@lemur that's about what I figured. The 30S version seems appealing for my current build interest. I do a lot of downhill riding. I started out on a long board bombing hills. Speed doesn't scare me and my ankles are in great control of a one wheel, even with a high psi.
I'm looking to build a setup that can handle a lot of braking power. Coming up to a corner at 30mph and not knowing if trust the board to stop or tail slide through the turn is a bit concerning.
I have a 20s2p 250r GT that I am looking to upgrade from. Even with that setup, I can't seem to get it to fully support the amount of control I need for the corners.
I'm looking to build out a custom controller box to fit an extra 20cells and possibly run the x12.
