I bought a bunch of the Quanum motors convinced by the ads that they would be great.
That will be the last time I buy more than a single sample of a new product from HK, and test that sample thoroughly before ordering any more.
I only awarded one crown because zero was not an option.
I have seen some pretty stupid things over the years, but this one ranks as among the lowest.
The prop adapter is 5 mm.
The motor shaft is 4 mm, and protrudes from the face of the motor a length equal to the thickness of the base of the prop adapter.
That would be OK, except that the clearance hole for the shaft protrusion is drilled-out to 5 mm for a brass liner with 5 mm OD and 4 mm ID.
The result is that the material left at the base of the prop adapter shaft is paper thin and the shaft breaks off when the nose nut is torqued even just a little bit.
The prop adapters are useless.
Even if a few held together when torqued very gently, I would not dare to fly anything with them for fear the prop would break off in flight.
I also have sets of 4108 motors of 475, 580 and 700 KV, and they are all the same.
In total, 19 motors with no usable prop adapters.
Disappointed, frustrated, angry....

motori di ottima qualita e ben costruiti dei veri mostri, un po poca potenza per le sue dimensioni ma questo giustificato dal fatto che a dei consumi molto bassi! consiglio di usarli a 6s con eliche grandi 14-15
