Hay Andy85,
You've got a great combo going, you and I are almost dead nuts on our power choices and I’ve been completely stoked with my 6s, but this last weekend I just received (2) 4s 4500mAH 30C bad boys and ran my truck on 8s today and it's stupid fast! I mean in the middle of the soccer field cant keep this thing pegged and stable kind of fast, I cant even think of the amount of damage and carnage you'll do to your truck if your not fully prepared for it or just plane don’t care what you brake??, 10 /12s is insane power and if you don’t have the proper drive train to handle it you wont have much of a drive train left. But hay it makes for great reading and sounds like a fun experiment so I say GO FOR IT!..
