That is way too turbulent, they ran smoke to check for turbulence, there is no way that you can tell if the model was causing the turbulence or whether the fan/flow straighteners or lack thereof caused the drag.
Are DIY wind tunnels and 1:18 models connected to a load cell a viable test? Or is it not possible to get the wind speed high enough?
