@David Eisinger posted:... the coasting feature worked by the axle gear back driving the worm. this design is accomplished by have a worm that has a double thread. the helix angle of the worm is such that the axle gear can easily back drive (rotate) the worm. the performance of the engine was compromised by a very high gear ratio which made for jack rabbit starts and poor slow speed operation ...
Interesting. I recall reading that an associated factor for the coasting feature was the use of non-cogging motors if DC powered.
