Look at KX-One, battery is mounted above the belt, not good either
True. But batteries wieghs way more than a belt or shaft.
Having a shaft and the diffs above the batts, will raise CG. But since the batts are way more heavy than a shaft and the diffs, it might still be an advantage.
One thing to wonder about
: Why have nobody made a shaft car with the batts in the middle and the shaft besides the battes? Something inspired by the JRX-S...
