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 Head Speed" 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.
We want to increase accuracy and compatibility of this App. So please help us and send feeback to firstname.lastname@example.org
Please supply information about the phone and helicopters you measured the headspeed.
If you have any problems measuring correct headspeed please contact us at email@example.com

Through the calculation frequency, the sound is analyzed to determine the revolutions of an engine.
It is necessary to indicate the characteristics of the engine prior to reading.
May not work on all engines. It works worst with engines with the exhaust sound very muted and mechanical noise engines (air cooled engines).
It is normal to show some value even if no motor function.

The application is very easy to use - the smartphone screen is displayed speedometer with a special font that with the right size and quality is reflected in the windscreen. In addition, you can track the speed chart in the history of time saved automatically include data on the maximum and average speed, trip distance and the date of measurement.

With the tool you can identify very easy and very exact the value of the pitch from a rc-heli in the following three different ways:
1. By using a yardstick.
2. By using the mobile camera.
3. By using the mobile sensors.
Process for 1. and 2.: You have to scale and type the rotor blade length (hole to end). Both blades has to show in the same direction. If you have 0 degrees pitch the blades have to be exact parallel. If you change pitch, the blades are moving apart. By using the gap between the blades you have the pitch value.
Process for 2.: By using the mobile camera it is enough to type a nearby blade length in the programpart 'calculate pitch'. After selecting the camera icon, you have to make a photo from your blades of the helicopter (like the title picture). Then you have to move the lines upon the blades. The ends of the blades are less important. Important is, that the lines are upon the blades (parallel).
Process for 3.: You can fix you mobile at a blade by using an elastic strap and read the pitch from the display.
- Bugfix: If no camera app is available.
V 2.6.10 / 2.6.11
+ Pitch with Sensor: Movement now a bit smoother. I have changed the method of painting the view. Maybe it has fixed the Samsung Galaxy 2 bug. If the problem is still existing, please send me an email to email@example.com with a short description. Then i can give you test versions.
+ Look is now android version independent.
+ Pitch with Sensor: now you can change the sensor orientation by using the menu. It is useful for some mobiles, because of different orientations. (Thanks to Volker)

RC Heli Logger makes flight and maintenance logging as easy as it gets. Choose your models from our list of over 50 pre-listed kits, or create your own. Logging a flight requires just a few taps, but where this app really shines is when logging maintenance. Our database breaks each model down to discrete part numbers so that you can keep track of exactly what broke and when you replaced it. You’ll never again have to guess which ball links might need preventative maintenance, or which thrust bearing broke on that last flight. It’s all right at your fingertips.
Best of all, all flight and maintenance stats are tracked across the user-base to provide the most comprehensive information about longevity of parts. You’ll receive notifications when any one of your parts is reaching it’s expected lifetime so that you can replace it before it’s likely to fail.
When our users log maintenance on their helicopters, we keep track of how long the part has lasted. Then for every individual part we average together its longevity, thus getting a baseline on how long the part will last in a helicopter. Even though you don't interact with people directly, the more users that use the website, the more accurate the data will be.
Important gear parameters are revolutions per minute per volt (Kv), the engine voltage and the ESC value in percent.
The gear is defined with cog wheel positions at the shaft and the cogs from the cog wheel.
The program has presets for the helicopter: AcrobatSE, Align T-Rex 250SE/450/500/700, Compass Atom 6hv/7hv, EXI 250, GAUI Hurricane 425, GAUI X5, Herobo Embla 450E, MSH Protos, Outrage fusion 50, SAB Goblin 700, Henseleit TDR, Nova7.0
How to use:
- short touch activates / deaktivates the gear wheel
- touch and move changes the cog count
- long touch (1sec) without move changes the gear wheel in a gear belt
- Change it by touching the name or rpm.
+ Now you can use 4 or 7 shafts.
+ new presets: Henseleit TDR, Nova 7.0
+ small changes for android4
+ new presets: Herobo Embla 450E, SAB Goblin 700, EXI 250

Dental RPM Plus is a high speed acoustic rpm meter fully capable of measuring high speed air-driven handpiece free running speeds up to 550,000 rpm. Its capability in electric handpiece rpm has not been fully explored. At this time, this app is not recommended for electric handpieces. Dental RPM Plus makes very accurate measurements of high speed handpiece rotational speed with its proprietary frequency analysis algorithm that distinguishes the sound corresponding to the shaft rotation from other noises generated during handpiece operation. Even in a situation where multiple handpieces are operating simultaneously, it correctly captures the nearest handpiece’s rpm. The app also reports the peak noise level (A-weighted) of handpiece at the time of measurement. This app is compatible with all Android devices with Android OS version 2.2 or higher. A patent is pending on major features of the app including its functionality and frequency analysis algorithm.
- Steady-state speed in revolutions per minute (rpm) between 25,000 and 550,000 with an accuracy of ±2584 rpm within 10 cm to 3 m (4 inches to 10 ft) distance from the handpiece.
- A-weighted noise level with an accuracy of ± 3 dB. Recommended distance for dental handpiece noise measurement is 45 cm (18 inches) from the head.
- Hold button to freeze the reading (hit again to resume).
The app will display 0 rpm upon launching. Hit "Set dB" button to start (while handpiece is not operating).
