Can I make an arduous pilot drone?
): Cut tail wing on helicopter
The torque is generated by the rotary wing lift.
The helicopter rotates in the opposite direction.
My technique is to install the wheel on the bottom of the tail-cut helicopter.
Anti-torque generated by wheel rotation makes the helicopter not rotate (acts as a tail wing)
The helicopter is stabilized by the gyro effect due to wheel rotation
When one of the wheels is installed in the drones, a torque is generated, and it rotates in the opposite direction.
Two wheels mounted on the drones will stabilize while canceling the torque
2, the existing drones and helicopters are stabilized by the sensor
There is no torque offset by sensor (lift torque offset)
New way to offset torque
The existing drones are commercialized but not commercialized
I think there is a reason for stabilization.
I can solve the stabilization problem
