Went out last night and put 6 packs through mine. I started out with how I initially built it. I glued up some AKA Enduros to the stock wheels.

I'm running a Fantom 7.5 540 right out of the package geared 93/18 with a Tekin RS Pro and anywhere from a 5000 35c to a 5300 60c pack (which was a tight fit). First run just for 5-6 minutes motor came off at 135, ESC @ 110 and battery ambient (72*F)

I moved the battery back all of the way and ran my next pack there. Though not bad it made the truck less responsive and jumped inconsistently. I ran this pack for about 10 minutes. Motor temp was 153, ESC 118 battery still at ambient.

Next run I moved the rear shock bottoms in on arm (I built them in the outer hole as this is where I usually run my other cars/trucks) the truck started to "dump over" on corner exit (This thing really needs sway bars!) So I pulled it back in and changed back to the outer hole and stood them up to the outer hole on the tower. This run yielded a better feel but it was now bouncing off of the tires in the choppy sections.

Another pit stop, changed battery, put the shocks back to middle hole on the tower and changed rear pistons to 1.3s. When back out and by this time people started to take notice when an expert E-Buggy driver couldn't pull away from me. (He could in the sections that I wasn't going to chance breakage on I was on the stand for about 15 minutes with a "mental patient grin" on my face. I finally pulled off and temped everything. Motor was 178, ESC was 130 and the battery @ 92. Absolutely fine for a hard 15 minute run.

The truck was a blast to drive. It's not yet perfect but time will allow for things to be dialed in.
