The props you listed on the RCtimer site I have used, sorry to say I could not get them to fly as smooth as I would like. One thing I do if I want to have a smooth flying Quad, Hexa ect... Is spend a little extra on the props. The ones I have used are GemFan, APC , Graupner and Carbon Fiber.
GemFan would be the cheapest props I would buy for a quad, APC comes in next. Then it is a toss up between the Graupner and the CF slow fly props I am trying. I don't have enough flight time on the CF ones to say they are better are worse than My Graupners.
As Tony said, I was using Graupners on my FPV quad and broke one. I didn't have a replacement so I had to use a set of GemFan props. I did get close to a min. less flight time. In a hover in the yard you may not see the difference. But when you start doing a lot of forward flight the flex you get from a cheap prop will be load up the motor and flight times will suffer. Along with pulling more amps. I dropped my amp load by 5 amps when I use Graupner props over a GemFan. You can do a simple test, grab the props by the ends and pick up on the quad,/ hexa and see it the prop bends a good bit. Your better props will not flex that much, and tend to hold there shape. That is why I like to use the Graupners and CF props no flex. mean smoother flights. The prop want deform in flight. But I understand if you are on a budget and the higher priced ones are out of reach. But also think about how much money you have in you rig and think do I want to trust hundreds of dollars to a cheap made prop that may break and cause it all to hit the ground.
I had this happen with a gemfan prop.
You can see the in flight vibration before it crashed.
This is the same motors and same quad with Graupner props.
You can see how straight they spin very little deflection
But in the end it all comes down to what works best for you...
