The plot thickens even further. We just received a new pair of booms from FeiBao, but they don't fit the rest of the airframe [X(] Pix attached to show the issues. I'm lost from here.....I really don't know how to go about rectifying this. I've emailed these photos to FeiBao but received no reply yet. There are some obvious differences between the old and new booms. Most notably, the new ones have the rudders live-hinged, whereas the old ones were mechanical hinges. Ditto with the new horizontal stab and elevator. If I lay a new boom over an old one, the holes aren't in the same place either. It's not far out, but it's obviously out enough that they don't suit the wings/fuse we've got I suspect the Velox we've got is a very old version and had been sitting around for a long time before being sold.
