Another thing to think about:

Flaps -

how fast to they deploy and how far on the real plane. Do you keep the same angle and rate at which they move from retracted to extended position. And then to complicate matters do we really have to prove to the flight judges how far the flaps extend, at the Nats one year the judges wanted to see the flaps and retracts move before the flight, but no proof was offered to how far the flaps were extended and how fast they move.

Landing gear -

take the AT-6, the gear retracts with hydraulics and the port and starboard gear retract at different time and rates. Do we ever prove how fast the gear retracts, does it take 5 seconds, 10 seconds or 20 seconds? obviously the gear up in 1 second with air (un-restricted) is not right but if we slow it down how much is scale and how do you prove it. And do we even have to prove how fast the gear retracts.

My vote is make something that looks right and has good flight realism.

Scale speed as already been discussed, cubs fly slow and fighters fly fast.
