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.
