To charge my Hyperion 4s, 35c packs, I use the Hyperion Duo 3 charger. Works flawless.

I do not recomend the Elite mount. It was a waste of $80. The m Blox screws were not tapped long enough for the screw that was supplied. I had to change the screws and they stripped. I used the second hole on the block and it stipped easy as well. All this in one month and I am not a novice driver. I contacted Elite and he said to just buy another block. I am not spending another $40 for a block that will strip out. I put the stock motor mount back on and not one problem. I agree with Shane (SEF) to set gear mesh with the whole mount and center diff, much better. My car is wisper quiet.

I run the Tekin Rx8 with the 1700kv motor on an inside clay track, West Coast RC Raceway.
