Editing Synchronization gear (section)

===== Electrical gears =====
Post First World War German fighters were fitted with electrical synchronizers.  In such a gear, a contact or set of contacts, either on the propeller shaft itself, or some other part of the drive train revolving at the same number of revolutions per minute, generates a series of electrical pulses, which are transmitted to a solenoid driven trigger motor at the gun.<ref name=Williams1.35/> Experiments with these were underway before the end of the war, and again the LVG company seems to have been involved: a British intelligence report from 25 June 1918 mentions an LVG two-seater fitted with such a gear that was brought down in the British lines.<ref name=Woodman7/> It is known that LVG built 40 C.IV two-seaters fitted with a Siemens electrical synchronizing system.

In addition, the Aviatik company received instructions to install 50 of their own electrical synchronization system on to DFW C.Vs (Av).
