Bought some replacement blades for a friend's Walkera 22e (imho a pretty crappy helicopter).
They cost only $8.60 and I expected them to be pretty awful. After they arrived (which took a few weeks, mailed from Hong Kong) I tried them out on my BCPP. They worked very well, no balancing required and produced a stable hover and FF.
They are longer and less wide than standard blades but seem to work fine with my brushless setup. I had one minor crash so far and they seemed to hold up OK.
I ordered a couple of pairs and will use them for practice, etc. At this price I don't feel so bad about messing them up.
