Science of FPV

Currently Playing: How to choose the right props for your quadcopter: FPV Freestyle, Racing, and Long Range

In this video I take a deep dive on some of the principles that govern the performance of the props that we use on our quads. I look at the effect of diameter, disc loading, number of blades and angle of attack on prop efficiency and thrust. Finally we look at what props are most suitable for different applications. This video was reuploaded to include a better treatment of L/D ratio as it relates to efficiency. Thank you to the commenters who brought this to my attention.
