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).

I think it's pretty cool! I like how you made it so he can transform into both jet and tank. I don't remember him from the old show but I saw him in the animated version. Anyway good job!
Although I may be wrong, you should look up the episode 'triple takeover'. Three of the triple-changers (including astrotrain and blitzwing) attack various places, sometimes with hilarious results. It's funny watching blitzwing take advice for his conquest from a footy coach. :P
