Tamiya 70185 Submarine Motor Mini for Educational Experiments

The Tamiya 70185 Submarine Motor Mini is a useful component for workshops and hobby projects that explore underwater propulsion and mechanical principles. Its small size and clear design make it practical for repeated classroom investigation.

Visual Design and Speed Upgrade

Marked by a red outer case with a white fastener and white rudder, the Submarine Motor Mini is easy to identify during group sessions. An improved winding increases top speed by about 40 percent compared with earlier units, with a benchmark pace of about 1 meter per 3.2 seconds.

The unit is protected by O-ring seals for water resistance and supplied with a 35mm suction cap plus a 50mm auxiliary board to suit different mount types. A rear rudder gives basic steering for guided trials.
