It's as Zero77 writes. Several years I have the Su-25 work every day as crew chief, and then again as contractor during repairs.
For modeler is the most important of all camo is inaccurate. Additionally or colors reversed (green-sand ), ignorance of Soviet regulations of camouflage aircraft.
Decals are at least proportionally for Czechoslovakia completely wrong and in bad colors.
The instructions are again a mixture of both models Su-25 and Su-25UB and they differed significantly.
And now shape. Trumpeter mixed in one model All versions Su-25, Su-25K, BM, UB, UBK T. So it looks as the F-16A, B, C, D, E, F all series in one. Most are on the ailerons. Used only in the plane until 1986, later it had only 12 Czechoslovakia, and the right not trimer. And there's more.
For me, all the Soviet aircraft from Trumpeter are a big disappointment.
