Right now I'm only running my 3S 2200mAh with my TC3 Truggy with the HW 120A controller and Novak HV4.5 motor. I get close to 20 minutes of insane run and braking action. I get constant 10 minutes plus on the 2 Kong Power 3S 2200mAh in my MBX5T. So for only 6 minutes the single 30C 6S 2200mAh pack will do. The balance will be some what perfect as your motor will weigh about the same. The pack is small enough to give you options to move things around. I have attached a picture of an initial set up in my Ofna. Here you can see another arrangement:
