One of the main benefits of all affordable flight controllers and motors on the hobbyist market is that you can really try some crazy airplane designs. [amazingdiyprojects] Yes Experimental coaxial helicopter design, The goal is that it may be used in a manned version in the future. (Video link, embedded below.)
The aircraft uses a pair of coaxial counter-rotating motors with large propellers. There are several redundant control surfaces under the propellers. One of the theoretical advantages of this arrangement compared to more traditional quadcopter type designs is redundancy. Although the quadcopter will start to roll when a single motor fails, this design can still safely descend with only one motor.
It also does not rely on the main motor for yaw, pitch and roll control. In a multi-rotor aircraft, the motor needs to reserve a large amount of available motor power to immediately increase the torque for attitude control. This kind of aircraft can use all available thrust from the motor for lift because the control is provided by the control surface. There are five sets of redundant control surfaces under the propellers, each of which is connected to a separate flight controller.
Another advantage of this design is that it is effective for a given footprint, because one large propeller is always more effective than multiple small propellers.One of the goals [amazingdiyprojects] It is to install the full-size process on the transport container or trailer, and it can be transported without disassembly.
