Flameback 45A ESC

The Flameback 45A is a single electronic speed controller made in India for FPV and multirotor builds, rated for 45 A continuous (50 A burst) on 3–6S LiPo.

Key features

• Runs on 3–6S LiPo (11.1–22.2 V) with full digital protocol support: PWM, Oneshot125, Oneshot42, Multishot and DSHOT150/300/600.
• Full-NMOS design with a dedicated MOSFET driver and Rubycon low-ESR capacitors for low-noise, efficient switching.
• IP56-rated against dust and splashes, with built-in overcurrent, under/over-voltage and thermal-shutdown protection.
• Rated operating range of -20°C to 125°C, with a peak ESC temperature tolerance of 140°C.
• Lightweight at 19.5 g in a compact 45 x 27.5 x 10.8 mm package.
