Thanks for your time and advice,last night I call Tower and they told me that I should ship it back and include the shipping invoice with the box,only regular shipping;today I call again and the Costumer service manager told me that they'll send me by mail the return shipping label and also a new plane and I'll get it for Tuesday.I hope that nothing is wrong with it since when I checked the kit a little bit more I found out there were missing parts,and everything was loose inside the box,so I went to my LHS and look in another kit and everything was perfect and all the parts tied with Scotch tape.
