I've been flying with the repaired shaft ever since with no hint of tbe.
At least one other peep has reported a cracked shaft right out of the package. I think it may happen when the holes are drilled too fast. It's worth checking out!
This is why I put a drop on my shaft for every new one I get. It has saved a lot of trouble. But, you ask, why are you replacing the shafts?? I have built several of these 120s from scratch parts!
