WebA more general tailsitter configuration with twin rotors needs to be studied. The Surrey Martian tailsitter was an adaption version of QinetiQ’s terrestrial Eye-On, which was a “helicopter assembly” twin rotor design . For this tailsitter, twelve disparate critical subsystems were detailedly designed according to the mission architecture ... Web19 Dec 2024 · For a quadcopter (or roll on a tailsitter), if you put in a constant actuator value (a constant difference in motor thrust) then you get a constant rotational acceleration (ignoring wind resistance). The speed of rotation in roll would (in principle) keep going up forever. For the pitch axis of a non-vectored tailsitter this isn’t true. gibs rdc
