Your model looks good any way but if the engine development allows a better version.. wonderful.
With regard to my Harrier (is both an FRS1 and FA2 version) for MSFS it is available at simviation.com and flightsim.com(on this site file names are ukmilrs1.zip and ukmilfa2.zip) plus the UKMIL site (www.ukmil.org.uk) but I think you have to be a member to download it from that one. UKMIL did the panel for me as I had no knowlege of how to do that. Its not a bad model but as always you look at it and think ... I could have done that better now.
I dont want to give out my email here and there doesnt seem to be a provision for personnel messages here but if you can think of a way of getting your email to me I'll send you some drawaing details that might be of use.
