Anyone having this problem, it seems to be occuring at an unsustainable rate..I have replaced these rotors on an almost weekly basis....I was flying last Thursday, landed and picked up my plane to put it back on a table and someone says did you notice that you're missing a blade on that motor. It must have come off while flying.
That evening I replaced the rotor and set it up til next time. Today, I took it out, got one god flight and on the second flight, hear a thunk come out of the plane. Landed right away and sure enough another blade was thrown. The blades are not scrapping or hitting the duct, as I checked after installing them. I also ran the motors at a slow speed to see if anything is touching or whatever. So I am at a loss as to why this is happening. Any thoughts!! Anyone !!
