Hmm
I’d say the shock bumper on the nose wheel is a very very good one for nose strut planes who want to places that may be bumpy
Remove the wheel pants
Tires (and tailwheel system) big enough the plane doesn’t feel like you’re going to crack something when you touch down, or are sinking into the ground, anything bigger is just a negative in performance
Panel wise, a AoA is nice, though the GA retrofit ones are not true full flying AoAs,
I’ve also toyed the idea adding a variometer to my 7AC to better take advantage of the yuuuuge wing around mountains and in the summer
Not part of the plane as much but a iPad with foreflight and all your reference docs,
it’s nice to have the 3D day/night view of places I might land, and to be able to reference text search everything from my POH, overhaul manual, FAR, SEAR manuals, plant identification, property lines and owners, radio frequencies, bathometric data for rivers and lakes, IAPs, etc Plus the obvious moving map GPS
Per Ford, well have you have made the Kessel run in less than twelve parsecs?!

I haven't seen it yet but I can picture a crazy person who shows up at a backcountry strip on an
airbike with a backpack of ultralight gear and sets up for the night. Now would I do that - heck no, but whoever does would be a hero.
For me the primary drivers are:
- aircraft capable of carrying me +1 or more with gear to the strips I want to visit
- speed and fuel capacity for convenience of getting out for an overnight or weekend trip
- envelope large enough so the above is satisfied while also being able to crash into the trees with a likely outcome of scrapes and bruises instead of splattered to pieces.
- let's be honest, has to look cool too(sorry Maule, that's a tail even a mother would be ashamed of

).
I have a buddy who converted a J3 to an L4 clone who gets in and out of some pretty cool places. O200, no flaps. He weighs about a buck o five and generally doesn't/can't carry passengers to shorter mountain strips but it works for him.
Any airborne rig that gets me to cool places where I can spend time in the woods with or without friends new and old is good by me - flaps or not.
