| ( 2 ) ................ We did three laps of each test, six in all, timing four of them as against our usual ten laps. On the road we have not allowed the revs to exceed 4500. The Clutch pedal coming up to the board is due to speed and not torque. We can reproduce it by reving up the engine. The vibrations of the engine are felt through all the pedals. In the Body you hear more, than feel them, the [strikethrough] half and main period. Re the Propeller, you will have received our report upon this. We shall remove the damper when we again get going. --------- [Signature] G.{Mr Griffiths - Chief Accountant / Mr Gnapp} W. H.{Arthur M. Hanbury - Head Complaints} | ||
