Yes, I have 4 Hyperion 3.700mA VX, two 2S and two 3S.
I use it 2S +3S serial wired, total 5S. The discharge is 74A and work great.
The NiMHs are 8 cells side by side packs, two 4K (maxamps), two GP 3.300, and 4 Intellect 3.800ma (two of them matched).
I bought the motor mount and a beautiful transmision case already polished, but the case don't fits in the Lightning chassis :007:
