The Ten-Sixty-Six Conqueror was a relatively little-known English 10 cc racing engine dating from the late 1940's. It was manufactured by Ten-Sixty-Six Products of Worcester in England. The engine was offered as a kit of castings and materials as well as being manufactured in ready-to-run form. Its relative obscurity arises from the fact that it was mainly created for the then-popular sport of model tether car racing. finding relatively little application in the far more mainstream activity of aeromodelling.
Although by no means the equal of many other contemporary 10 cc racing engines of its day, the Conqueror was nontheless a very good clubman's engine for those who were constrained to participate on a limited budget. Present-day tests have proved it to be a very dependable runner.
