I will definitely test it out when I get the chance!
Easy. mount the accelerometer on a flat pice of 1/8 inch thick balsa, maybe 3 X 3 inches close or where the choord is atached to the ball cap. Your head will get in the way and prevent it from twisting...

No need to do whacky math. Just vary the length of the chord.

I went through this drill a while back...Here's what I came up with instead...Admitedly, only single axis HT...However, it is REALLY cheap and simple...
