ISDT ESC-90 — Waterproof Brushed ESC for RC Crawlers
The ISDT ESC-90 is a powerful and compact brushed electronic speed controller designed for RC crawlers and demanding 1/8 or 1/10 scale applications. With a continuous current rating of 90A, Bluetooth app programming and a waterproof design, the ESC-90 offers precise control and reliable performance for vehicles used in challenging terrain and outdoor conditions.
The built-in Bluetooth connection allows users to connect directly to the ESC from a mobile phone, without the need for extra programming accessories. Through the ISD GO app, users can adjust programmable parameters, check real-time data and perform OTA firmware updates. This makes setup and tuning faster, easier and more convenient.
Designed especially for RC crawlers, the ESC-90 offers precise throttle and brake adjustment. Users can fine-tune throttle and brake curves to match their driving style, terrain and vehicle setup. This gives better control over low-speed driving, climbing, descending and technical manoeuvres.
The ESC-90 is equipped with an advanced built-in BEC. The BEC output can be adjusted through the ISD GO app from 5V to 7.5V, with up to 3A continuous current. This makes the ESC suitable for different receiver and servo setups, including applications using high-voltage servos.
For safety and reliability, the ISDT ESC-90 includes multiple protection functions, such as low-voltage battery protection, over-temperature protection, throttle signal loss protection, BEC over-voltage protection and BEC under-voltage protection.
The waterproof design helps protect the ESC during wet and dirty driving conditions. After use in water, mud or dust, proper cleaning and maintenance are recommended to help avoid corrosion and ensure long-term reliability.
Compact, programmable and built for control, the ISDT ESC-90 is a strong choice for RC crawler users looking for a smart brushed ESC with modern app-based tuning.
