Either in December or January I remember reading about a scale version of Anka-3 flying, I don't understand why people keep thinking this is not the end product? This was never going to be a B-2, it's dimensions are pretty much on par with other delta wing drones that have been seen so far. Maybe in the future if this is successful TAI might make a bigger version but this is most likely it.The scaled version that was talked about could be the demonstrator. Maybe as it was said that demonstrator already flew and this is the prototype of the full product.
Of course there might be changes between this prototype and serial production model but I doubt there'll be radical changes. Thinking they'd make a demonstration model this big is just ridiculous.
