The Tamiya 42154 is a solid upgrade for serious crawl setups, enhancing low-speed torque and throttle accuracy for tricky terrain.

Is this motor suited to wet or muddy conditions?

The motor itself is not guaranteed waterproof; use protective measures like sealed housings or covers if you plan to run in wet or muddy conditions to protect the connectors and bearings.

How does this motor affect run time?

Run time varies with battery choice, load and driving style. Its low KV tuning focuses on torque rather than peak efficiency, so choose a battery with good capacity for longer trail sessions.

Are upgrades available for higher torque or durability?

Aftermarket options like reinforced pinions, upgraded bearings or heat management solutions can improve durability and torque handling. Check compatibility before fitting upgrades.
