A: Seal G2 is primarily a high-performance RC boat ESC — it features dual-channel water cooling, 32-bit 170MHz processing, and supports both SBEC and OPTO configurations up to 350A. It is designed for RC racing boats, sport boats, and light marine propulsion where the ESC is mounted in the boat hull with water cooling lines. Dolphin is an industrial-grade underwater thruster ESC — it is fully waterproof (IP67 on the 300A model), uses shielded signal cables for long-distance underwater runs, supports FOC (Field-Oriented Control) for smooth and efficient motor control, and is designed for direct immersion in underwater thruster housings for ROVs, AUVs, and e-surfboards.
A: ZTW offers three marine ESC lines: Shark G2 (20A–120A, entry-level to mid-range RC boat ESCs, waterproof, ideal for sport and racing boats), Seal G2 (70A–350A, including HV versions up to 12S, with dual-channel water cooling and 32-bit 170MHz processor, suited for high-performance racing boats and light industrial marine propulsion), and Dolphin (100A–300A, industrial-grade underwater thruster ESCs with IP67 full waterproofing, FOC options, and shielded signal cables, designed for ROVs, underwater robots, and e-surfboards).
A: Beast PRO G2 is the competition-grade sensored ESC line — featuring built-in Bluetooth, iOS/Android App programming, real-time data logging, BOOST/TURBO timing, and support for Modified, Stock, Drift, and Crawler racing modes. It covers 1:28 (30A), 1:10 (100A–160A), 1:8 (150A–260A), and 1:5 (300A 12S) scales. Beast RTR (SL) G2 is the value-oriented sensorless line — waterproof, pre-programmed for RTR vehicles, with LED program card tuning, covering 50A–150A for 1:10 and 1:8 scales. Choose Beast PRO for racing and performance tuning; choose Beast RTR for ready-to-run vehicles, bashing, and budget builds.
A: For 3D helicopters, the ZTW Skyhawk series is the recommended choice. Skyhawk ESCs feature a dedicated governor mode for constant head speed, soft start for smooth spool-up, adjustable 6V/7.4V/8.4V SBEC for high-voltage servos, and support for high-current setups up to 300A. The Skyhawk 125A and 155A are popular for 550–700 class helicopters, while the 160A HV and 300A HV suit 800 class and above. For pilots seeking premium components, the XD Fly H-Pro series offers upgraded MOSFETs, improved SBEC, and exclusive housing design.
The three airplane ESC series are positioned differently: Beatles G2 is the value line — compact, affordable, with 5V/6V adjustable BEC and transmitter/LCD card programming, best for sport-scale and beginner-to-intermediate pilots. Mantis G2 adds App-based programming, higher BEC current (up to 10A), and ultra-slim/nano form factors, suited for intermediate-to-advanced pilots who want more tuning flexibility. Skyhawk is the flagship — designed for 3D helicopters and high-performance aircraft, with governor mode, 6V/7.4V/8.4V high-voltage BEC, 170MHz 32-bit processor, and support for up to 300A and 14S.
A: For fixed-wing aircraft, ZTW offers three main airplane ESC series: Beatles G2 (entry-level, 20A–120A, 2-6S, ideal for sport and scale planes), Mantis G2 (mid-range, 6A–160A, 2-8S, with slim and nano form factors for tight installs), and Skyhawk (high-performance helicopter and 3D aircraft, 65A–300A, 5-14S, with governor mode and advanced 3D features). Choose based on your motor's current draw (add 20–30% headroom), battery cell count, and airframe size.
A: ZTW (Zone Top Way), officially Shenzhen ZTW Model Science & Technology Co., Ltd., is a Chinese manufacturer specializing in brushless Electronic Speed Controllers (ESCs) and power systems for RC aircraft, cars, boats, drones, and industrial applications. Founded in 2007, ZTW designs, develops, and produces ESCs in its own 2,500 m² facility in Bao'an, Shenzhen, serving customers in over 60 countries.
