Quadcopter forward speed
Your tilt angle, AplhaP will be limited by the upward thrust needed to keep the quadcopter aloft. the amount of upward thrust produced is proportional to cos(AlphaP). … The quadcopter will accelerate until the drag equals 17.3N.
But of course, it's not that simple. …

How to choose the right propeller/motor combination for a quadcopter?
Just to add to user65's good answer.
Rapid rotation about a horizontal axis will come from a large difference between the thrust produced by opposite motors. The larger the difference, the greater th …

Questions about quadcopter and radio controller
As I understand it, the flight control board allows you to control your Quadcopter using a standard 5 or 6 channel RC receiver. So you don't need any other equipment. … You'll be able to steer the quadcopter using the controller, but won't be able to use GPS or anything clever without adding some more electronics. …

Yaw angle calculation for drone PID from two distance sensors
This sounds like pretty simple geometry.
The two ultrasonic sensors are reporting distances L1 and L2. The Yaw angle can then be calculated:
a = atan( (L1-L2) / W )
