Didn't see this thread until now, have been having issues with hitec telemetry since it was purchased 2 years ago. I've only tried it a few times but the readings don't work. Voice module doesn't sync with transmitter readings (Aurora 9). With a good signal - I either get atltitude 0 or altitude 6000, on the ground or flying. Airspeed is intermittent. All have been updated but to no avail. Temperature readout says 'too hot' at 75 degrees even though high warning is set to 200 degrees. It keeps saying low fuel even though that feature is disabled in the VM set up menu. VERY frustrating. I recently contacted Hitec, they said to send it in for evaluation.
