They have all the same features as other high end radios, but they feel cheaply made. Both can be plugged into the computer to configure and update, however no other radios need bug fixes
and Ive never seen the need to configure the radio with my computer vs in front of my car in the pits. Also, the Nomadio and Spektrum can talk to (read bind with) the Futaba FASST RX and Spektrum RXs. THat is a nice feature.....IF you have already made an investment into another manufacturers receivers. Personally, stick with the other high end radios such as the KO Propo Helios, Airtronics M11, or Futaba 3PKS. I have owned both the M11 and 3PKS, and Spektrum DX3, and the 3PKS is the most comfortable to me, but the build quality of the M11 is better.
