Can aerodhead or anyone else verify this 5x part width is tunnel width/height?. I am also starting to study and manufacture my own wind tunnel or water tunnel or even both
. I dont have much problems with space needed. Plans are to built 1:24 tunnel which could fit a "full sice truck in it.
I already have the acrylic sheet for clear windows and wood material needed. Still missing the fans and honeycomps, scales etc.
