Differentials in the wrong way around... Hahahaaaaa. I'll let you guys know when it happens to me.
Smooth sailing on the Exo build so far. The hardware is in labeled bags from A-J, in perfect order as you need the parts so far, step 12.
the plastic trees have sent me on a few goose chases, but no big deal.
One tip, don't take any small plastic pieces off the trees without remembering the part number because you can't always depend on the diagram to distinguish what's what.
