The app supports various engine configurations, ranging from Micro to Supermax classes.

Current Momentum

v2.3

• Added ability selection of carburetor restrictors for Mini and Micro engines (RTX251730, RTX267530, RTX267535, or without any restrictors) • Added new feature: get weather (temperature, pressure, humidity) via Bluetooth using weather stations: Kestrel DROP, Kestrel 5x00, WeatherFlow WEATHERmeter, Skywatch BL • Added new feature: added the ability to calibrate the barometer built into your phone or tablet (go to the “Settings“ tab, then “Measurement units“) • Added new feature: added various utilities (unit converters) (go to the “Settings“ tab, then “Utils“) • We have improved our weather calculator significantly. Now you can manually select which type of atmospheric pressure you are working with (for example if you use portable barometers, weather stations): - sea level pressure QNH - sea level pressure QFF - station pressure (barometric pressure) • Now, if you don’t want to see intermediate (half-steps) positions for the needle, you can turn it off on the 'Engine' tab • New type of fuels have been added: VP Racing MS93 and 93 AKI with ethanol. Please check which fuel you are using • On the results tab, click on the drop-down menu 'Weather (AirLab)', new data for tuners are available: Air Density, Relative Air Density, Density Altitude, Station Pressure, SAE - Dyno Correction Factor, SAE - Relative Horsepower, Volumetric Content Of Oxygen, Oxygen Pressure • In the 'Results' tab, we added recommendations about spark plug gaps, positions for idle adjustment screw, optimal water temperature, gear oil recommendations • Improved functionality and accuracy of fuel calculator • Bug fixes for "share setup with friends" feature • Added new type of spark plug: NGK Rotax • Improved functionality for the feature 'Weather for custom location'. We added a search bar where you can enter the location name. Search places easier and faster now • We reworked the altitude determination algorithm for the 'weather for custom location' feature. We hope that now, if you manually selected your location, the altitude will be calculated with much greater accuracy • We added the ability to leave text notes for each history in 'History' tab. To do this, open any History, enter edit mode and add a note • Now you can manually select the translation language. Application contains many special terms and sometimes translations that we offer are not always good. We are sorry. Now, if your phone (for example) in German, but you are unhappy with the translation you can switch to English (for example) only in this app (you don't have to change locale of device). You can find this feature on 'Engine' tab at the very bottom
