(for challenge) The ns 54 is designed after the basics of delphinus' high speed boat design though with a few twists. capable of reaching 800mph+ this slick craft includes a partial hydrofoil aided by floats to keep the craft high and dry. yaw controls move the forward rudder while roll can be used to professionally keep it upright. the wide tail offers excellent stability at high speeds and even turning up to 380mph-.although slight turning is still stable at max speed which is best achieved with on screen controls. Enjoy! - Nick PS: you guys don't know how rigorously I tested this thing, also 20% throttle holds around 330mph... Perfect for turning ;)
