Help! Can someone share their battery mounting/retaining scheme? My new Impact needs the batteries mounted well forward and I want to fit and connect them via the canopy opening. I also want to have a decent airspace between the packs. Oh and I want it to weigh zilch!

For raw material I have some 3mm carbon/bluefoam/carbon sandwich, liteply, 6mm carbon tube and 1.5mm carbon rod.

I've been looking at this for hours and can't come up with anything innovative.

Here is the setup in my existing model which doesnt have any airspace between the packs.
