Discover the Silent World

The NEPTUNE SB-1 submarine is the 1st underwater R/C model by Thunder Tiger. Equipped with high technology operating equipment in the inner hull tub, covered by the brilliantly yellow color outer hull, the NEPTUNE SB-1 will let you enjoy the otherwise hidden, underwater world.

Adopting a static diving system, operating the Neptune 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 graceful sailing underwater. Install a digital camera (optional) and you can watch the amazing underwater scenes.

 Equipped with a auto-detect protecting system, if the system detects low battery power, low transmission signal, leakage, then the roll pump will auto start to flood the water out of the ballast tank to make the submarine float back to the surface.



There are 2 versions of SB-1 Submarine, 5220-F is the super combo version. All the necessary operating equipment already be included in the box  and aslo fully assembly. Just open, then you can play this fantasy model immediatley.
