Guess that means never 
Chicago weather pretty much ended any further testing with this board a little early. Although I got enough ride time in to make an assessment.
First I’ll start with the board update. Complete board overhall- 12s4p p42a in a split eboosted enclosure, Stormcore 60D+, Reacher 6388s
I swapped out the stock motor plates with some thicker ones that I had cut from sendcutsend.
Right, so how does it ride? For comparison I have couple boards right now with a similar configuration.
-12s5p VTC5a Evo w/ 6374s straight cut Boardnamics GDs
-12s6p P42a Evo w/ 6384s w/ helical cut Boardnamics GDs
First thing I notice when taking off on this board is the smoothness this gear arrangement offers by comparision. Feels even smoother than when I first built this board.
I was expecting to get slightly more torque/acceralation out of it, but I won’t say it’s unsatisfactory (100 motor amps). Efficiency doesn’t seems to be too great like what @linny is reporting, tuned high with a 2:1 ratio. Had to go pretty high on the brakes too
Top speed is somewhere right above 40mph, still very stable and carvey enough. It’s a fun ride.
