So began the installation. It went well, the only thing I noticed was that the holes in the bottom of the motor mount weren't tapped deep enough. I had some shorter screws around so NBD.
I had to file out the bump-start hole to fit the wider plasitc spur.
It's looking pretty good now.
5.5mm bullet connectors were soldered onto the motor leads. I like shiny things!
Only two more pieces and the puzzle will be finished. Unfortunately, these pieces will cost almost $800.
This is a 22T pinion against the 51T spur. There is plenty of space to fit the 25T pinion I bought, too.
