  • Supply: 6.0V

For drivers wanting crisp steering and robust waterproofing, the Sanwa ERB-871 is a reliable choice for both racedays and trail sessions.

How does the brushless motor affect runtime and heat?

Brushless motors run more efficiently than brushed types, so the ERB-871 tends to generate less heat under load and preserves battery life during extended driving.

Is the ERB-871 compatible with standard 6V systems?

Yes, it is optimised for 6.0V input and will integrate with typical receivers and BEC setups that supply that voltage.

What mounting considerations are there for low profile servos?

Measure your servo bay depth and horn clearance first; the ERB-871's slim height helps in tight bays but confirm horn travel and linkage geometry before final fitment.
