The Quanum series of carbon fiber propellers have been specially designed for multi-rotors and are manufactured to very exacting standards. They are extremely light and strong and you can expect an increase in performance due to their ultra thin and stiff carbon construction.
These propellers are specifically designed for multirotors with "pancake" style motors.The design of these blades is such that the lift produced by these blades is as evenly spread as possible from hub to tip.
These are also T style propellers which have dual mountings which means you can either use the standard 4mm center hole (which can be reamered for larger shafts) or you can use a tightening cover with 12mm centers and M3 bolts.

Bought 2sets all 4props perfectly balanced,i need not do anything. Very good value for money. I've even used the wooden multistar props but those were out of Balance.
Very good product.Perfectly balanced, no need to change anything! Now after ~24 flight hours on my quad (with gimbal, SJ4000 and 10.000 mAh Lipo) still no issues or damage, even after the quad flipped ~ four times upside down during landing on grass.
ABSOLUTE RECOMMENDATION!!!!Really good propellers... light, strong and they good have a good balance
