Ok this might be a stupid move or might not be. I just started this rc heli flying a few weeks ago now I have a few birds yes I'm hooked bad,,,,and today I thought I'd go buy the dx8 and man oh man I'm lost it has so much more thing's and programming stuff but the main thing I got it for was the screen I can't see up close and the dx6i wasn't cutting it,,and this thing I can see just right so I bought it....now do I put in the new ar8000 and telemetry or not? don't know much about the telemetry but going to read up on it...or just keep the old blade 450 3d stuff and if they just as good what's in the heli is ar6115e now so change it out or not?
