Close, but not quite right. At 4:05, using force is cheating. That's what I did at first too, but you do not need to use force at this point - there is another way. From there: - move the long-tail piece so its tail is pointing to the right (3 o'clock position) - lift long-tail piece so that its tail is pointing striaght up - keeping it pointing straight up, you can rotate the long-tail piece clockwise and then bring it down around the 7~8 o'clock position, ending up in the same position as 4:13 in your video Cheers!
