Years of RC experience has taught me that when it comes to props, less pitch means less speed, and more thrust (and vica versa)
When electrics came around things changed a bit, because BL motors can produce all the torque at almost any rpm.
Now with mutlicopters, we all started out with really flat pitch, SF props, the 10x4.5's being a firm favourite.
I am now playing with y-6's and the whole prop thing has me befuddled, and im hoping someone with some propeller theory can enlighten me.
We flew a large 900mm Y6 with both flat pitch , and normal sport e-props, and from all indications 14x8 props in this case, which is a relatively high pitch prop in my book, seems to perform much better.
The 2 questions I have :
1. why is this?
2. what is the theory behind the bigger and smaller prop on each arm of the y-copter?
Looking forward to your answers!
