While this is well made, in production you would probably put the physics model in Excel with a bunch of VB scripting, and interface it to parameters and equations in solidworks. This isn't something I've done, but I absolutely wouldn't want to trade in a cad engine that can do everything badly just for some design tool that does a few things well.

if you want to get somewhere with this, you should consider the engineering work flow. usually there is a conceptual/design phase that consists of a lot of photographed whiteboards, physical mockups, Matlab, even Mathematica Notebooks if you're like that. Or actually, some cfd and multiphysics fem modelling if you are serious about your flying objects.

You seem to fit into this chaos sonewhere, but I wouldn't quite know at which point I should use this. After all, cad models are always parametric until you start adding all the details, and actual physics modelling even on a xflr5 level goes well beyond this.
