BetaFPV Air Brushless Flight Controller v1.1

Looking to turbocharge your ultralight 1S whoop drone? Meet the Air Brushless Flight Controller, the first of its kind to harness the mighty STM32G473CEU6 processor, bringing a whopping 55% boost in computing speed over the F411. This flight controller isn’t just faster—it’s a precision-engineered beast with the ICM42688P gyro for impeccable drone posture and movement. Whether you’re diving into complex freestyle maneuvers or racing through tight corners, this flight controller has you covered.

It comes in two versions: a 4IN1, weighing a mere 2.9g, and a 5IN1, tipping the scales at 3.6g. The 5IN1 version is also packed with a Serial ELRS 2.4G RX for even more functionality. And let’s not forget the built-in 25-400mW VTX, saving you space and weight while boosting convenience.

But it’s not just about specs; it’s about experience. This flight controller offers fingertip control, taking your drone flying to new heights of accuracy and responsiveness. Future-proof your flights with a controller that outpaces the competition.
