Do you need to plan on exactly where everything will be laid out or do you just place them on after the pan is cut out? If so what method is used to attach everything to the belly pan.

BTW- great looking testbed, we did something similar this offseason and its going to make testing and prototyping so much easier/quicker

You need to decide how you are going to attach each of the electrical components to the pan; screws, zip ties, Velcro/DuoLock, etc. You would then decide where to place each component and where the wiring channels will go. It would be good idea to place some extra motor controllers while you are at it. Use this layout to determine the pocketing pattern and mounting hole pattern. It might be best to not pocket where your wiring channels go to reduce the chance of cutting the wire on a sharp edge. We found it difficult to use Velcro to attach a motor controller when the only place for it is over a large hole in the pan. Zip tying components to a pan with a triangular pocketing pattern can lead to the components being at all kinds of funny angles.

Alternatively, you can install all your electrical components on a thin polycarbonate panel then attach the panel to the pan.

There are many examples of good electrical layout here on CD. You can also refer to the white paper we published for suggestions on how to layout the electrical components.
