Thanks for your help guys....I'll just unplug it after work tomorrow. do I need to worry about a memory on these batteries, or was that a problem with the old Nicad batteries. I seem to remember that when I purchased my first camcorder years ago,I had to charge then drain completely, and charge again to "set" a memory. Thanks for the advice on the voltometer....I have built 2 other planes, and all of them have them on board, their the lightweight ones that plug into your reciever, and give a constant lcd readout..I agree, great insurance considering the consequense.

Thanks again,

Len
