There is a fail safe in some radio systems, not sure if that Futaba you are looking at has it, though. The DX7 has fail safe built in, plus it is 2.4 GHz and pretty much inteference free.

As far as the other stuff you are getting, what field equipment do you have? Glue.. CA, Epoxy (5 minute and 20 minute), and maybe some Elmers or other wood glue. Fuel tubing, if it doesn't come with it, fuel filter if you want one.
