SR-71

I’d like to see a simple, mini and a master build of an SR-71 Blackbird some day. I imagine the mini would be pretty easy, the mini would be fast and the master series… awesome!

Quite apart from any weight/wing area issues building a true scale EDF SR71 has a fundamental problem. The inlet "spike" occupies a huge proportion of the inlet area.
To keep a scale size spike would mean using substantial "cheat holes" to ensure the fan got sufficient air or use a much smaller size spike.
However by placing the fan right at the back of the nacelle in the convergent/divergent nozzle it might be possible for the total of all the scale inlets to provide sufficient air to the fan.
Just an idea.
