DHC-7 C-GNBX-X 02

de Havilland Canada established itself as the world leader in developing the short take off and landing (STOL) aircraft used around the world in remote area’s.   In the 1970’s the Twin Otter or DHC-6 was already established as one of the staples for de Havilland but it only carried up to 16 passengers.    There was a demand for a larger 40 passenger STOL aircraft and de Havilland decided to meet the challenge with a four engine turboprop the DHC-7, which was nicknamed the Dash 7.   It was given approval for development and production in the early 1970’s and made it’s first flight on March 27, 1975.

Production took place from 1975 to 1984 with 100 aircraft produced during this period.     1n 1984 de Havilland decided to move forward with it’s next model, the two engine Dash 8,  so the production was halted on the Dash 7.    Four years later de Havilland did produce a small number of special mission purpose aircraft with an additional fourteen Dash 7’s built.    In all only 114 Dash 7’s were ever built.

The Dash 7 was an excellent airplane, capable of operations from 2000 ft runways with up to 54 passengers.    This was possible because the aircraft employed a considerably more complex flap system which ran the entire length of the high-mounted wing.      This wing, together with the four powerful Pratt & Whitney engines, provided extraordinary lift right down to very low speeds.  Upon landing when thrust reversal was selected on landing, the same layout decreased lift, thus increasing the effectiveness of the brakes resulting in impressive STOL performance.     The very low 900-1200 rpm four bladed oversized propellers made the Dash 7 very quiet exceeding all noise restriction requirements of the time.

The Dash 7, however had the misfortune of bad timing to debut during a period of economic challenges when few operators were purchasing new aircraft and were looking for ways to reduce operating costs.     de Havilland’s own Dash 8 with only two engines burning half the fuel and requiring half the maintenance quickly made the Dash 7 obsolete.
