Model came with no antennas from the factory. No predrilled holes either (except the one on the bottom aft fuselage), so the antennas did not fall off, they simply were not installed at all. See photos. 

Pre-assembled airplane model made out of metal with a high level of detail, and produced in limited quantities, which makes it a highly collectible item likely to appreciate in value with time. 1:400 scale means that the airplane model is 400 times smaller than the real aircraft, so they are small airplane models that fit in your palm. Not suitable for children.
