Huge help there! Not trying to seem as if I am stalking your build notes but I was curious about how you channeled the battery to esc cables through the firewall. The pictures you have posted never seem to show those details. In addition, it looks as if you have built out the battery compartment to create a space a bit aft for the batteries. That raises two questions. First, could you post some pictures of you battery area, and second, what is the weight of the 6s units you are working using. My 6s 5000 mah Admirals weigh in at 25.4 oz each. As always thanks for sharing!
