Overview
The Castle Creations Nano 4Amp BEC (010-0177-00) is an ultra-compact, high-performance external Battery Eliminator Circuit designed to eliminate the need for a separate receiver pack. By drawing power directly from your main flight or motor batteries, the Nano BEC steps high voltage down to a stable supply suitable for receivers and servos.
Despite its tiny size and feather-light weight, the Nano BEC delivers 4A continuous and 6A peak current, making it a reliable choice for high-torque digital servos and power-hungry receiver setups - especially in builds where the ESC's internal BEC is underpowered or absent.
For racers, builders, and weight-conscious pilots/drivers who need a clean, dependable BEC solution, the Nano 4Amp BEC delivers serious power without the bulk.
