I recently bought my first Quadcopter, a P3Pro. I have visited the forum many times to learn as much as I can from the Experts - Thanks. I have several hours with the DJI flight simulator and am almost ready for the big Maiden Voyage. I realize there is much debate regarding the use of Prop Guards, however I have decided to go with them until I am confident to remove my Training Wheels. I want to use a quick release set and noticed two brands are recommended the most. My question is which to pick from, the Bestem which uses two screws or the Summitlink with 4 screws or any other brands and why you folks recommend them. Also wondering on using thread lock and what brand might be recommended to secure the screws? Thank You all for sharing your Wisdom with a newbie !
