Rotorconcept,inc Patrick Le Will not back product Internet

I bought a min-Q flying helicopter at a palm springs air show. Got it home and followed the instructions to synchronize the unit and found one of the propellers was broken. I made contact with the owner that I had meet at the show after 3 attempts. And he said he would put one in the mail. After3 weeks still no part. I emailed him again, he said it was in the mail I waited 2 more weeks still no part. I then asked for my 189.00 dollars back now no contact at all. I will not purchase anything from this company and suggest no one should.
