Well, KM seams to know more about this than I do. I set mine up like the pre-production Vyper Scott Stoops flew at AEF Jan 2009. As I recall the recommended setup for the Vyper when it first came out was the Torque 2814/820 or Omega 130/870 with 4S and the Torque 2818/900 or Omega 103/1030 with 3S. Since I was replacing my Aspera with the Vyper I went 4S with a Torque 2814/820. I've since switched to an Omega 130 to save a few grams an move the CG back. Now it seems the tide has changed and 3S is preferred according to KM. Just remember with 3S you will need a 55 amp speed control and more current capable batteries. A 45 amp ESC, which is perfect for a 4S setup, will not be big enough.
