Spektrum DX9 adds multicopter/camera related voice output

December 18, 2013 2:17 | By | Add a Comment

The latest v1.02 firmware for Spektrum’s DX9 adds several bugfixes as well as something a lot of owners will appreciate: Extra voice events for multicopter flight as well as camera operation. Specifically, words like “self leveling”, “hover mode”, “stabilize mode”, “return to launch”, “circle mode”, “head tracker on/off”, “gimbal control on/off/locked” as well as “video start” and “video stop” should prove extremely useful to multicopter and FPV pilots. Also contained are the words “Waypoint 1” all the way up to 9 – a hint at a possible waypoint upgrade for the Blade QX350?


All in all, a nice christmas present from Spektrum, which you can download for free from their website after you register your transmitter serial number.
