Serious range problem-->Here is the skinny now
Rod,
I am not trying to argue about it but I guess I missed those threads. There are a whole bunch of RC'ers out there flying with 5 cell packs and your case is the first I have heard about it. It is obviously not John's propblem as he is running the 4 cell packs. I will say that unregulated a 5 cell pack can be as hot as 7.2 volts servos jitter, and that may be a potential source of noise but just an increase in voltage I just can't see it. But that is just my opinion, and experience. Every jet I own has a 5 cell pack and my range has always been excellent, both with the JetCats, and my old RAM's.
