Switch on the TX, switch on the RX, move both sticks (this puts a load on the batteries because all your servos are moving at the same time - which, does not happen continuously while you are flying) if the voltage monitor stays in the green while you move the sticks, then the battery still has a good charge. (theoretically one could still fly if the indicators are in the mid range - when testing under load)! The problem with on-board monitors is that people do not use them correctly !!
Actually a good charger is just about foolproof, if you use it properly, because it loads the batteries to discharge (a given) them while cycling them and if you monitor the charge / discharge times / amps you will have a good indication of the state of the battery pack.
For the second time!!
NOTHING IS FOOLPROOF.
This forum is under the heading of beginners and typically beginners make mistakes. We ALL have done so. Automatic chargers are convenient not better than the chargers that comes with a standard radio. Beginners have been know to plug chargers into a receptacle that is controlled by a light switch which gets turned off when leaving a room. Beginners have been known to plug chargers in reverse polarity. Other mistakes have happened that result in the battery not being fully charged. Testing before flight is the safest proceed. If your happy with your on board gismo as it is made then go fly, I am not happy with it as advertised.
