After running the Caster buggy for a couple of packs today, I have taken into account the use of a single 4s pack in one tray is overkill, and decided that it is necesary to swap out to dual 2s packs.
I was flipping left and right today, granted I was running on grass but hey, I still think I would highly benefit from dual 2s's
The CG is just way too high
Thanks for who ever gave me that idea
