These propellers are specifically designed for multirotor use and for use with "pancake" style multirotor 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.

very good quality productOverall they are good props. I bought 4 pair to use on a Hex in order to have an extra set on hand. Out of the first 6 I tested only 2 were out of balance out of the package. a small amount of tape was all that was needed and they worked great. Im using them on T-Motor MN3508-29 380kv motors running 6s. They have good punch and help cut allot of the yo-yo effect that happens when decending in your own prop wash.
For the price, they are great. Just pick up some extras as they dont tolerate even the smallest ground strike without chipping.Finitura in alcuni punti pessima, manca la resina e si vede il tessuto. Bilanciamento pessimo. Su 2 delle 4 ho dovuto aggiungere tanto peso. Ho deciso di non usarle. Qualit scarsa. Soldi sprecati.
Finishing in some places very bad, lacks the resin and you see the fabric. Balance bad. On 2 of the 4 I had to add so much weight. I decided not to use them. Poor quality. Money wastedGreat props, really quiet and pretty well balanced out of the box (not perfect mind). Running 4s on AX-4008Q gives loads of lift.
