Nice setup. What does OG mean?

So you say that setup will keep up with the truggies, that's great. The current setup, I can get a better average lap time than half the truggy drivers on our track, and that's with a HIGH CoG setup as well.
I'm kinda seeing where this is going, the whole trying to lower the CG, where does it end? You know?! At some point, it's just a truggy really, and can run with the truggies.
What battery trays are those? Impakt RC? I am thinking of using 1.5 inch carbon fiber angle on each side.
I am just wondering if it's better to lay the packs down for lowest possible CoG, or to stand them on edge to keep them more center lined?
What packs are you using these days, btw? As you can see, I am using a pair of 3s, 4200, 35C G3 packs, love em, getting another pair soon.
