Phantom III Gearbox. Further to E/HDY.{William Hardy}3/HP.24.3.37, we cannot find any reason on the design side why the gear change lever centralising spring should have given 4 to 5 1/2 lbs on 35-EX, as the spring as detailed should give 2.750 lbs. Will you kindly let us know whether a spring of less strength than 2.750 lbs is required, and if so what load is suggested. E/HDY.{William Hardy} Hdy{William Hardy} | ||
