HobbyKing Hydrotek¶
The HobbyKing Hydrotek is a relatively fast electric powerboat with self-righting feature (one pontoon fills with water while the other does not). The rear motor rotates using a steering servo making it a good test of Rover’s vectored thrust feature.
The motor only spins forward and the boat drives best at speeds over 2m/s.
