I recently got a good deal on some RMS motors, a 38mm set and 54mm set. My friend shipped them to me, and I should have got them today. But, instead, he got them back... in a different box, from the Post Office, smelling like solvent. Included in the box was a note apologizing for the inconvenience. He is going to ask them why did they search it? Maybe their sensors detected trace elements of propellant? What do you guys think?
