thinking about an electric outback, have a few questions , is the 30# thrust big enough for an outback? the hatch on the front is way to small for any decent deep cycle battery , has anyone tryied to install a bigger hatch, if so which one? what size battery would be good for a 30# or a 55# thrust motor. i allready have it registered, it was amazingly easy in delaware and only cost 10 bucks a year.
