| COPY. Contd. -2- EH3/LGS.4.19. 1. All speedometer drive troubles disappear as the little electrical machine will be fitted directly on to the transmission. 2. The troubles in the flexible drive will disappear. 3. It would overcome the difficulties as regards fitting the flexible drive up on to the instrument board. From the experience we have had with the little speedometer as an engine rev. counter, we know that it is wonderfully accurate, that it is dead-beat, that it is very much nicer allround than any speedometer we have ever tried. We have the advantage that the biggest part of the machine is already designed and proved. EH. | ||
