Thanks for the info, Gok. I've updated the main review and opening details accordingly.
It's a little odd that Hasbro/Takara didn't try to make the toy a plane that approximated the Gripen. I could see that the toy's body looked like a stylised F-16, but I had to do some searches to try and figure out what the front of the plane was inspired by.
I haven't done it on mine, but apparently the problem tabs you pointed out can be loosened with a screwdriver so the leg goes in and out more easily.
Is there a source for this? I was trying to find one so I could cite it for the review. It just seemed to be a thing that everyone was saying.
