I have the Futaba 4YF 4 channel radio, how long do I leave the radio and receiver batteries plugged into the wall before they are fully charged? How long do they last while fully charged?

Of the starting field box stuff, what all do I need to plug-in and charge ahead of time?

I have an OS .46AX, I have never broken it in, or turn it on. Will it work well literally starting it out of the box and be ready to fly if I have an expert tune it?
