Sorry, I did misunderstand what you were saying. I'm not sure what blades you are talking about, but if they are for a collective pitch heli, they are probably all symmetrical blades. The only difference is what they are made of. Carbon blades will cut the air a little better and they are stronger, wooden blades are cheaper which makes them great for learning, but they will do pretty much anything a carbon blade will do. If you are a beginner, you will probably never tell the difference in either set of blades.
my question is the e-flight blade has 3 different type of blades symmetrical carbon fiber and flat wood blades i need to know what the difference is and is the flat blade the easiest to learn on
I'm not sure what you mean by flat blades? Symmetrical blades are the same on the top as they are on the bottom. They do make a semi symmetrical blades, but they are more for scale helis.
is the flat blade the easiest to learn on
It doesn't matter what blades you use, it isn't going to make the heli fly any easier. The only thing that makes helis easier to fly is practice, practice, practice.
Hope this helps.
