Today, The FCUs finally arrived, once I took them out of the box, I plugged them into my computer to make sure that they worked well and it turns out that they did. both the FCUs worked perfectly first try and sensors on there, The MPU6500 and QMC5883P sensors worked perfectly with no issue what so ever. I also received the case and I am very excited to make the drones and then make them work together to form a drone swarm!
