SR71 or Aurora prop plane?

[FninjaP90]

Is it possible to build a scale SR71 or Aurora spy plane, aerodynamics wise?

Hi,
Yes, it is possible. It would be wise to plan on a propeller version being a pusher. This would balance better, and there would be no spiralling propeller flow over the model to upset the aerodynamics.
