Attention DX3S Owners
Thursday, June 18, 2009
New DX3S systems (SPM3140) are now compatible with DSM2 surface receivers and the Marine receiver (SPMMR3000), in addition to DSM surface receivers. The SPM3140 transmitter features the above logo on the back.
If you own an earlier DX3S system (SPM3130) and would like it upgraded with the new technology, please contact the Spektrum Service center who will upgrade it for a small fee. The upgrade costs $50 plus shipping and the turn around time is approximately 3-5 weeks
