Does that head have a 4mm feathering shaft with thrust bearings? Wow 119 bucks thats a deal. I was thinking about pulling the trigger on the exi vertex 450. The one were the belt attaches to the main gear. How did you get it so cheap? Were they on sale? Or did you have a price code? Heli looks smooth. I want to get another heli because my BH 450 is alittle worse for wear. Are the blade grips tight on that bird when you grab the ends of the blades and move them up and down? (No slop)?
