RE: Nicads
Stick 40, many people have the misconception that charging with a wall wart charger is "trickle" charging. Wall warts are designed to charge at a C/10 rate which is called a "slow" or over night charge. I have a 900 mah NiMh battery which has been on trickle charge for 2 years. I charge it at a slow rate for 15 hours after flying and then leave it on trickle until the next flying session.
