Fällt euch das gar nicht auf? ### 1/5 — Needs Work! *2022-11-19* So you spend the extra hard earned $$$ to buy Bluetooth functionality, download the App, and when you go to use it, it just doesn’t work. Very very frustrating. I was able to connect to the device, but get dropped within 1 min. Please fix the Alert (G/cannot communicate with unit) and the dropouts. People expect for these expensive toys to work!! BTW, both Brain2HD and iKon2HD behave the same. They have the same issues, so if you think buying an iKon will yield better results, been there done that!! I guess for now it’s back to using a PC only!! Hopefully these defects get fixed since we did pay for them! ### 2/5 — Nur bedingt brauchbar… *2022-09-27, version 3.4.059* Inbetriebnahme des Brain, per App, war nicht möglich. Grund dafür, die Firmware musste aktualisiert werden, was über die App aber nicht funktionierte. Ansonsten, kein vernünftiges Arbeiten möglich, da die Software ständig abstürzt. Dafür Geld zu verlangen ist eine Frechheit! Bin sehr enttäuscht… ### 1/5 — Never works *2022-06-14* I have it on a Goblin 380 and it’s pretty much useless. I always have to go to computer to get it to make changes. NTSB dream come true ### 1/5 — Gut gedacht, funktioniert aber leider nur sehr schlecht… *2022-06-12, version 3.4.059* Abstürze und Freezes ohne Ende, egal ob auf dem iPhone oder iPad, das neueste Betriebssystem ist auch immer installiert… und das bei diesem Preis. Eine Lösung für das Problem wäre wünschenswert. ### 1/5 — Complete waste of money! *2022-05-26* I had high hopes for this, having bought the Bluetooth module for the Brain unit. But his app is complete garbage! It locks up and crashes every time I try to use it. I want my money back for the app, but I guess I won’t get it. And the money for the Bluetooth was a waste too. ### 1/5 — Freezes, crashes. Useless *2022-02-16, version 3.4.012* Are these people still trading? not a good idea to buy their products if they are unable to support us. Nobody gives a toss anymore, just take the money and run. Shame because it looked like it had potential. Brain Hd ### 1/5 — Why is this app so bad!? *2022-02-03* I have a brand new IPhone 13 pro and this app freezes, shuts down and will randomly close for no reason. After a half hour trying to use it, I went to the site to get the computer version. Guess what… it’s only for windows! No mac version and it’s 2022!? I had to install boot camp on my Mac to use 1 app, annoying. Dear developers of this app, fix the problems or stop charging $10 for something that works 50% of the time. ### 1/5 — Crashes a lot *2021-11-14, version 3.4.012* Crashes *constantly* and is very slow. Almost impossible to use. Android version didn’t have this problem. Please fix the major bugs and I will update my review! ### 5/5 — Works great! *2021-09-30, version 3.4.012* I installed this app on my iPhone 6s Plus running the current iOS. I’m not experiencing any of the problems that other people are having. I actually think the iOS app works better then the PC version. Great job guys! I also bought the diagnostic app as well! BTW if you’re having a problem getting the app to pair with your iPhone go into settings and let Bluetooth find it. It will ask for a pin. Type 0000 (4 zeroes) and it will pair! ## Frequently asked questions about Brain / iKon / Xbar / TracX ### What does this app do?

In this way, the optimal operating parameters for Futaba's new UR servos (center pulse 200us 1150Hz) and/or Theta servos (center pulse 300us 1000Hz) can be configured in ADVANCED, section 4 ‘Servos’ • Now by activating (or deactivating) the H-4X 4-servo swashplate, it is no longer necessary to reboot the flight controllers to activate the correct servo 0 operation, but the operation is adjusted in real time upon selection • For control units that still use the older model gyro sensor, we have deactivated the controls that were added in the latest firmware version for the new sensors because some users report difficulties when switching on the older control units for the first time • When using motors coaxial to the main shaft, in the vibration graphs, the reference labels ‘Motor’ and ‘Head’ are no longer superimposed on each other so that it is clearer that high vibrations can be generated by both • Added some functions in the firmware for diagnostic purposes to facilitate and speed up diagnosis and technical support to users who request it • Corrected, improved, and made some paragraphs of the instructions clearer and more complete • Shortened some of the names of loggable parameters by eliminating blank spaces and also eliminating the gaps between one checkbox and the next so that they are all visible even with reduced screens and resolutions • Revised French instructions • Improvements / optimization / compression / size reduction / code speedup ### 3.4.201 — 2025-03-04 • ESC Events: If errors are transmitted from the ESC telemetry while the flight control unit is still initializing, they are saved and recorded in the flight control unit's EVENTS immediately after initialization is completed    • The ‘Min V to go’ function now holds the motor in place even when YGE ESCs are used, which unlike all other ESCs, when programmed to work with Futaba brings the minimum value of throttle pulses to switch off the motor below 1000uS (to 950uS)    • JR X-Bus Protocol A: handle unforeseen situations where users incorrectly program transmitters with a throttle signal below -5% and/or above +105%    • The “Configure Bluetooth module” function to initialize and change PIN and NAME of Bluetooth modules now works with more model of Bluetooth modules (the total time the two LEDs both stays lit indicating the sending of the various initialization commands to BT module is now ~12 seconds)    • Added QOS for FrSky receivers that can set the serial output connected to CH3 to “SBUS out” mode (EG: TD-RXX)    • Now with Graupner ‘Basic telemetry’ (RPM for Nitro, Gasser, Turbine models) is also simulated with ‘HoTT Sensor Kind’ set to ESC (that is the default sensor kind) in case ELEC and GEN are already used by external sensors connected to the telemetry bus    • Improved in DIAGNOSTIC the resolution of vertical scale of VSAT parameter (renamed to “SAT Voltage”)    • Following the appearance of 12V servos on the market, event 161 (Servo Voltage greater than...) now occurs when the voltage exceeds 13V.    • In COUNTERS added ‘One Way Bearing’ to the list of components whose time-of-use is to be calculated    • For receivers that can be programmed by the transmitters to use different protocols (EG: F.Port/F.Bus, Crossfire, etc.) the QOS values (Fades, Frame losses, Holds, Frame Rate, etc.) are reset to zero even when changing communication protocols without cycling the power supply.    • Added inside “Brain2OpenTX-EdgeTX.zip” the new folder “_HOTT_MULTI”    • New version of "Brain2_FwdPrg.lua" (inside the folder “_SRXL2_MULTI” in the “Brain2OpenTX-EdgeTX.zip”)    • Updated inside “Brain2OpenTX-EdgeTX.zip” the configuration example file “TX16S_Brain2.yml” for working also with Nitro / Gasser / Turbine models    • New version of “Brain2OpenTX-EdgeTX.zip”    • New version of “Brain2crossfire.zip”    • New version of “Ethos_Integration.zip”    • New version of “Brain2Jeti.zip”    • Updated Spektrum Integration    • Updated Graupner Integration    • New version of the embedded document “README_for_ESC_datas_log_and_telemetry.pdf”    • New version of the embedded document “README_for_OpenTX_EdgeTX_integration_for_BRAIN.pdf”    • Added some instructions, changed some instructions, some tooltip, some labels in the app and also in the Integrations and also in the Events to be clearer    • Revised French instructions    • Improvements / optimization / compression / size reduction / code speedup ### 3.4.149 — 2023-12-20 • Added to the Micro Brain2 FCU the management of the B-Aux3 channel on the CH4 connector to be able to control buzzer activation, retractable landing gear, lights, winch, smoke, etc. etc. via PWM signal • Added handling of the new SKY telemetry parameter introduced by Spektrum with the November 21 AirWare update • Introduced minor changes in the parameters of the "BEGINNER" flight style so that it can also be used satisfactorily in scale models, and added some information about scale models in the instructions • Until panels 1 through 6 of the Wizard are completed, the servo outputs remain off so that panels prior to 7 and especially panel 5 can be configured correctly without being affected by servo movements • In model with tail motor, to facilitate the tail setup minimum, zero and maximum, now when check mode is active (EG in panel 9 of the Wizard) tail motor can run also if main throttle is at zero • Improved in software matching of the actual manageable and working functions of the old Brain and Micro Brain flight controllers • Added “Cancel” to the “change language” confirmation message • Added and improved some functions used to be able to provide a better remote assistance • Changed some instructions, some tooltip, some labels in the app and also in the Integrations to be clearer • Revised French instructions • New version of the document “README_for_ESC_datas_log_and_telemetry.pdf” (+ELRS) • New version of the document “README_for_OpenTX_EdgeTX_integration_for_BRAIN.pdf” (+TBS) • New version of the document “README_for_Spektrum_Integration.pdf” document • Improvements / optimization / compression / size reduction / code speedup ### 3.4.139 — 2023-10-27 • Added the telemetry decodify of OMP ESC • Implemented Forward Programming Integration for those who have Spektrum telemetry receivers on their models but have switched to using transmitters with OpenTX / EdgeTX operating systems and Multi Module Radio frequency. An LUA app will be released later • Corrected the calculation of vibration frequencies with some production batches • Added in apps and integrations to the list of adjustable parameters via Dials "TAIL: Proportional Gain" to simplify life to users who have set tail gain to "Is set in software." • Modified the window for Bluetooth Configuration so that it can also contain longer texts (French) • Changed some labels in the app and also in the Integrations to be clearer (EG: “VSpeed” to “Vertical Speed”) • Lowered the automatic RPM drop when mAh Max Usage is exceeded from -18,75% to -12,5% for low main rotor speed flyer • When mAh Max Usage is set at maximum (7000mAh) the function is totally disabled • Raised the “Min V to Go” threshold from 3.82V to 3.88V • Added in page 1 of the Wizard the “Radix” brand in the “Main Blades” and “Tail Blades” lists • Added in page 1 of the Wizard the “AGF B53BHP-V2” servo in the “Cyclic Servo” list • Added in page 1 of the Wizard the “HiTec HSG-8315BH” servo in the “Tail Servo” list • Added in page 1 of the Wizard the “FullPower” brand in the “Power Supply Type” list • Added in page 1 of the Wizard the “FlySky” brand in the “Transmitter Brand” list • Made visible and operable in the telemetry selection dropdown the "DISABLED" item that was already displayed with the old flight controllers now also with the new flight controllers • Although the confirmation prompt "Are you sure Y/N" is present, some users still reset by accident. For this reason moved to the bottom of the command list in the File menu the command "Reset to factory defaults ..." • More diagnostic information saved in the configuration files • Used and updated version of the Compiler • Changed some instructions, some tooltip, some labels in the app and also in the Integrations to be clearer • Revised French instructions • New version of the document “README_for_OpenTX_EdgeTX_integration_for_BRAIN.pdf” (+TBS) • New version of the document “README_for_ESC_datas_log_and_telemetry.pdf” (+ELRS) • New version of the document “README_for_Spektrum_Integration.pdf” document • Improvements / optimization / compression / size reduction / code speedup ### 3.4.127 — 2023-08-18 • Crossfire channel reception up to 16CH (with ELRS and Packet Rate 333Hz Full) • New Brain2Crossfire.zip version of Crossfire Integration package (Release Notes inside) that now other than TBS work also with ELRS External Module. Note: this version of the LUA app work only starting from this new firmware and for both TBS and ELRS external modules • Added the new "High Vibrations" Event that is triggered if Global Vibrations continuously exceed 200% for at least 4 seconds. Even if the Global Vibrations continue to remain above 200% the event is not repeated until 2 minutes have elapsed • In panel 3 updated the F.Port protocol icon • In panel 12 of the Wizard moved the section "Sensor Input:" right after the first section "Setup Throttle Out & RPM reading:" since the two sections are related to each other • Swap the positions of panels 11 and 13 of the Wizard with each other • Clarified, completed, improved and updated some instructions and some message boxes • Changed some labels in the app and also in the Integrations to be clearer (EG: “VSpeed” to “Vertical Speed”) • Revised French instructions • New version of the document “README_for_OpenTX_EdgeTX_integration_for_BRAIN.pdf” (+TBS) • New version of the document “README_for_ESC_datas_log_and_telemetry.pdf” (+ELRS) • Improvements / optimization / compression / size reduction / code speedup ## Apps similar to Brain / iKon / Xbar / TracX | App | Rating | Price | Category | | --- | --- | --- | --- | | [Barcolana](https://appshunter.io/ios/app/barcolana/id1041306588) | — | Free | Entertainment | | [Emotional support pet](https://appshunter.io/ios/app/emotional-support-pet/id6496065171) | 4.0 (4) | Free | Entertainment | | [RC Flight and Battery Log](https://appshunter.io/ios/app/rc-flight-and-battery-log/id1175533974) | 4.8 (182) | $4.99 | Entertainment | | [102.7 The Fanatic](https://appshunter.io/ios/app/1027-the-fanatic/id526821497) | 4.0 (6) | Free | Entertainment | | [Inspo Hair](https://appshunter.io/ios/app/inspo-hair/id6740243681) | 5.0 (7) | Free | Entertainment | | [Soul Karma Test: Good or Bad?](https://appshunter.io/ios/app/soul-karma-test-good-or-bad/id6743445963) | — | Free | Entertainment | ## Related topics [tracx](https://appshunter.io/ios/topics/tracx) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
