Thank you Hermann!!
Jean Barby mentioned over on HS Plastic Pix, that the u/c looks long. Well, I am not sure about that and i took another pic. Of course there is some distorsion and the stance of the Tamiya kit is very broad. But you can see, that the legs are equally long as the Tamiya but longer than Hasegawa.

To me it does not look that bad and I just assume that the Academy is empty (no fuel or ammo)
all the best
