HobbyStar V3 110A Brushless Sensorless ESC, Waterproof, Temperature Monitoring

If your 1/10 car or truck has outgrown the little RTR ESC it came with, the HobbyStar V3 110A gives you a much more serious 2-4S sensorless setup without wandering into premium-brand pricing. It is rated for 110A continuous current and 520A burst current, with an IP67 waterproof design, aluminum heat-sink case, replaceable cooling fan, and motor overheat protection.

The useful part is the headroom. This ESC is built around 3670-size or smaller sensorless motors, and the are separate motor KV limits for 2S, 3S, and 4S on-road versus off-road/buggy/monster setups. In plain English: it is a strong 1/10 bashing and builder ESC, but gearing and motor KV still matter. Physics remains annoyingly undefeated.

The built-in BEC is switchable between 6.0V, 7.4V, and 8.4V at 6A, so it can run standard receiver electronics or HV steering gear when the rest of the setup supports it. Programming support covers the normal surface ESC settings, including throttle range, low-voltage protection, start/punch behavior, and thermal protections.
