Details



Built for air racing and high-speed FPV wing setups, it’s aimed at demanding RC aircraft and helicopter projects.

The GT45A ESC supports 2–6S LiPo and lets you switch the BEC output between 5.8V and 8.2V via a solder bridge.

The GT45A FPV wing ESC should be installed with careful heat management and safe operating practices to reduce overheating risk.

The GT45A wing ESC includes an XT30U-M power lead, A/B/C motor outputs, and selectable 5.8V or 8.2V BEC output for simpler FPV wing wiring.
