How do you get by transforming Binaltech and Masterpieces if you're getting stumped by Axelerators?

If it stumps you that much you can bid on Rapido's instructions here, otherwise here's a text description from that cliffbee guy:
"Detach the engineblock and set aside. Flip over the rear to form his legs, swing out the doors to form the arms (well, the armguards). Stand him up, fold down the front of the car to form his chest, rotate the roof on his back. Swing up the forearms and give Rapido his gun (the engineblock)."
