I’ve actually 3 points of the AP, that I don‘t like;
- the aft upper fuselage longeron, where it goes, right into the back of a pilot if things go wrong, I’d rather have in one line from the wingroot going aft.
- the landing gear, it might be stout as only possible, but it looks for me like molehillkiller, a better gear arrangement would be the one of the Ranger.
but, couldn't you think of three things you don't like about any plane?
- last the FlightControl arrangement, I don’t have a straight idea, but I’ve seen some neat solutions on Affordaplanes in the www.
I have such a hard time adding fuel without spilling any, I mean almost always a dribble goes somewhere unintended. It is probably just me.
