You are going to want to get DSA on there one way or another.
My guess would be shrink the chassis by attaching motors via snappers (you could use the wedge snappers, although Snapper IIs suck for wedges), or switch the irons to razor tips.
OH MY GOD IT'S JAWS!
Since all you guys have been begging me to add Z-teks, here ya go. Downgraded the weapon motors to Z-teks and added Z-tek drive. The wedges seem better as well.(Image removed from quote.)
I'll do that next time, but keep in mind, I'm really lazy.
And you've inverted the colours on the wedges, haven't you? =D
J24, please don't quote massive images straight away.
