RE: From Hitec Eclipse 7 to a Futaba 7CA
i love my eclipse and wouldn't change it for anything less than the 14MZ!!! but it really depends on what you fly. i love the spectra module and feel that it is the best thing since sliced bread. i use it with my polks hobby synthesized rx and am NEVER grounded. only problem is that i have a bunch of frequency tags. the eclipse has some shortcomings like it's difficult to use dual elevator servos and there isn't a graphical display of trims and expo but other than that... i love it. and the service has been excellent from them as well.
as for the question, you can use all the PPM equipment you have with the Futaba in PPM mode. No problem... but why?
