Exactly. I'd rather go out and buy a couple sets of blades for $15 a pop than risk making things worse for myself and/or my heli. At the least, if that weight flies out you'll end up spending a lot more than $15 in parts for repairs, and if it hits you...you probably won't be flying your helicopter again for a while.

For something you spent $220 on, I don't see why anybody would want to take the risk and screw it all up (and screw themselves up) by trying to fix something as crucial as a rotor blade. Just go out and get another set, it'll save you a lot of time and money in the long run.
