excellent for the priceligero y esta hecho con material de muy buena calidadBuild quality of the items I received appears very good.
Only a single grub screw not two as advertised. I will post agan when fitted and balanced.Great Quality with good price. Good Packaging.Know the motor shaft get the right adapterI purchased this adapter and came with a faulty spinner/nut.
The spinner/nut thread hole was off-center and causes a vibration when spinning at mid and high RPM, at the same time it cannot be tightened thoroughly as it is off center.
Funny how the support staff handled my concern and simply told me that, quote "I see the slight wobble I dont think this is a major problem." This guy obviously does not work on an RC of any kind.Better than my old collet type propadapter, Ill bever lose a prop again...very nice prop adapter has single hex grub screw to lock to shaft fits very tightly on 1/8 (3.175mm) shaft great!!I bought 6, all grab screw cannot tide firmly. useless.Prtico e bem balanceado
