Want the quality of Alien Whoop with F4 Betaflight? This is the board for you! Built by my pal Charlie Stevenson and Team Alien Whoop, this board and the Alien Whoop ZER0 are the only Tiny Whoop flight controllers out there that are NOT made with all the cheapest possible components to make the largest possible profit. You'll feel the difference in terms of power to your motors, accuracy in acro-mode flight, and consistency between individual units. This is the best in class flight controller running BetaFlight 3.4.
