Prop Theory and Multicopters

Hi 'Droners!

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!

  • Hi Wessie,

    I am also playing with Y6's and I can confirm what you are saying. The more pitch the more power and the better the Copter flies and handles.

    Me too.
