Question, what is a good tachometer? I've done some research and found there is a iPhone app called helitach and an Android app called heliheadspeed..
Would I be better off ordering a $14 tachometer from Amazon? Or would the $3.99 helitach be good?
The $14 tachometer from Amazon is one of those laser tachometer's.. I think it is used in other applications besides heli's..
iPhone app or $14 laser tachometer.. What's better?
