Sorry should specify. With an RC plane moving about 15km/hr, if I want to make the wing 1/5th of the size of the original, I need a windspeed of 75km/h to maintain the same reynolds number. to get a windspeed of aout 75km/h, I need a smaller windtunnel compared to the size of the fan. Does that make sense? Maybe I am saying gibberish
