This is the DEVO F12E - an upgrade version of the proven reliable Walkera DEVO 12S RC controller. The appearance is a completely new design, it's a bit bigger than before. The biggest difference is the 5" FPV Monitor, it has a 32-ch 5.8Ghz Video Receiver built-in, so you just turn on the DEVO F12E transmitter and you will get real time video feeds from your 5.8Ghz Video Transmitter right the way, no need to do any cabling or worry about battery, as the DEVO F12E is basically a combination of a 2.4Ghz 12-Channel RC Transmitter and a 5.8Ghz Video Monitor. * Proven to work with Boscam TS352 Video Transnmitter, you just need to select the correct channel on the DEVO F12E menu, no need to flip any switches.
