Analog tach replacement

I highly recommend having this feature and its relative, "mag drop".
It would be a shame to switch to an electronic tach without getting
such basic features as a result.

In fairness to the R-1, it does have the "mag drop" feature.

O.k., I'm stumped. How can it tell you that it's measuring mag drop
without telling you that one of the mags isn't firing?

ah - I think I may have been confused and thus confused others. I read
"mag drop" and assumed you meant "RPM drop" when checking mags during
a run-up.

I was using the same definition. I'm trying to figure out how the R-1
can say "here's the drop in RPM due to one mag not firing" without
the operator figuring out that one mag isn't firing.

I thought you were asking how it worked and decided to provide a complete
description for the benefit of anyone who is considering one of these.

Looking more closely at your post, I see that's not exactly what you were
saying.

I just want to be clear here. Your message had nothing to do with the

When you press both the flt time and tach buttons, it (temporarily)
sets the RPM LCD display to 0 - thus prepared to show RPM drop during
your mag check during run-up (as well as the check of carb heat).
