I don't recall if my 3PK has a full system reset. However, I'm positive that there is a model reset that you can use on each one of the 10 model memories. I believe that the model options are in System menu 3.
No there is not a full system reset. Page 32 in the Futaba manual, Model Reset(MDL-RES) This will allow you to reset one model at a time and is simple to use. I suggest downloading a manual from Futaba first.
