I think it is not bug, but it is nessesary to fix it.
wind direction change too frequently. it change every 10 seconds.
i usually play heli with advenced figlt model,
it is impossible to land when the wind blows hard.
wind direction change every 10 seconds and to respond is very hard.
also, it is not realistic!
i think it is more porper that wind direction change every 10 min at least.
