Anyone else had issues with the quality of the alum main blade grips and alum tail rotor grips? Both on my 450XS are worthless. The tail rotor grips somehow cause a horrible vibration once the heli reach mid stick. The main blade grips are noticeable not straight when installed in the head. I can visually see one grip is pointing slightly down. This was straight out of the box and also after I went through it and checked everything. it makes the blades impossible to track.

I've ordered plastic pieces to see if it resolves the issues. Then I will be taking this up with Heli-Max for a fix. Just wanted to see if this is a isolated instance or more common?
