Something else I noticed about mine..... The transmitter batteries sometimes come out of thier holder. When I pull the battery door off, there they are. They are AA's. While I've never had it cause ME a problem, it raises some caution. I suppose when I set the Tx down too hard on it's back it happens. You might want to look at it. At least you'll know.

I suppose there's too much space between the battery and the battery door. Maybe I need to put a thin strip of cradboard in there or something.

P.S. It's a great flying little plane. The ACT isn't needed even if it works perfectly (which I doubt).
