RE: Best tach for speed engines-
Well, Mr Auger uses a TNC Tach. But that's just the way Mr Auger is. It is very sensitive..no more pointing the tach right at the prop from 1/4" away..just lay it on the ground kinda pointed at the prop and it'll get the reading. I also have a Futaba TachOTimer, it is a nice tach,, but it's not in the same league as the TNC.
