Cheap propeller. I had to drill out the hole and tap 4-40. A few flights and the prop was unbalanced (likely due to my inferior flying prowess and ground contact).
Don't put the final, pointy nose-cone on, nearly impossible to remove. Fly without if you ever plan to take the prop off in the future, since one nose-in landing will drive the nose cone on very tight.
For 1.76, you can't complain too much... as long as you have the tap and set-screws available.Fits strong and safe on 2.3mm shaft.
i am using it with speed 400 on 2s.
Recomended for planes (gliders) from 150 to 300 grams or up to 400g with stronger motor.Nice propeller. However, it does not come with a grub screw needed to attach the propeller to a motor shaft. The nose hub is about 3cm in diameter. There is some slack between the propeller and the hub.the center hole diameter is 2mm, so if u have 3 or more you should drill it little more6x3,5 steht darauf und hat 16cm Durchmesser, Spinner ca. 29mm Hoehe ca.27mm
Die Spitzenverkleidung laesst sich nach Montage nicht leich herunternehmen die Blaetter sind gut ausgeformt fuer mittlere Belastungen und Drehzahlen 10g leichtdangerous product, two of them "exploded" in the first run. The blades flow away, the middle part was broken... I addition, the prop is very unbalanced, what a pitySimply don't understand why they don't make the hole for the shaft retaining screws.
Propeller itself is very good indeed, but no everyone have a cnc for perfect holes.
My holes are not perfect and so my prop is useless because it spin very badly.
If they make the hole will buy again because of its quality.Esta bien para el precio que tieneNice prop for small gliders. Anyway it hasn't worked for me. I bought it to use it with the Bonsai, but It doesn't fold all the way in both sides, No good to use in Flying wings. For all pull-prop configs should do the trick.GRANDIOSA MINI ELICA MOLTO ADATTA AL MIO MINI SWIFT!! GRAZIEEE
