About Headspeed Tachometer
Headspeed Tachometer is used to measure the headspeed of your r/c-helicopter.
The sound of the blades will be analyzed and the according headspeed will be calculated.
Using Settings you can choose between standard (rpm up to 4000) and micro sized (rpm up to 8000) helicopter and setup the number of blades between 2 and 5.
Before starting the measuring you have to set an estimated headspeed. You can expect most accurate measurings if set inside the range of +/- 500rpm to your real headspeed.
Works with electric and nitro helis without changing any settings.
For best results please follow these instructions:
Make sure you have not too much side noise like strong wind.
After setting an estimated headspeed place your phone on the ground 1-2m from your helicopter.
Press the "Measure headspeed" button and walk to a save distance.
Spool up the helicopter to your desired headspeed and wait about 20 seconds.
After the blades have come to a stop retrieve your phone and press the "Stop measuring" button.
Now you can read the headspeeds during the measuring.
You can save the result to the log history using the menu option. If you enable the option "Save log automatically" logs will be saved automatically after finishing measuring.
Touch a log entry in the log history to view saved results. Long touch a log entry to send the entry or delete it.
Use log menu to send complete log history.

Please supply information about the phone and helicopters you measured the headspeed.
If you have any problems measuring correct headspeed please contact us at android@id-mobile.net
We will give you instruction about how to enable debug mode. This mode will write data to your SD card which can help us find a solution.

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.

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!

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.

I am sure it would be different with a larger heli. Will only show intermittent readings and they fluctuate wildly.

Right on with all of my other tachs (with in 20 RPM) Loggin & Setup easier rhan with the orher Apps that I have tried.

Umm, the whole point of a tach is to determine rpm. In order for this app to read, you have to "estimate" your rpm?! I have no frikkin idea how fast the rotor is spinning! Isn't this app supposed to tell me that? If I select 8000 rpm as an estimate, the app will tell me my rotor is spinning in the 8k rpm range when I have just barely started it spinning. The same for the opposite end of the scale, full throttle will yield head speed readings in the 3k range.

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
