Very Funny build no doubt! Very speedy and makes good use of the 3M's engine. Since I'm trying to assign an XL280/XL300 to this chassis I'd upgrade the autocannon to a scarier variant: or you could do a mini-meta kind of thing
I've been running something similar to this as a fast scout-sniper with the addition of Newtech - you could use any variant of AC5 and a Light PPC with a Light 280. As far as a Cicada goes, it's a fairly effective little build for harassment; but it's by no means ever going to be meta. Guess that makes it more fun for me.
XL300 may also be interesting. It's basically an AC10 with longer range as you describe it, AC5+Lppc is really nice imho.
