You can try a set of Carbon fiber blades. The plasti-blades flex too much, If you land a bit too hard you'll get a tail boom strike and break or shear off the tail. Carbon fiber blades dont flex that much and are much more forgiving than the wood blades if what you are having is minor scrapes and dings. Even a minor impact will wreck a set of wood blades and the luck I have is that when I put a brand new set on..within 30 sec to 1 min I will ding them a little bit then wont even come close to anything for days. Its like I not alowed to have perfect blades. You get a little more stable flight too with the carbon fiber blades.
