bgnasdy,

The Top Flite canopy off the 1/7th scale Gold Edition kit is basically the correct scale dimensions for a 1/7th P-51 - about 1" longer than the H9. Unlike the H9, the TF framework and overall canopy shape are correct, too. You can buy the Top FLite canopy as a spare part from Tower Hobbies. Unfortunately it takes a bit of work because the top of the H9 fuse is not exactly the same profile as the TF. The more correct TF exhaust ports and the gun blisters would probably work as well. None of the TF stuff is painted, not even the frame on the canopy.

This is only if you are pretty anal about the scale looks. For most people the H9 Mustang is probably fine the way it is.
