Since my skill level is intermediate, I'd rather not invest on those expensive fiberglass/carbon fiber blade. I am currrently using AEROTECH woody's. Is there another way to tell if the blade is warp aside from visual. Do you think I have covered all the areas that my cause the vibration? Well, I can't wait until the hobby shop open so I can get the part and put the heli together so I can test it. Thanks.
