the H-9 mustang,or any of the H-9 planes for that matter, is more of a sport flyer in warbirds clothing, at less than 8lbs it is a floater and has a slow approach speed for landing,and hardly any tip stall tendencies.

the spit on the other hand does have those splayed out gear and can be rather tricky to land,a club member had one that he ran electric,it flew nicely untill his battery went south on him, and he turned it into a pile of rubble, we have a bit of a trecherous field if you don't hit the landing strip.

the sim is a tool for advancement, its surprising how much I improved with practicing with it,and even if I don't fly for a while and just hit the sim to keep tuned up its like I never left the field.
there is no better way to learn then by actually flying but the curve is lessened with these tools, as well as these easyer flying planes there not like a 11lb Spitfire there so much lighter and easy to handle they really float and require less flying on the wing like a "real"warbird that when power is pulled back sinks like a rock and tip stalls.
