I have two 3s 5000 mah 50c
Also 2 smc 3s 9000 mah 60c only one would fit.
Just ordered the outcast today. Not sure if I want to start out with straight 6s
I started with 4s 5000mah 50c hardcase. Outcast wheelie's and backflips no problem due to SWB design. I only run 6s now for the most part, cuz I'm a speed junky. That said, by design you can only accelerate, turn.. etc so fast due to massive torque, big knobby tires, and generally tall ride height. You certainly can lose control easier on 6s if you aren't focused on what's around you and what you're doing. That's why I prefer 6s. I feel totally focused on what I'm doing more so on 6s then 4s. Both are fun cuz the truck is loads fun in it's own right. I'd just caution you about higher speeds. Very forgiving rig, but like anything, more speed can lead to more damage if you screw up or hit something you didn't see. You'll adjust to whatever you choose to run, just keep it fun!Good input thanks man!!
My suggestion - Run 4s first.
All 3 of my Arrma 1/8 cars - I like 4s better than 6s. 6s is just too uncontrollable, and I end up breaking stuff. Like the neighbors mailbox... LOL
