Usage Scenario

After a hard day of bashing at the local park, Tom noticed his HSP 94111 was making a grinding noise. He found the plastic pinion gear was stripped. He ordered this steel gear set, swapped out the damaged part with the 26T gear, and was back to running full speed laps in under 20 minutes. The steel gear held up perfectly against the rough terrain and high torque of his brushless motor.

Micro Comparison

While plastic gears are lightweight and cheap, they often strip under the high torque of brushless motors or aggressive driving. This steel metal gear set provides the strength and longevity needed for serious RC use, making it a more reliable investment for anyone who drives their car hard.
