As expected from a high-end set, depending
on the programming options installed, the DS-
12 is not lacking in features and has a
comprehensive set of the flight modes, mixes
and logic switches expected on a high-end
transmitter. In addition, a couple of novel
features can also be accessed via the online
upgrades; there's the transmitter
accelerometer function, which can be used as
a control or switch, or the voice command,
where you can instruct the transmitter using
spoken commands. It's not quite Alexa, as you
have to teach it the commands.

FLIGHT TESTING
As well as checking out the various
programming features, I also did some flight

testing using five and ten channel receivers,
with the MUli 6S LiPo cell voltage and MVario2
sensors, taking the opportunity to check out a
couple of the more esoteric programming
features mentioned above in flight. My fi rst
tests were with a Multiplex Funman, as it's
always good to get the feel of a new transmitter
on a known model. This was set up as a fi xed
wing with dual ailerons and all the servo
movements were easily and quickly dialled in.

I used the five-channel receiver and MULi6s
sensor to monitor total flight pack and individual
cell voltages of the 3S LiPo, with an alarm if an
individual cell voltage dropped too low.
I also took the opportunity to check out the
voice command feature; here you teach the
DS-12 a voice command and this can then
either be used with a master voice command
or a switch. I used the spring-loaded push
switch to activate the voice command and set
Jeti's transmitter wizard allows LUA scripts to be downloaded to the DS-12 for accessing additional features.
up voice commands for total cell and
individual cell voltages. Using the inbuilt
microphone, or a mobile phone headset
plugged into the transmitter, you fi rst teach
the transmitter the command and then assign
it to the relevant parameter you want
announced, then in flight activate the switch
and say the voice command to hear the
relevant sensor reading.

sensor to check a three cell LiPo. Individual cell performance can be checked and
here we can see that cell two is performing better than the other cells.
Right: DS-12 is supplied with a basic set of software, which can be extended
either individually or as the packaged bundles shown.
