DSMX Range issue?

Many DSM receivers have what is known as "fly-by" telemetry, this is a very short range telemetry system intended to give telemetry data only at close range. The problem presents its self most noticeably in small BNF models which may have as little as 30m of telemetry range. This issue does not however effect the range of the actual RF link and the telemetry warnings may lead some pilots to think they have a range issue with the model when in fact they do not. There is a setting in OpenTX that allows for these telemetry warnings to be disabled and the topic is covered on the Multi-module website.

Disable the telemetry warnings with the check box below.

Visit the DSM page of the Multi-module website to learn more.
