Molto buona plastica di qualità e ben rifinito. Bene stampato.
Vedi sotto per le selezioni di dimensione.
Looks nice, though the bladeholder is not strong enough for high power set ups. When testing, a 8*6 folding prop blade holder broke, causing the loss of one blade, unbalancing and due to this unbalance the motor was torn out of the plane. This was at 11.5 amps, 11.1 volts lipo. Meaning more than 100 watts.
(less power worked fine)
Propellor blades look very nice, though the biggest size prop blades are in a cheaper looking plastic.
Blades are exchangable with the graupner folding props, and have simular shape.
For this price a nice product
though not recommended for more than 80 watts of power. The blade holder is not strong enough, placing the blades in a graupner holder would be an option.
Hole size is 2 mm.
Overall, usable for less powerful drive systems.
It would be nice if UH could add a quality blade holder to its stock, for higher power solutions.
+A really nice product.
-Have to be drilled and threaded with stop-screws if not glued to the shaft.
I will order all sizes if they will come back in stock.
