hello，Suppose we use two helicopters to reverse assemble, remove the tail rotor, and build a coaxial reverse rotor helicopter.We want to adopt the form of six servo and two DC brushless motors. The upper three servo and one DC brushless motor, the lower three servo and one DC brushless motor. The upper and the lower are both helicopter CCPM control forms. Similar to ECA UAV it 180, how to modify the blade130 mixer?
thank you!
