Ask about a Futaba 9 CAP or newer ,or JR 10X ,might take abit to get the ground freq from Futaba but 8 ch ground recievers are available ,30 model memory and a ton of easy programing along with switch to chanel sellection and audible nuetral points that are great for ESCs stop point.
Dual thraughtles can be used on single stick radio by just useing the side variable channels.
And self sensing recievers will also work.
And when your tired of running your sub its easy to go fly a chopper or plane by just changing the freq. module.
You will find the computer radio far more flexable and easy to use on multiple models.
Ask if the ground freq. module from a cars Futaba radio will work? I believe they are the same that I use.
Just my experiances.
