GN/Gypsy Special

Designed for VSCC hill climb events the 'Gypsy Special' is based on a simple 1925 chain drive GN chassis and powered by a 1929 DeHavilland Gypsy Aero engine of 6.0 Litres as fitted to Tiger Moth Biplanes.

“Even without modest tuning these aero engines with over 350lbsft torque will easily destroy some of the most robust transmissions. Therefore I designed all my own parts for the drive train but still retaining a classic vintage feel. These included the split sprockets, engagement dogs, shafts, gears and the bearing housing arrangements to ensure performance and reliability.”

Brand – Working from Tom’s drawings we produced all of the split sprockets plus the axle with the keyways machined.
