Had some time to make more progress. The board is done, just need to solder on a few connectors and then test this bad boy out and see if it actually works and spins a motor before I assemble it into it's case and mount it to a bike for real testing.
Bottom shot of the completed traces. I was able to just barely squeeze in two 1uF 250 VAC low ESR polypropylene caps at each end on the bottom side. Since I couldn't get them installed the middle I decided to use the left over 0.1uF caps and parallel two of them on the bottom to go along with the two on the top side. In all this board has 4uF of low ESR polypropylene caps to hopefully help absorb any spikes. It has 3,900uF of low ESR 160V aluminum electrolytic capacitors.

All connectors soldered in and run through strain reliefshttp://dynamic.opticalanarchy.com:8080/ ... -top05.jpg
Just about done, just need to add on the spades for the phases and figure out how to connect the power to it. Got the one phase wire installed with a spade, just need to change the color of the heat shrink so I know exactly what it is. Accidentally installed a red one... oops.
I'm hoping to test it out tomorrow, still need to do the regen mod to allow it to work on high voltage, but that will only take a few mins. Everything just barely fits in the case. That 6 gauge wire has some really thick insulating on it and just barely fits because of two electrolytic capacitors at the end.
