I've decided to get rid of my 75mhz system now that I finally have the money to upgrade. I'm going with Futaba ( I know nothing of spektrum) The radios I'm looking at are the 3PM-X FASST system and the 4PL FHSS system. Problem is I get no info about the FHSS system from the Futaba main site. So, I don't know if there are any significant pros or cons for each system I'd like to have that information about the FHSS system before I go any further. If anyone can help me with this I'd be very happy, Thanks!
