Love my Cinestar 8 - 1100mm...... because of the good engineering that went in to the design. At one point I wanted to opt for the sexier retract landing gear but eventually decided the 3 legged rotating landing gear was better for my needs......... less total AUW and less to go wrong as shown here......by others....
Not my Multirotor...... I came across this item on Youtube.... where someone tried to add retracts to his Octo.... He chose to use the BEC on one of his ESCs to run the retracts.........
