Helio SPRING AIO Flight Controller


This Flight Controller from Helio comes preloaded with ButterFlight, an awesome alternative to BetaFlight. This is the First Flight Controller to have two processors, F4 and F3 both on the same board, The first one runs the main flight controller firmware while the second is responsible for processing and filtering 32kHz gyro data to provide the purified 16kHz output for the main processor. Phenomenal!
