Definitely worth a try, I ordered 3 sets just to have them. My rigged ones do scare me a little. They seem solid but I'm still concerned they might break when the motor is at full speed. We basically had to double the size of the thread to get the rods in there so the plastic holding the threading has to be thinner and weaker.

Come to think about it, I don't think I'll try flying it until these come in. (Maybe a short hover or two while wearing goggles) I hate waiting but would hate trashing this bird due to mechanical failure.
