I grabbed one of these from a JB Hifi while Christmas shopping.

Engineering wise the figure does some nice things, it's painted well and theoretically would have good play value, except that the one I got is a complete mess of quality control.

My copy has only three solid tab connections - backpack tabbing onto the back in robot mode, and the triceps tabbing to the underside of the wings in jet mode. Everything is is a floppy mess, crucially including the tab that is meant to hold the legs flat rigid in jet mode (back of hip connecting to folded up robot backpack), and whatever mechanism is meant to hold the cockpit in place. End product: grab the jet mode by the cannons and both the front and back sag with just gravity.
