Hello,
Does stiff props make that much different than more flexible props in terms of flight time and performance?
Also if props are close to each other is there some interferentie?

Hello, here is story from a beginner quadcopter building, in which he shares his experience of picking up parts and configuring systems. He says that two-blade props provide a better lift for his copter. Also, he says, they break when they hit surfaces and therefore provide safety for the motors and the frame. Please, read the prop section and see if it is the right thing for you.

Hello.
I made some tests with inexpensive 16 inches versus more expensive ones. It ended that @1500g thrust on a 380kv motor, lowcos was drawing 250W versus less than 200W for the nice shaped one.
I did not run the bad one to full throttle because of the noise, but have a look at data I obtained. I made several motors/props/Esc comparison with my homemade thrust stand, and data from real loiter fligths does match pretty well to power consumption on the static stand.

That is very interesting Manu !
Especially seeing how the curves diverge with increasing load.
The 20% difference in consumption for a 4 kg quad is quite an interesting gain.

Alasdair, this is a very interesting subject, I am sure a lot of people as well as myself will be very keen to see your data published on this forum.
To me it seems that props should be one of the most important component of anything flying, but apparently there is very little difference between a topnotch prop and a run of the mill prop.
Grateful if you would publish your results
