yeah the thing is that the L 39 and Yak 52 had the profit taken care off, by a private buyer, they allready HAD the planes in the sim, why not sell them also .
Regarding, Modern Russian aircraft: Still, the risk is big, you can mount a subsidiary anywhere, one day Russian Gob. decides you are a threat to security and thats it, no more ED in Russia...
It Does not matter who builds the module, ED is implementing it...
