| I have to put in my 2 cents in on this one. I have flown both on a small handfull of machines. Plastic, Glass filled nylon tail blades are just fine if... If you find a pair that are in balance. I had a terrible viberation and troubleshot it to out of balance tail blades. Who has ever thrown a set of tails on a balancer or gram scale?? Not me until then. The blades were 1.15 grams off. Yes, it was more than enough to viberate screws out in a hover within a couple minutes. My c/f horizontal fin was a blurr, I bet it was moving up and down 2 inches.. My point.. I proceeded to look at other sets of plastic tails I had. Robbe " the BAD ones", Thunder Tiger, Kyosho, etc. They seemed to vary quite a bit in weight. They were close, but nothing like the carbon blades. The 2 sets of carbon blades I had were more or less matched. As I mentioned, I still use both kinds. Just pay close attention to weight and balance. Misperfections may not be visible.
