Definitely go with something 2.4Ghz. since going with my DX3, I will not go back to a regular crystal based radio system. I really liked the feel of the airtronics MX3, if they got a 2.4Ghz version, give it a look.
Main thing I would want to look into is the stock receiver size. you can get the spektrums with that really small SR3500 receiver, but those are expensive even used. the SR3000 isn't bad in size, but with some setups you need that capacitor to get it to work correctly. Not sure if you do with the Airtronics setup or futaba.
