True, but this is also several orders of magnitude simpler than a modern combat aircraft. It has vastly simpler dynamics, it doesn't have to deal with control surfaces, it doesn't have to be stable with irregular patches of supersonic flow on its wings, and so on. It'll probably only take three or six years, I bet.
