Hello - I have⁹ a lyz L900 quad and I'm trying to find out if there are any different propellers that will give me more speed or lift ? And trying to understand what the letters & number on the propellers mean because I went out to change one of my propellers and there are different numbers on the replacements they sent with the quad ? So I'm not sure what to do ? HELP .!
 
Normally it's props size then prop pitch so if they are 10-5.5 it's 10 inches and 5.5 pitch , bigger props give more lift (if the motors are powerful enough to spin them up to speed ), racing quad has high KV motors so spin very fast and have a lower pitch blades
KV is rpm per 1 volt of battery so say your motor is 1000 KV and battery is a 3 cell 11 volt it is 1000 x 11= 11000 rpm
