Simply works! Does what it says and compares in accuracy with optical and telemetry readings for my 450, 500 and 600 electrics. No complicated setup or guesswork required. Awesome value!
Fantastic it works Three blade Trex 700 is now easy to measure. I was doubting this app, but the thing works, and pretty well too! Nice one.
Accurate to +/- 20 RPM Verified against MA skytach and onboard telemetry. This app was within 20RPM on 450-700 electrics and 600-700 nitros (not saying it doesn't work outside of those, that's just all we had to test at the time.) It's a great little app.
On point! This app is very accurate
Handy tool to have.
Excellent app, easy to use, highly recommend I have compared this to other tachs and telemetry sensors and it's very accurate. It's easy to use and works surprisingly well. Used on 450 electrics, 550 and 600 nitros with equal success.
