Query: No instructions. Did not fit

This training kit dis not come with any instructions. We had to look up instructions on several other websites before figuring out how to assemble it. The holes in the balls are too small for the metal rods to go through. We had to figure out all this before we figured out that it did not fit the model if rc helicopter we had purchased at the same time here on Amazon. Disappointed.
