Thank you :) Honestly, there's that I would like more than to have a full fidelity razorback Mustang in DCS, they're my favourite aircraft... Ours, however, is not fit for that purpose. The agreement we have with my friend who modeled it for us means that it us for private use only, not to be released. Currently, it is using the P-51D cockpit as a place holder until my P-51C cockpit is ready. She also doesn't have a damage model or a proper collision model at the minute. She's perfect for the formation aero that we do, but not much use for anything else.
Stonehouse, you're correct. Mk III were razorbacks, Mk IV were D models
