I would be running outdoors on a medium size track.
Also, those of you who have focused on running a light setup, what advantages or disadvantages have you observed? Is it worth my time trying to make a sub 7 lb buggy? Thanks in advance for any help with this, guys.
From what I am seeing, the 4300Kv ProHD motor are definitely harder on batteries and will require a 1/8 scale ESC (SCT410 but without body for testing, so in essence a light 1/8).
That said, it gives the closest feel to the 1/8 scale setup I have on my EB48. If you are wanting pure lightweight setup, I would suggest sticking around the weight of 2S 7200mah battery (300 grams?) which I think the 3300mah 4S packs do. And probably go with a 3S or 4S setup to get more efficiency out of the vehicle assuming you want the similar punch to a traditional 1/8 buggy setup.
Though, I an see using a 1/8 scale ESC with the 4300Kv ProHD motor geared properly and a high quality 2S lipo could give you the performance you want.

Are your bearings starting to get old by any chance? And did you notice the motor maxxing out on rpm's at all?
Where are you topping out down the longest straight with either motor configuration?
With these motors, I am thinking proper gearing is going to be key.
