Thanks a lot for the info from all that had a part in this discussion.. I just got a DX7 nd was told by a couple of guys that I needed to up grade the 4.8 v batt it came with. My first response was why would they give you 4.8V with the flight pack and then have everyone suggest upgrade. I am convinced that for safety's sake, I need to upgrade.. Do I also have to change chargers ???

Happy so far with the DX7.. Lots of hits at our field, so most of us are changing right away that haven't already. AMA came out to check frequency interference but found nothing.. But it still happens. Couple guys that haven't changes over to Spectrum yet, refuse to fly there..
