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.

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.

David Greatz

No menu on G5 Galaxy Only have the tacho page there's no menu screen or settings available....update to problem. .press and hold page key to access menu. Thanks to developers for finding this out . Cheers

Works exactly the way it is expected. Great app, especially when you dont have someone present to tach the disk for you

Steve Kimberling, Jr.

Thank you! Very helpful verifying my governor settings.

Stephen Elsworth

Samsung s2 App works well, I have been using this app for my 450 size heli and a few other larger helis. It seems to work well.

wahyu endarto

Very accurate, prety close to esc calculation

Chen Li

totally worth it!! used it today on my note 4 to measure head speed of my x3. work like a charming.

A Google User

Great app! Does what it's supposed to do. Great customer support also. A+

Bryan Pederson

Works good Seems like it works alright, was able to differentiate between two different battery brands I use.

Brandon Na

Not great for micro helis such as the MSRX and NCPX I am sure it would be different with a larger heli. Will only show intermittent readings and they fluctuate wildly.

Headspeed tach Excellent app. Very close agreement with my optical tach. Much easier to use. Checking 500 , 600 and 700 size both electric and nitro.

A Google User

Awesone Works perfectly. I like it better than the other head speed tach app.

Ralph Gustafson

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

Aaron Bean

Estimate headspeed!? 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.

Top No problems using this app.

Mark Bennetts

No more guesswork Great simple app, and pretty accurate too.

A Google User

Love it!!! Excellent and very Accurate.

Excellent tool Works well, HS compares OK with conventional mechanical tacho.

A Google User

Awesome Sweet app! Love it, compared to my buddies 100 dollar tach this definitely holds its own!

A Google User

Head Tach Simply works.

A Google User

Works great Very happy with this tach.

A Google User

Yup Works really well, no fuss.

A Google User

Easy to use and works well!!! Works as it should. Great tool!

A Google User

Darcey Works as described. Seems to be accurate on Droid X. Wish there was a way to review past results. Maybe that can be a future rev. I would recommend

A Google User

Was Within 5rpm of accurate calculation My Trex 500 FBL has an actual head speed by calculation of 2889. This measured at 2990. Works as advertised. Great little app.

A Google User

beenflying Works well. Great value. Much better and safer than optical tachos.

A Google User

Real nice Great app even works great on my smallest heli (BL mcpx HPO8 and 915 motors. Be blessed Isaac

Ilya Tyshchenko

Just work as expected Differences w/ optical tach about ~20-30 rpms. Very good result!

Bill Inman

Handy tool to have.


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!

Sydeck Coleman

On point! This app is very accurate

bob holkan

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.

Ryan cal con

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.
