From looking at their video, they are using the version that you guys refer to as the "misassembled" one with the peg that looks like this in alternate mode:
So Taktom are using the same ones that everybody else seems to be finding in their stores but they have modified some of the pictures in the japanese instructions such as "Changing to battle mode" Step 10.
The cab part does fit properly in robot mode provided you flip up that dark grey peg as per "Changing to robot" Step 13.
Just ignore some of the details in the printed english instructions.
However, i still cant get the mode 3 to resemble anything like the instructions nor Kurt's pics (btw, they are really well taken photos Kurt!!).
I might have another go at it later when my cold/flu clears up....
