The Tamiya 54391 Tuned Motor is focused on delivering reliable, repeatable power for electric RC cars, making it a good match for club racing and spirited recreational driving. It aims to maintain usable output over extended runs.
Serviceability is a key part of the design. The motor accepts a replaceable standard brush and can be cleaned with commutator cleaning brushes, which helps preserve contact quality and prolong operational life.
Cooling is handled by a heatsink-style can and end bell design. The black finish looks neat while the integrated heatsink brush holders aid heat transfer, helping the motor stay stable during longer sessions.
Designed for 6.6-7.2V operation, the motor reaches around 19,400 RPM at 7.2V and delivers 49 mN.m of torque at that voltage. These specs provide a sensible mix of acceleration and drivability.
For those wanting a tuned motor that is easy to work on and performs predictably, the Tamiya 54391 is a sound selection for many electric RC applications.
