Marionville Models

The NEPTUNE SB-1 is the first underwater RC model from Thunder Tiger. Equipped with high technology operating equipment in the inner hull tub, covered by the bright yellow outer hull, the SB-1 will let you enjoy the otherwise hidden wonders of the underwater world.

Adopting a static diving system, operating the SB-1 is just like the real thing. The system is driven by a ballast tank with pump & motor unit. Start the pump to induct the water into the ballast tank. Control the amount of water in the ballast tank, the submarine can dive from the surface and stay underwater in static. Using the propulsion power unit and full elevator and rudder control, you can drive the submarine under water with ease.

Equipped with an auto detect protection system, if the system detects low battery power, low transmisson signal or leakage, then the roll pump will auto start to flood the water out of the ballast tank and make the SB-1 float back to the surface.

Install the optional digital camera and you can watch the amazing underwater scenes as well.
