I made a step towards professional applications of Bi-copter configuration. Currently design a big inspection *(15 – 18 inch propeller ) copter I wanted to get familiar with behavior with ARDUPILOT code. The micro frame is best for safe experiments. https://youtu.be/A_MrDXRqFqM
Soon I will send him on a autonomous mission when i will install GPS.
Total weight is 180g (up to 220g with bigger battery) the GPS I use for autonomous missions with ardupilot weights around 18 grams so i will need to add it and probably choose bigger propellers to fly with it.
