Thanks Guys!

You were all right. I made too many mistakes. I need to be educated more about "battery" as well as radio setup.
The battery I use is 3 years old. I charge it the night before, but with only 6 hrs. I believe it is not fully charged, and I miss believe the field quick charger can fix that problem, which is a very very bad idea.
The radio is my 1st brand new 9cap PCM. I did not specific setup the fail safe and I am not even sure is it on or off for that function. It did looks a bit like lockout in the air....cause none of the stick movement wroks.. anyway. it is too late. I still can not locate where it crashed. The chance of retrieveing the rackage is very samll. There are too many "long grass" swamp and trees around the field. I am more planning on saving money for building another one. It is gonna take me another year or two. Sigh!
