3T6B Mini Remote-Controlled Submarine Model Kit

Model Overview

The 3T6B Mini RC Submarine is a compact RC submarine model designed for indoor hobby use. With a streamlined hull inspired by real vessels and a simulated military camouflage finish, it offers the look and basic behaviour of an underwater scale model while remaining portable and easy to operate. The product is aimed at hobbyists, collectors and younger enthusiasts aged 3 and up who enjoy remote controlled marine models.

Control & Operation

Equipped with a 6 channel 2.4 GHz remote control system, the submarine moves forward, backward, left and right and dives to a maximum depth of 70 cm. The 2.4 GHz frequency provides anti-interference performance, allowing multiple units to operate together without signal conflict. Intelligent water-sensing technology activates the craft automatically when submerged and stops the propellers as soon as it leaves the water for safer handling and lower power use.

Runtime & Charging

Charging is fast and convenient via USB, with a full charge in approximately 15 minutes and around 25 minutes of run time per charge. The handheld transmitter requires 4 AA batteries, which are not included. Because the model is designed for indoor pools or bathtubs, the shorter runtime and quick recharge cycle suit repeated short sessions.

Design & Practical Notes

The streamlined hull reduces water resistance for more authentic movement and the simulated military camouflage gives the model visual appeal for display or tabletop dioramas. Small air bubbles can collect inside after launch and may affect handling; if the submarine responds irregularly, gently shake it while it is in the water to release trapped bubbles. Keep the remote controller well away from water at all times.
