Don't have a Tacho.
Strange value ...

It sound a bit too slow for real.

I'm sure my RadjJet fly over 70km/h.

And with my Turnigy Anemometer (that I just find by battery is dead, after many months of un-usage) .. it gave me always the impression was measuring more then the reality ...

Best things are the little optical tacho (it must cost 10$ in these days) .. the RPM reading is always accurate ... even better is the digital rpm ... but it is not practical if there is no access to the motor cables
