Paul,
Very good points, and I agree completely. There are far too many people who don't read or heed instructions, but there is no way to protect that type from themselves.
The simplicity and price of the Celectra really appealed to me, because I have four ACE chargers left over from my glow flying days. I didn't really need another NiCad or Nimh charger.
I spent a few months at Palmdale and Edwards AFB, with the Boeing company on the B-1B program. Had good friends living in Palmdale, but lost track of them years ago.
