Remove caliper and pull rotor off the hub. Push new one on, replace caliper and pads.
you just pull out the old one and put in the new one
the blade is called rotor bladesThe rotor blades on top are called Main Rotor Blades, because they are the main source of lift for the helicopter. The smaller rotor blades on the tail are called Tail Rotor Blades.
All helicopters have a tail rotor to stabilise them.
The tendency for a helicopter to drift in the direction of tail rotor thrust is called "Tail Rotor Drift" of "Translating Tendency".
Remove caliper, pull rotor off hub, push new one on.
The tail rotor is moving "perpendicular" to the main rotor, not "opposite". The tail rotor creates thrust opposite to the thrust of the main rotor, to keep the fuselage from spinning. Most helicopters spin the main rotor counter-clockwise looking from above, which puts a clockwise rotation on the fuselage. You need a tail rotor pushing the tail counter-clockwise to keep the fuselage pointed in the direction the pilot chooses.
Depending on the make of the helicopter, some will rotate clockwise and others will rotate counter-clockwise. However, the main rotor and tail rotor will spin opposite of each other. If the tail rotor spins clockwise, the main rotor will spin counter-clockwise. The main rotor also spins for lift, the tail rotor for control.
It is a push and a pull. When you move your body towards the ground, it is a pull. A pull as in a pull to the ground. It is a push when you are moving away from the ground.
A push or a pull is a force
Main rotor and tail rotor. The main rotor is on top of the helicopter consisting of two or more blades, and the tail rotor is at the back of the helicopter, which also consists of two or more blades.
Tail rotor thrust is simple the sidewards force provided by the tail rotor. This is required to offset the gyroscopic motion created by the main rotor. When the main rotor spins it creates toque in the opposite direction. The result, without a tail rotor, would be the main body of the helicopter spinning around in the opposite direction uncontrollably. The tail rotor simply provide thrust in the opposite direction to this toque and thus allows the main body of the helicopter to remain stationary. The blades of both the main rotor and the tail rotor spin at the same revs. The pilot adjusts the pedals at his feet to change the amount of sidewards thrust thrust allowing him to control his lateral movement.
