Not bad, but needs one improvement

It is one thing away from being perfect, the motor shaft will bend after your first hit, but if the blade adapter included in this kit extended down to cover the top of the motor, it would drastically increase the dia of the area that absorbs the impact. Electronics are good, all in all it is worth getting.
