Hi! I have a quick question. I want to buy a new electric since my hummingbird V3 that has served me so well and for so long, is unfortunately pretty beat up. I was looking at combo packages like the new century heli swift helicopter, but how do I know that it will work with my radio? I have a 7 channel that I got with my hawk pro package, but I'm not sure how to tell if it is compatible with any of the combo packages online. Is that because I'm required to buy a receiver to go along with it? Thanks in advance,

Dan
