It is targeted for FrSky OpenTX based RC transmitter systems and integrates support for a wide range of FrSky, as well as third party telemetry sensors that are compatible with the S.Port telemetry protocol. iMSB FrSky offers a state of the art replacement for built in and external telemetry displays, including many more advanced features. Fully customisable iMSB FrSky supports several model definitions and allows tracking vital information from your model. Flight data is displayed in an easy readable form on several thematic views in analogue or digital form. iMSB FrSky not only displays real-time flight data, but is able to record and save flight sessions for later playback and analysis. It can be configured to alert the user when critical values are reached and provides valuable flight time statistics data. Additionally, in order to enhance safety and as modellers generally focus on their model rather than on a visual display iMSB FrSky fully supports voice based commands and announcements. Features: - Define individual models and assign each sensor value available in the real model from a list of available sensors - Support for various thematic displays such as electrical and temperature values, vario, altitude, speed, heading and rpm, as well as flight track and model positioning on a map - Minimum, maximum and average statistical data can be shown along the actual sensor value, as well as a graphical plot of it evolution over time - Freely customise each display by assigning sensor values and their associated flight statistics to individual analogue meter views or digital display fields. The layout of each view can be defined among a set of predefined templates - Individual alarm thresholds, as well as multiple level notifications for each sensor value can be setup directly in the application (no specific settings required at the real sensor level) - Get notified of an alarm by issuing an alarm sound, display a message popup or a spoken notification - Record real-time flight sessions and save them for later playback and analysis - Control replay speed, cuing to a specific position, as well as pausing and resuming playback - Integrated vario sound player - Compare flight to flight, as well as model statistics. Plot several values simultaneously on a time graph for further data analysis - iMSB FrSky incorporates a flexible voice based application navigation and command set for controlling various application features, requesting the announcement of a sensor value or even a whole set of values - Displays sensor data in metric, imperial or nautical units - Possibility to export flight log data over iCloud Drive, Dropbox or OneDrive in the LogView Open Format Zero (csv), Google Earth kmz or GPS NMEA format Telemetry data is available at the transmitter in the form of a serial data stream. In order to transfer the data into an iPhone or iPad a dedicated iMSB FrSky Bluetooth Smart, also known as Bluetooth 4.0, module is to be used. This module is connected physically to the data port of your transmitter. Real time operation of iMSB FrSky is only compatible with FrSky S.Port enabled transmitter systems (X-Series receiver). Only S.Port based telemetry sensors are currently available. Further details related to hardware requirements can be found on the iMSB web site. But even if your transmitter is not yet ready for real-time logging, you can jump start exploring the power of iMSB FrSky with the built-in demo flight recordings. http://www.imsb.ch/terms-and-conditions.html ## Key features - Real-time telemetry data display - Flight session recording and playback - Customizable thematic views - Voice commands and announcements - Individual alarm thresholds - Flight statistics and analysis - Export flight log data ## Pricing and in-app purchases Base price: Free. **Subscriptions** | Subscription | Price | Period | | --- | --- | --- | | FrSky Bluetooth access | $6.49 | per year | ## Recent user reviews (3 of 3) All indexed reviews: https://appshunter.io/ios/app/imsb-frsky/id1118712180/reviews.md ### 2/5 — Problems on IPad Pro *2023-01-29* The setting button does not respond, also some of the view settings buttons don’t work correctly either. Seems ok on iPhone. ### 5/5 — Awesome App *2020-08-16* This is an amazing app. Coupled with an iPad and it just blows me away! ### 5/5 — iMSB *2018-06-14* Just wanted to let everyone know what a great app this is. You can configure several different displays any way you like to suit your needs. Works very will with FrSky sensor. Links up with my Taranis Q X7s with ease. I put my iPad on a try-pod and now have nice big displays with voice call outs. Flights can be recorded as well. The more time you spend with it the better You will like it. Just have it set up before you go fly. I had one or two questions for the developer and he was very helpful and quick to respond. ## Frequently asked questions about iMSB FrSky ### What is iMSB FrSky? iMSB FrSky is an advanced application for iPhone and iPad that displays and logs telemetry data from FrSky OpenTX based RC transmitter systems.

In release 3.6 we already introduced the Lua Sensor Scripting library allowing a script to be associated to a specific sensor value, evaluated on a regular basis during data logging. Lua scripting is a perfect tool for adapting functionality to user specific needs and perform complex data processing not available in the standard app. With this release we even go a step further and introduce the iMSB Lua Widget Scripting library. With this library user specific widgets can be programmed and attached to an iMSB display view. Widgets are essentially a graphic representation of a display element, such as a meter, used to display sensor values or any other graphic representation. A Lua Widget is attached to a display view the same way as any other pre-defined meter. Lua Widget scripts interoperate together with the Lua Sensor scripting library, to access sensor values and other attributes that need to be displayed in a Widget. The Widget library offers a great means to extend you display capabilities to suit you particular need by adding features not commonly available in the application. Please refer to the iMSB web site pages for further information and to access the programming reference guide. A couple of other features and enhancements are as well available for this new release. Features: • Added SM-Modellbau MicroVario to the available sensors list • Introduces the iMSB Lua Widget Scritpting library allowing developers to program user specific display view elements • Added a widget scripting editor and simulator to the display view layout configuration view • Added the possibility to import and store external imaged to be used with a lua widget script Improvements: • Added a filtering mechanism in the flight logs view.
