What Are The Best Brake Pads? Cheap vs Expensive Tested!
The rotors might have been original but no way the pads were. Pads are usually give and take. Better stopping ability yields shorter lifespan and more wear on rotors. Longer lifespan usually doesn't have the stopping 'bite'. Sometimes longer life pads can be rougher on rotors than cheapo pads too.

Why do we need stators in compressors or turbines?
The shapes and pressures are chosen to maximise this because the pressures / gas speed decreases along the turbine. Without the stators, the angle of gas flow would need to change from rotor to rotor. The gas would end up 'chasing' the subsequent blades and the leading edges would have to be angled more and more.

Rotor vs. Propeller | Rotary Wing Forum
When I look at the way a propeller is typically designed - utilizing variance in pitch and chord or thickness over its length to compensate for the different speeds from it's root to it's tip -I wonder why a typical rotor blade seems to be almost constant in it's chord dimension and angle of attack.

Of course the question was clearly asking about true contra-rotating rotors-- two rotor disks rotating in opposite directions on each rotor mast. This might have a few advantages-- like allowing the Chinook to tolerate an even greater fore-and-aft variation in CG-- but would obviously introduce a great deal more complexity.

Can a contra-rotating helicopter simply tilt its entire rotor …
Counter-rotating rotors on a helicopter would neutralize the reaction torque into the airframe. So yes for a very small helicopter, it should be possible to tilt the main rotor for cyclic control, without hydraulic power assist.

Why are three-bladed helicopters relatively rare?
In the case of 3 blade systems, rotor vibration and noise have multiples of 3/rev, 6/rev, 9/rev. 2 AND 4 bladed systems have multiples of 2/rev, 4,rev, 8/rev, 12/rev. Odd numbered systems rarely exhibit submultiples great enough to be of concern, while even numbered systems can cover the spectrum. Think 5 vs 6 blades.

20 I admit that this observation is entirely subjective, but it seems to me that there three-bladed rotors are significantly less popular than two or four. Factors that I'm guessing contribute - Storage - two-bladed helicopters take up a lot less space. So you're probably going to stick with two blades until you're compelled to move to four
