The EXI v2 frame is really strong and tight. I have two spares, and haven't had to use them for the past year. I've just had to change the main bearing when I crash.
The head and tail are great also. I've gotten to inverted flight with them.
I wish I was as good as the better pilots here, but I just crash the
out of my stuff when learning new things. I'm glad there is a US retailer to feed me parts. I wonder how people can never crash. I do learn new stuff with gusto though
