A bit of feedback for 3DHS if they're reading this forum, its a bad idea to send out an Osiris with the shorter motor mounting bolts loose inside the fuselage, mine arrived in the UK everything was perfectly packaged, all of the parts were in plastic bags and taped up so I'm assuming that they did this where the Osiris was assembled, when I was unpacking it and took the fuselage out of the bag, 4 bolts were rattling around inside and one of the formers was broken near the back of the fuselage, no doubt caused by those bolts, the longer bolts were in the bag of bits, why these bolts were left in the fuselage I have no idea, but you may want to have a word with your supplier as its not nice to have something shipped across the pond to discover something like that.
I've repaired it, but it shouldn't really of turned up like that.
