Really surprised, had been using a optical tach and I didn't want to work early in the morning or late at night also had 20 RPM increments , to my surprise I'm getting readings down to a single RPM and even after in flight not just checking the head speed on the ground before liftoff
As a Senior Java Developer I have to say that this is truly an amazing app!!!
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!
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.
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.
On point! This app is very accurate
