This is the absolutely most popular trainer for electrics around these parts and what I most recommend for new folks who wish to first start with electric. In this package which includes the Attack radio system if you purchase a buddy attack or find an instructor who will uses one then it has a tremendous advantage over most of the mainstream radio systems and that is the cordless buddy system.
Here locally we have gone to great lengths to use these systems on some Hitec and some Futaba and although most instructors do downplay the idea at first It has proven to be a substancial phychological advantage for the student .
