palas son mejores que la que trae el kit del hk450. Pues las que trae son de plastico con un refuerzo en el interior, y aligeradas con unos anti esteticos huecos en la parte inferior. por lo cual recomiendo que te compres un par de estas para tenerlas
I ordered 3 of these thinking it would fit an esky belt cp, I was wrong. I also noted that one blade has a small damage near the hole. Now I need to buy a spacer and find a dremel tool just to make it fit the blade holder. I measure the grip using a ruler I dont have a caliper but the grip is like 4mm. Lesson learned, research more before you buy. But HC service is still one of the best.
My set arrived with glass/paint blistered completely along one side, I had to pay to return them and even then only refund of product cost given!! if I still wanted them I had to pay postage AGAIN!!!!(3 lots of postage, UH STEAL more money AGAIN!!!)

Well balanced, but the edges are finished unevenly. The end result is a lot of vibration when the roter is spooled up. Also, a lot of low frequency "thrumming" from the blades when spooled up. Haven't tried actually flying on them because I doubt the gyro will work with all the vibration.
not the prettiest blades (blemishes) hence the 4-stars. hole is 3 mm and thickness is compatible with 450 "clone" helicopters. I have ordered 4 sets, 2 each on different orders and all were reasonably balanced. Minor damage can usually be repaired with CA gel or epoxy. I like the heavier weight of these instead of wood as I am still a beginner and they seem to make the heli a little more stable. That said, they would probably be sluggish for 3-D flying.
