Lol?
Ready for some criticism James?
Shoot the modeller!
Or at least for heavens sake: Don't show an image that just doesn't resemble the real plane.
Wanna know why I've ruled out the MiG at step one?
Because the nose doesn't match.
This is the real MiG-25 PU nose shape:
It is extremely pointed - as is to be expected for a Mach 2.5+ plane - and the radius of the shape's curve radius gets
larger the more you move up front.
This is your model that just isn't a MiG-25:
Note the difference: The nose of your model, or at least that mismatching part you've shown, is
not pointed like on a MiG, the shape's curve radius gets
smaller the more you move up front.
Such a plane would never reach speeds in exceed of Mach 2 without rocket power.
The quest would have been a cakewalk with a real picture.
The one shown is just a fantasy plane, that's been the difficulty here.
