I have not been around the forums much because the 3 wheel project has been mostly on the shelf for a while. No time...
I have a motor now, the maple deck is laminated and rough shaped and I have started fabricating wheel and motor mounts. I would like to get this thing going by summer. So I need to figure out how I am going to power this.

Motor specs-
80mm 70kv sensored
85amp, 70v, 5kw
Gearing will be 4.25:1 from 16t to 68t (should be good for 50-55kph with plenty of torque) I also have a 12t motor and 47t wheel sprocket for more tuning options.
I would like to run 14 or 15s. 14s would allow for easier BEC and Anti-spark switch (Torqueboards/APS). The options seem to be more limited above 12s for sensored ESCs that would fit easily under a board. Bruno from APS recommended one of his ev controllers, but they appear to be fairly large. Something under 50mm thickness is the target.
The controllers I have looked at are the APS sensored 200 and 300 amp ESCs.
