Thanks GFR, that is the plan really. It's not gonna take long to create the slight changes between the variations it's mainly just:
A-5: Different engine (on later models) so different exhaust stack config and a few little details on the fuselage, oh and the longer wing which I'm about 90% done with already because I created at the same time as the short wing.
A-4: Slightly different tail, larger wheels and again different engine so exhaust stacks and some elements of the power egg.
And then many different armament/armour and B-stand/C-stand canopy configurations for all above models. But yeah the hard bit is almost done. Then about 500? different markings schemes to churn out.

Then maybe move onto the more specialized versions?
Peter K: I don't understand what you mean? Does anyone else notice this? Could do with sorting it if there is an issue.
All comments and crits are welcome to get this one spot on gents.
Thanks
Clint
