Multiplex M-LINK telemetry - first thoughts

Multiplex are making quite a splash these days. Their M-LINK 2.4 GHz spread spectrum system is bi-directional, and supports a neat system of fully integrated telemetry.

The DR and DR-PRO receivers have telemetry of receiver voltage and signal quality built-in. Telemetry data is displayed directly on the Royal Pro and Cockpit SX M-LINK transmitters (no external data viewer box is  necessary).  The telemetry-capable receivers can also link to external sensors for monitoring current, voltage, RPM (two types), temperature, and altitude/rate of climb.

I am currently testing out a telemetry capable M-LINK system for review in RCMW (March or April 2011 issue). First impressions are pretty positive, and I'm really looking forward to flight testing it. [As I write, the wind has dropped to around 10 mph, the sun is shining... it's time to go down to the field!]

All connected: RX-7-DR receiver and two external sensors. Even without any sensors, the Rx transmits Rx voltage and  signal quality. To give you some idea of scale, the batteries are AAA size.
