Large Belt Drive
Initially intended for the discerning modeller who requires a powerful motor but space does not allow a conventional straight - through drive, the Belt Drive System is a 1:1 ratio unit that consists of two brass flat pulleys, one threaded to suit the prop-shaft, and the other to suit the motor, each fitted with a locking grubscrew and a belt that, in the unlikely event of it breaking, is easily obtailed from any local electrical shop, thus eliminating postage.
