Avian 100-Amp Brushless Smart ESC 3-6S Version A (SPMXAE1100A)

The Avian 100-amp Brushless Smart ESC for 3-6S (Version A) is a high-performance electronic speed controller designed for RC airplanes. It regulates brushless motor power and provides real-time telemetry to a compatible transmitter via a single-wire link, so pilots can monitor current, voltage, temperature, and RPM in flight.

With a 32-bit ARM M4 processor, aluminum heat sink, and heat-dissipating design, this compact ESC stays cool under load and is ready to install right out of the box—no soldering required. It uses IC-series battery connectors (backwards compatible with EC connectors), offers an adjustable high-power BEC with dual connectors, and mounts securely with included tabs. Programming is flexible through multiple options—Smart ESC Programming Box, SmartLink USB Updating and Programmer app, and throttle-stick programming—plus firmware updates. It also provides multi-point protection (over-current, low-voltage cutoff, thermal, and failsafe) and one-wire telemetry to the transmitter, including battery data when paired with Spektrum Smart LiPo batteries.
