features, including pre-programmed steering mixes, full switch assignability and a convenient back-lit display. Spektrum DSMR
technology is an exclusive, frequency-agile 2.4GHz protocol that provides surface RC vehicles and boats with superb range and re-
sponse. This is particularly true in environments where many other 2.4GHz transmitters are in use at the same time. Spektrum DSMR
transmitters are also backwards compatible with DSM
