I realized that this was not a commercial product.
I just ask this year will be something else or not.
Also, I can not get the SR-71 with rocket Volkhov they reach 10 km by!
I tried several times to the Volkhov in any way.
They reach the rocket goes away.
It is not clear at all.
As for the method to know, I just need to inc. Work on R3 or not.
As I understand work on K3 needed if the height of at least 300m.
At what distances have to shoot at SR-71 Volkhov.
