The blades are excellent workmanship, well balanced and finished, on par with any carbon fiber performance blades. The incorporated lights are spectacular, to say the least.

However, there are problems with the specs.
Hole is 3mm (as found on HK-T500), this is ok.
But the blade grip thickness is only 6mm. The rest until 10mm (the size of the blade grips on the HK-T500) has to be filled with plastic washers.

I only spun the rotor a bit to check for tracking and the whole thing went out of balance. I was barely able to dismantle the blades because the screw was bent by the huge centrifugal force.

These blades should be redesigned to have grips the same size as the blade grips on the helli, or supply a metal T washer that is one piece.
