Yes there was alot of calculations...formulars...but Taguchi was quite interesting. The fact that one could find a solution to a problem without having to invest so much was great. It was good to see that the experiment worked and finding the design space was quite interesting. We didnt get the optimum out of the helicopters but we advanced in the right direction. Given another trial, we would end up at the optimum design space. Taguchi was an eye opener and I don't mind trying it all over again.
