In stock: ships within 2 business days.
Low stock: lead time confirmed upon order.
Delivery: 4–9 days after shipment.
AGFRC A81BHS is a programmable 4.8–8.4 V digital servo with 220° mechanical angle, brushless drive, and 0.075 sec/60° speed for demanding RC applications
➤ The AGFRC A81BHS is a high-torque, high-speed digital servo for position-control systems that require responsive and reliable motion. Operating from 4.8–8.4 V, it delivers up to 35 kg·cm of stall torque and reaches 0.075 sec/60° at 8.4 V. Its brushless motor, FET drive, programmable PWM control, 333 Hz refresh rate, and 2 μsec dead band support fast and precise servo operation.
➤ Built with high-strength steel gears, an aluminum case, metal bearings, and a 25T Φ5.92 mm spline, the AGFRC A81BHS provides a durable installation platform in a compact 40 × 20 × 37.5 mm body. Its 180° ±10° operating travel and 220° mechanical angle support integration into RC and compact mechatronic systems after confirming load, geometry, and power compatibility.
