That's interesting about the blades, I got a 3 sets with my VTI pro, nylon and only one set is flat, the rest all bend and curve upwards, I thought this was how they should be, despite the surprise of my friend who said they should be flat. I have the flat set on now and will be flying tomorrow so we will see.....

I have been back and forth with RcToys so much recently I dare'nt ask them to replace the blades.

Take a look at my vibration problem example here:
