I've got an orange and grey one on the way.
I was thinking of using:
Scorpion 3014-1040 swinging either an APC 12x6e or Vox 13X6.5 wood
CC ICE Lite 50
Rhino 3s 2150 30c
If this doesn't provide enough power I'll switch over to a Torque 2814/820 swinging a Vox 14x7 wood. I've got this combo on the Hokusei Yak55m EPP HV and the power, speed and duration on the above battery is great.
