Bill: The key point here is to make sure you check for and remove any binding in the linkage that could draw th system down. Careful examination of the linkage and the end points will help out and will surely help with the flight time on flying day. And, of course, how you fly too. A lot of overcorrection will quickly drain a battery pack as well.
I've never had a lock-out with my DX7 receivers and I bought mine way back when they first came out. I've used both 4.8 and 6 volt packs. I am using 1200 mah 6 volt packs pretty exclusively now, though.

Thanks, just curious, thought maybe Spektrum had issue a patch, recall or something. I plan on buying 6v for my giant 19. I like 6v. all my 40 sized planes I'm running 2200 NiMh 6.v. Some guys at the field are running lipos for their giant scales. But the PT 19 is not 3d, so I think I'll be fine with 1500 -2200 NiMh's.
