Please define all flight_model.cfg and engine.cfg default values in SDK docs

With all the issue with AE, please define all the default parameters for the flight_model and engines (at least). I never know if AE has messed something up or is correct.

I would be nice to have a clear documented reference of default parameters.

flap_to_aileron_scale as an example - I have this as 0 not sure why, but I would assume a scaling is should be 1, as don’t scale this (as in multiply by 1), Having zero is don’t scale this? (as in add zero to this)
