The rudder hinges are Robart hinge points. My first attempt at using them. The installation doesn't look as neat as some that I've seen. All of the other hinges are Dubro flat nylon type. I took everything to my brother's house because he has a slot machine, and he cut the slots for me. But, I really didn't take everything; I left the rudder (or the fin) at home. After I realized my mistake, I decided to try the hinge points since I had them in the drawer. I need much more practice with them to be able to do a neat installation.

Moving the hatch might be a good idea. That way you can put a canopy of some sort on top to give a bigger side profile.

I thought about side mounting the engine but ended up not doing it. It would keep the plane cleaner.
