| longer bladesSlider, if you're happy with the stock woodies now, you will be ecstatic with some real blades on it. I did not find that putting the longer blades on mine took more engine power. In fact, as I stated earlier, when I first put the MS710's on, I had to reconfigure all my pitch curves because the head speed was sooo much higher. If you're going to invest in a good set of blades I say go for the big ones. They shouldn't be any different in price and will give you a better flying heli. More disc area will give you more responsiveness and control no matter what your flying style. They will definitely auto better, that I can say from experience. As far as FAI & 3D, I can't speak from experience, but I would have to say they would work equally well in either regime. I can tell you my bird was a lot faster with the longer blades. I don't think you'll see different sized blades used in FAI & 3D so much as different style blades. Again, I am not speaking from experience in this area, but I believe the 3D blades are more tuned for inverted flight, but as a consequence have a slight bit more drag than FAI type blades. FAI style are a slightly different airfoil which has less drag and may result in some more speed for large maneauvers, but won't fly quite as nice in inverted maneauvers. Maybe someone else can chime in and add to this topic. Anyway, bottomline, my recommendation is if you're gonna spend the money for some nice blades, go ahead and get the long ones. |
So far, I understand the bigger blades will result in a higher load on the engine. I am running an OS 61-LX with a brand new Hatori muffler and it is screaming. Also, from what I can remember is that a longer blade will retain more energy for better autos. That is about the extent of my knowledge. What I was wondering is what the advantages are between a set of 680s and 710s and everything in the middle. Are the longer blades more for 3D, FAI, or Autos?
