Obstacle Avoidance System (OAS for short) is a drone auxiliary tool we professionally developed. With the help of OAS, the drone can fly around obstacles autonomously, which is a very useful feature for novice players to protect the safety of the drone.
If you are a novice player and are still in the learning stage of drone control, we recommend that you choose the version with OAS, which can effectively reduce the incidence of drone accidents. Of course, we also sell OAS for certain models separately, and you can also return to purchase OAS at any time.
But there is no doubt that it is a more affordable choice to buy OAS when buying a drone.
