This new Radio from Spektrum interests me because mainly of its built in telemetry, so you can monitor in realtime the state of your lipo or rpm etc.
The things it monitors right now look a bit basic to me, but I would hope in time as this Tx can be upgraded by downloadable firmware that extra features will be added to that and as extra addons come out.
This looks a interesting bit of kit and I am sure all the other makes will be bringing out new Units themselves with telemetry.
About £300.00 over here in Uk.
