" The interior of the AQUA features a sliding seat to accommodate pilots of different size and allow easier entry, and twin joysticks for simple control of the vehicle . The forward momentum is provided by a single main ducted propeller mounted at the rear. Pitch angle is controlled by two smaller ducts on either side. The yaw control is via a small rudder slung underneath the AQUA. " http://www.diseno-art.com/encyclopedia/vehicles/watercraft/sport_submersibles/AQUA_submersible.html Szybowski |
