yes it does make a difference which way the prop faces. Looking at your background at the Carden I hope you understand the correct way to point the prop. every prop is air foiled and should be facing the correct way of the rotation. if you look at the side of every prop you will see the air foil just like a wing on a plane. it does not matter which way the motor faces just as long as the prop is in correct way of the rotation. I hope your not flying the larger planes thinking prop direction does not matter. i think you misunderstood my comment in the RCPowers video.
