It's a long story but I now have two 1:8 scale models of the Napier-Railton under construction. The original model is well on its way to completion ....

Napier-Railton Model 1

Pre-painting construction of the second model is also well advanced ....

Napier-Railton Model 2

The Build Story hasn't been updated for quite a long time, but there will be more to come ....



Between 1933 and 1935, John Cobb’s Napier-Railton race car set a number of lap records at the Brooklands race track in the UK. In doing so he established a one lap record of 143 mph. No one beat that record before the Brooklands track was closed during WWII. The car also broke many endurance speed records.

The car was powered by a Napier Lion aircraft engine. The engine was a twelve cylinder ‘W’ arrangement of three rows of four cylinders which, in its basic form developed over 450 HP. It was the most powerful engine of is day and was used in a number of racing designs, not just for cars, but  also for planes and boats.

Napier-Railton CAD Drawing 1:8 Scale

 A very high level of detail is included in the CAD drawings. The drawings are the platform for many 3D printed parts.

Napier Lion Aero Engine

The Napier Lion aero engine was the primary power source for the UK airforce from 1918 to the mid 1930s.  

Notably, versions of the Lion powered the Supermarine S.5 seaplane that won the Schneider Trophy in 1927 and, of course, powered the Napier-Railton race car.
