Eclipse 7 Transmitter with Spectra
I have both the Prism and the Eclipse, both with the Spectra module and use it a lot. I often help others check out their airborne radio equipment and both the Prism and Eclipse allow me to check out all major brands with either positive or negative shift. To me, this is a big advantage. It also gives me ulimited choice in selecting flight packs as it will drive all of them.
