I've not done anything with sounds, apart from pinch existing ones to use 
in the models I've done, so I can't help you there very much.

I think extra panels can be created without needing to change the 
underlying code, but once again, it's not an area I've looked too closely 
into.  However, if you're working towards a virtual cockpit, you can just 
include all the panels, in their appropriate places in the cockpit, as 
part of the model.  Adding additional views is quite easy and I've done 
this to add a rear cockpit view to the TSR-2.  I've not modelled proper 
VCs for it, with instruments etc, but to do so wouildn't require any code 
changes.

There is some stuff already in FG to handle hydralic, pneumatic and 
electrical systems, but it's not really my area so I couldn't say to what 
degree these things are modelled.

You don't need to tamper with the underlying source code to model and add 
an aircraft to FG, although there are currently some restrictions to some 
aspects of some of the fdm solvers that need to be bourn in mind when 
making an a/c for FG.  You need to have a look at the different fdm 
solvers and work within their capabilities, as far as developing an fdm 
for an a/c is concerned.

While the a/c developers tend to work on their own a/c, they are 
open-source and improvements can be submitted by anyone.  It should be 
remembered though that a developer may already be aware of problems with 
an fdm and has picked one particular compromise over another depending on 
what aspect of the a/c performance they think is most important.  They've 
probably spent a lot of time test flying the fdm, making incremental 
changes to it as they try to refine it's performance, so it would be a 
good idea to discuss with the developer any changes you might want to 
suggest to make sure it's not incompatible with the programme of 
development already mapped out by the original developer.
