Thanks for the suggestions so far.
I don't plan on flying inverted
all the time.

Since this is a low winger, wouldn't anhedral be inherently unstable flying upright?
I do plan on enlarging the rudder and elevators. I also plan on driving each elevator half with a separate servo. Still haven't decided whether I want to do quad flaps on this one.
I did swap out the stock landing gear with a much more stout unit. I've had many pilots told me the stock aluminum gear is crap. I will also glass the landing gear mounting area as it is reportedly a weak spot.
I agree this kit is such a joy to put together that it's hard not to want to spiff it up with a few mods.
