HI guys. thanks very much for all the quick answers. I=m gonna go through all of your tips and I tell you back. As andy has realized, all my versions <radian software, firmware and bootloader> are out of date, but I downloaded them thinking they where the latest version and they are not. I went here: http://www.freeflysystems.com/products/freefly-radian.php Then I founded this thread talking about the new updates on those http://forum.freeflysystems.com/index.php?threads/radian-firmware-1-03.450/ I will updated from these link. But I think it will be better to have them updated on the web site. Ill report later! Thanks again.
