Hi Xantos I don't really want to go over all the hassle I had with my spectrum again and I am keen to put those dark days behind me but I will point you to a thread I posted at the time.I loved the Tx at the time and its spec usability price etc are very good and Horizon UK has exalant customer servis but I question the consistency with its build quality which may explain why one works wile others do not, I sincerely hope yours is a good one. http://www.rcuniverse.com/forum/m_11...m.htm#11412015
