Hi, i am also trying to landing/takeoff using the masking bits but havent been successful. i am able to move the drone using /setpoint_raw/local topic (movement via both position and velocity works). but when i set the landing bit 0x2000 or takeoff bit, the drone stays at the same spot. here is my setpoint_raw msg for landing (the drones hovers at a fixed point). not sure what i am doing wrong.
