Mig 21 Angola Air Force

Hi guys,
This is my interpretation of a MIG 21 MF of the Angolan Air Force.
It's the MIG21 MF Eduard kit, 1/48th.
This kit is really easy to assemble, the fittings are nearly perfect and the putty almost useless. The cockpit was upgraded with the dedicated pre-painted photo etched from Eduard as well. The setup is a bit touchy, but I' think the final result is worth the effort.
I' used Gunze paint, except for the underside were I' had to use some AK "Air". I 'bought a set of this brand a few month ago....just to try.... and will never use it again : the paint dry in the airbrush, whatever the dilution quantity or type that you use (water, alchool, mix, etc...) and eventually it doesn't resist to the wipe when you want to remove the excess of wash on the surface. It's a mystery to me how some modelers can use this type of paint.
Thanks for looking.
Bye
Didier
