I have never really like the look of the bottom hinging either, but you may be able to program in enough differential without changing the hinging at all. Experiment and see what you think.
Once you get it stripped, you may consider beefing up the lading gear legs (which may require a new mounting method to the fuse). That has always been one of the major weaknesses of this model. Especially considering the 1 lb lead block and everything else in front of the firewall needed to get the CG right.
So many great color schemes and possibilities. One thing that comes to mind immediately is adding the distinctive oval engine access panels on each side of the fuse and may as well add the carburetor intake tubes as well. Easy to do and would add a lot to this model.
