What's with radio gear compatibility/
Sorry Dugster;
Your information is not completely correct. Newer Highend radio's today have switching capabilities.
For instance My Airtronics Stylist can change modes with the input of whatever I configured the Aircraft for. Whether it was for a Futaba setup and receiver I'd change polarity which is available. Thus making it usable on any configuration.
As for Dougsters comment ref: Hitec servo's all of the new Airtronics radio's that have z connectors/ z-receivers are all capable of using Hitec servo's. The Older style Airtronic's servo's can be adapted to work as well in a FMA & Hitec equipment.
Basic and Advanced Programming, PPM/FM, PPM/FM-Invert, PCM1and PCM2 Modulation, This is even available on there mid-range RD-6000. (Notice the word Invert)
Compatability is becoming less an issue as time goes on.
Hope this helps
