Progress is going well. I have made up some temporary battery trays (I'm going to make the permanent ones from CF) from 3mm alloy, I'm going to take to them with a drill to reduce some weight this weekend. I have attached a pic with the tray and my fake batteries (my 3 X NEU 2S1C 5000 mAh are in the mail) as you can see it looks like the L/R weights should be close. I will know more when the packs arrive.

I have also attached a pic (far left) of my temporary motor mount system (it hasn't been line bored or machined for weight reduction) it is a simple band clamp setup for testing only, the permanent one which I have nearly finished deigning will be CNC'd and include a integrated 12 fin heatsink and will still be a band type clamp. It will use the original 21 size motor mount bolt holes as well. A friend is going to transfer my hard copy to CAD so if anyone in the industry knows what format I need to give the machining shop please let me know.

Still waiting on the motor (NEU 1512 1.5y/s) to become available from Mike's shop so I can order the speed control and motor at the same time. Hopefully they arrive soon so I can get this thing up and running.
