Please EMAIL if you have a problem, we can NOT help though the comments section.
Use RC E-Calc Pro Calculate the following:
- Average Current Used by the aircraft during a flight/run.
- Average Discharge Rate (C-rate) of the LiPo battery during a flight/run.
- Expected Run Time at average current used.
- Expected Run Time using 100% capacity of a battery.
- Expected Run Time using 80% capacity of a battery.
- Realistic Run Time using 80% capacity of a battery and (selectable) average throttle.
- Power in Watts from Volts & Amps.
- Volts from Power(W) & Amps.
- Current in Amps from Power(W) & Volts.
- Static thrust of a propeller in pounds or kilograms.
- Power to Weight Ratio in Watts-per-pound or Watts-per-kilogram.
New for v2.1:
- Unit Conversions (Torque, Mass, Length)
- Cubic Wing Loading (Imperial and Metric)
- Wing Loading (Imperial and Metric)
New for v2.21:
- Resize and refit for better display on tablets or devices with very large fonts
- Reworked Unit Conversions
- Cosmetic improvements to layout
- throttle value choice in Approximate Flight Time
New for v2.3
- Added Battery cell gravimetric energy density calculation in Wh/kg
- UI enhancements and fixes
- Smaller fonts
- Cosmetic improvements to layout
- Unit Conversions improved
(Note: It is highly recommended to fly using only 80% of the capacity of LiPo batteries to maximize their longevity)
a) If your system uses 16 Amps, input 2200mAh and 16A into the app and it'll calculate that you should be able to fly (at FULL throttle) for 6 minutes 36 seconds until the battery is 80% depleted or 8 minutes 15 seconds (also at FULL throttle) until it is 100% depleted.
a) "Realistic" flight time is also calculated which works out to be 11 minutes and 47 seconds using 80% capacity and 60% average throttle, very close to the actual flight time in the second example.
b) You have flown (or driven) for 11 minutes and 20 seconds, then recharged your 2200mAh LiPo, when finished your charger states that 1720mAh was returned to the battery. This app will then calculate:
- that the average current draw for the flight was 9.11 amps,
- the discharge rate was 4.1C,
- you used 78% of the rated capacity of the battery and
- to use 80% of the battery's capacity you could've safely flown for 11 minutes 35 seconds.
Comments & suggestions very welcome, please email if you have problems as we can not respond to Google Play Store comments.
Disclaimer: The formulas used in these calculations come from various internet sources, with some variations added from my own experience and while a lot of effort was put into ensuring accuracy, your results may vary!

Enter the transmission ratio, spur, and pinion to generate Final gear ratio.
Enter tire diameter, motor KV and battery voltage to get potential speed and max motor RPM.
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: pitch with sensor (for some devices)
- 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)
V 2.6.7 / 2.6.8
+ Graphic improvements (Pitch with sensors / number wheel)
- Bugfix: OutOfMemory in Pitch with sensor
- Bugfix: crash program, if an old value has not a valid value. (Thanks for report.)
+ Graphic improvements (Pitch with sensos)
+ Input of numbers now with number wheel.
+ move to SD card (with Android 2.2)
+ Now with min and max in 'Pitch with sensor'. Min and Max are applied, if the pitch value is 2sec fix and greater then +/- 2°.
+ Pitch is not bouncing this hard any more .
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.
Use onscreen wheels to adjust spur and pinion gear sizes to view final drive ratio. Use the onscreen wheel to adjust tire diameter to view rollout.
Save an unlimited number of car profiles for different models and setups.
Free version is fully functional!
Based on the CalcRC www.calcrc.com.
Includes calculation of the maximum speed, oil viscosity conversion, battery charging time calculation, conversion values servos and finally calculate the size of the gears.
