He definitely is. Like the TFC Aeriabots, it's not a huge size boost. Maybe just a 20% upsize. But this version is absolutely bigger than the official Airburst if you have them both in front of you. zmog
+1 to SMOG, it's been proven already by tigerblade, AirBurst IS oversized slightly, as well as simplified a bit and hybridized from the old fansproject explorer weapon/tailfin adaption.
