In the G1 series, blitzwing was a triple changer that had a robot mode, jet mode and tank mode. MOCers often find it difficult to allow the transformation between the three modes. Also, most toys of blitzwing have failed miserably to create him, especially the animated version (man, it sucked!). But, I think I did an okay job. Its not perfect, but its okay. Anyway, he also comes with a minicon. It transforms from a jet into an antimatter blaster. Basically, it fires antimatter that instatnly explodes on contact with anything. Problem is, it takes a while to reload, and by a while, I mean 15 seconds. Still, its pretty cool. I'll upload the instructions soon(ish).
