Cool Richard that makes a lot more sense now. I don,t think anyone is doing a 27Htz synth probably just not the market for it. With. only six channels on 27 and shared surface/air, makes 27 the poor stepchild even for the car guys. Most of them eventually go to the 75Htz. Hitec does make a Spectra synth module for 75 but apparently not 27. Sorry I could not be of more help.
