High-Current BEC
10A continuous and 20A peak straight from the battery — enough headroom for heavy servo loads.
Power & Servo
PowerRail 14S
SKU · AAD-POWERRAIL-14S · Servo Rail with BEC
A servo distribution rail with a high-current BEC and protected outputs. Carries up to 12 PWM signals straight from a 4–14S battery and can switch into an ESC-telemetry mode on outputs 1–4.
Key Advantage
Up to 12 PWM channels with a high-current BEC straight from 4–14S — plus an ESC-telemetry mode on outputs 1–4 when used with H7-Basic.
Highlights
