Does anyone know or remember the ratio of the gearing from the pony motor to the main on a D47U? :confused: I have it somewhere but can't find it. I'm not sure I am smart enough to calculate it from the teeth on the gear train!! :)

Pony starting engine to main engine ratio for the D4 is 10.75 to 1.
