Hey guys, just an update with some photos. I ran the truck last night on 16 cells with 16/52 tooth combo and it pulled smooth and hard until the Quark started having a little heat issue.
Did not realise it at first when it started cutting out on acceleration and then applying the brake,

but after checking the temps... I decided to stop the run and allow it to cool off a bit...
When I re-started it, all seemed to be fine. I had assembled the ESC on the truck with out running a the heatsink that was there before, so it hod no way of cooling down... I will be fixing this tonight.
The current layout pending a heatsink and fan for the Quark:
Stay tuned
