I would appreciate it if you share this by clicking here: http://on.fb.me/GyroCopter I apologize for the ads.

Gyroscopic precession. Acts on 90 degree of that of the applied force.  Force applied, and it takes affect at 90 degree to that of the applied force.  That’s why helicopter blades work at 90 degree out of phase.

Gyroscopic precession.

Precession is a change in the orientation of the rotational axis of a rotating body. It can be defined as a change in direction of the rotation axis in which the second Euler angle (nutation) is constant. In physics, there are two types of precession: torque-free and torque-induced. -wikipedia.

Torque-free precession (gyroscopic precession).

Torque-free precession occurs when the axis of rotation differs slightly from an axis about which the object can rotate stably: a maximum or minimum principal axis.

Torque-induced precession (gyroscopic precession) is the phenomenon in which the axis of a spinning object (e.g., a part of a gyroscope) “wobbles” when a torque is applied to it, which causes a distribution of force around the acted axis. The phenomenon is commonly seen in a spinning toy top, but all rotating objects can undergo precession.

The engineering of the helicopter rotor are very complex, the blades are manipulated to pitch mechanically and consistently by the controls of the pilot.

There several types of engines that give lift and power the aerial platforms that can house a camera, two of them use propellers.  i though it would be interesting to learn a bit about the laws of physics behind the mechanics.  Here are some common terms used to describe the action of the physics.
