I was thinking of putting 2 3s packs in front of the spar and 2 behind. might be able to make a nice hatch to cover all of the rear packs and most of the front ones. it looks like some 2700 3s zippy compacts will fit side by side in the center section.
that was my thought until i started looking at the pylon racers and hotliner setups. holy s#!t those things are fast! might be changing my plan lol
