Hello, the electric hovercraft uses to much energy(it needs 6 MW, but the grid only fits 3 portable fusion reactors that only produce 2,25 MW in total), I would recommend you to either reduce it´s energy usage or make it compatible with Bob´s Vehicle Equipment
My thought behind it was so it couldn't just run forever on free power. My idea with the high energy consumption was to force users to put more batteries to store energy for travel and have to allow them to charge from time to time. That is also why I made the extra high capacity transformer store a little power (1 mk2 battery).
