I kinda like the, "ornery" props. I've never flown (as PIC), any piston aircraft bigger than a Cessna 310.. but I have sat right-seat in a Convair 240 (kinda like a tricycle geared DC-3). Those big, old, grumpy radial-engines, and their equally grumpy props are NOT the precision instruments you'll find on modern GA. It's more fun (and actually more realistic), to NOT be able to just dial in an RPM and count on it holding.. I like the "hands-on" prop management.
As for the loading.. yeah, loading the aircraft is as much a part of flying, as navigating. Paper and pencil (or experienced guessing) is good.. so long as the weight-stations are there at the 'Fuel and Payload' screen.., with at least a basic description for each... and the difference between empty weight, and max weight (useable load) allows for loading. ... I.E.. 6 passengers and their baggage means not only deciding where they'll sit (and where the bags go), it also means less than full tanks (110 gallons each). Let all the passengers sit in the forward part of the cabin.. and prepare yourself for a twitchy airplane.. LOL .. Pile in 10 passengers (aux seating) with bags, and you aint going very far...
As for actual in-flight handling.. it gets tricky. You have to compromise, because much depends on the hardware. A person with a springy, joystick and twist-grip rudder won't be able to realistically control a model that is set up for realistic handling. That requires more subtle and precise controlling of a yoke and pedals.. and ideally, you'd have a throttle for each engine... not only for ground/water steering, but for yaw management, and even crosswing landing. A person concerned enough about accuracy there, will figure out how to tweak the cfg file. "My" Goose would be almost unflyable by twisting joystick and single throttle... and if you don't manage airspeed/manifold-pressure during a climb.. the engines will overheat :isadizzy:
