Long Range Kit w/ encrypted telemetry link

Increase range by up to 20 miles with our long range package.

Product Overview

This system consists of a long range UHF RC transmitter module and receiver as well as two long range telemetry units (~900Mhz). Range is increased up to 20+ miles. Our long range kit has recently been upgraded to provide an encrypted telemetry link as well as a bidirectional RC link. This enables not only telemetry data to now be transmitted securely but also the ability to receive and transmit data and commands over the separate RC communication channel as a backup fail safe.
