To say I am a newbie when it comes to electrics is a gross understatement, conversely I have been flying glow off and on for over 20 years.

Now that that is out of the way here is my question. I have a Royal B-17 kit that i started YEARS ago. so far only the wing is built but not sheeted. I do not have any desire to worry about keeping 4 glow engines running and want to put electric in. My question is not the usual what size engine but rather how to install 4 electric motors.

Can everything but the motors be put inside the fuselage?
What wires do I run in the wings?
Do i put batteries in the wings?
I want to build most of the plane without the engines so i want to prewire.

Thanks for the help
