sgean dubh

Since the introduction of the BCAR Section "S" for Small Light Aeroplanes in 1985 there have been no new 3 axis microlights of British manufacture or design even taken to the very rigourous test stage. It is my contention that the Authorities can't (or won't) cope with anything new, they need a production status aircraft with "history" before they will even consider looking at it.

My first attempt at my own design was a two seat all flying canard called the Iolaire. This met with nothing but blocking even after all the structural stress calculations had been checked and the load testing completed in line with B.C.A.R. Section "S" approved methodology (available from the CAA website). It has flown, and proved stable and easy to handle, both in the air and on the ground, however an approved flight test program cannot be conducted without a TEST CERTIFICATE.

When I began to think about the design for a single seat microlight I went back to my aeromodelling roots (when I designed and raced FAI models at International level) and thought about the increase in speed and rigidity the flying wing layout offered. So the idea for the Sgian Dubh (pronounced skee an doo) came from a team racer. The name SGIAN DUBH translates from Gaelic (ancient Scots) for BLACK KNIFE, i.e. the old Highlander's dagger hence the emblem on the nose.

Following on from this, the third of my projects evolved, another single seat microlight called the Quaich.
