This permits a lower latency in the commands. • Now regardless of whether the flight controller's governor is used or not, when the model blade length is selected in Wizard panel 10, the governor's Speed1/Speed2/Speed3 values are raised to the typical RPM values for the model size (low for large models high for small models) • In panel n°1 “General Instructions” of the Wizard, "SAB Goblin 580 Nitro" has been added to the model selection dropdown list • Added in panel 1 of the Wizard the item “Transmitter Mode” for a better support and statistic purpose • In panel 5, the "Tail Gain" signal slider changes to blue color if during subsequent tail setup it was decided not to use a radio channel to control tail gain but to select the "Is set in software" checkbox. This is because in this case it will be more obvious that the tail gain slider position in panel 5 and controlled by the transmitter, cannot modify the tail gain • Added three traffic lights in the title bar of Wizard panel 5 that indicate in real time whether the receiver and/or satellite 1 and/or satellite 2 are working or not working or whether the signal is intermittent • Increased in panel 12 of the Wizard and in Advanced the maximum value of “Pulses for rotations” from 20 to 25 (for the new DirectDrive motor bundled in RAW 420 with 21 pairs of magnets) • Added under “Help” menu the new files for Integration on FrSky transmitter using the new ETHOS OS (Tandem20 / 20S, Tandem18 / 18S, Horus X12S-ISRM, X10 / X10S Express) • Released a new updated version of the Brain2OpenTX.zip file (see ReleaseNotes.txt) • Released a new updated version of the Brain2Jeti.zip file (see ReleaseNotes.txt) • Revised Spektrum Integration • Revised Graupner Integration • Added for better diagnostic purpose the following purple ESC Events: 220 "ESC: Low voltage protection" For YGE, Scorpion, Kontronik, HobbyWingV5 221 "ESC: Over current protection" For YGE, Scorpion, Kontronik, HobbyWingV5 222 "ESC: Over temperature protection" For YGE, Scorpion, Kontronik, HobbyWingV5 223 "ESC: Input throttle is not at 0% position" For HobbyWingV5 224 "ESC: Motor locked protection" For HobbyWingV5 225 "ESC: Throttle Signal loss protection" For HobbyWingV5 226 "ESC: Abnormal input voltage" For HobbyWingV5 227 "ESC: ESC lack of one phase" For HobbyWingV5 • Many additions, changes and improvements in the data saved within the configuration files, Event files and recorded Logs files, and in the management of update server data so that we can do more in-depth analysis on the files received from users and offer better support and diagnosis and remote assistance • Revised French instructions • Some revision of icons, connections diagram, names, titles, labels, units and instructions • New version of “README_for_ESC_datas_log_and_telemetry.pdf” document • Improvements/optimization/compression/size reduction/speed up of the code

For now selectable only from the protocols drop-down menu in: ADVANCED => Common => Receiver • Added a power supply voltage check that prevents the firmware update process from starting if the voltage is too low. This is because by analyzing the external event memory of the Flight Control Units that came back with the processor ROM erased and/or altered, we have seen that in these returns the events "Voltage 4,3V" are always present • Added in the Firmware update progress windows the red phrase “Do not disconnect and do not remove power and do not close the program until the update process is finished !!!” • Added a new message box “No Firmware selected” that appear if in the Firmware selection no firmware was selected before click on “Upload Now” • Added the orange background that warns that the configuration of one of the Wizard panels has not been completed also in panels 9 (Tail Rotor Setup), 10 (Blades Size) and 13 (Flying Style) • Added in the Bluetooth configuration windows the phrase “Avoid using “special” characters for NAME but use only letters and numbers.” in order to eliminate the problems encountered by some users • Increased the minimum values for Speed 1, 2, 3 on the Governor page from 500rpm to 1000rpm following problems encountered by some users with some Speed set at 500rpm and with the model losing altitude too quickly • If "Min V to go" has been set to a number of Lipo Cells greater than 2, but the ESC telemetry is not working due to misconfiguration or miswiring, the throttle will not lock as when there is no active ESC telemetry reading the battery voltage. • Added in panel 14 (Final checks) an explanation of elevator swashplate movements • Fixed the Fail Safe behavior with R3XXXXSB / R2XXXXSB receivers (FHSS) when telemetry is used using S.Bus2 • F.Port & F.Port2: eliminated occasional servo movements during Logs download • Some revision of names, titles, labels, units, instructions & menu order (English and Italian) • New version of “README_for_ESC_datas_log_and_telemetry.pdf” document • Improvements/optimization/compression/size reduction/speed up of the code

• Added to the 11 Jeti telemetry transmitted values selected in the “Parameter Setup” tab of DIAGNOSTIC, also the “Log Parameter 12” value “Global Vibrations”. If an ESC is selected in “Telemetry Input” of panel 12 of the Wizard, are also transmitted “ESC Battery Voltage”, “ESC Battery Current”, “ESC Battery Used”, “ESC Battery Ripple”, “ESC Power Output”, “ESC LS RPM”, “ESC Temperature 1 (°C & °F)” values. If Hobbywing or Jive Pro or YGE are selected also “ESC Temperature 2 (°C & °F)” are transmitted. If Jive Pro or YGE are selected also “ESC BEC Current” is transmitted. A New AUTO Discover is not required, but all new parameters must be Added in “New Displayed Telemetry” if you want to see it • Added in the File menu the “Reset Logs to default” command • With Tandem Rotor models, by giving elevator commands the pitch increase of one rotor is greater than the pitch reduction of the other rotor to achieve a behavior of Tandem Rotors models more similar to that of single rotor models • Rewritten, simplified and reduced size of Firmware unifying some similar routines used for S.Port+S.Bus, F.Port, F.Port2 • If FrSky Neuron ESC’s telemetry signal is connected to the S.Port bus via an “Y” cable the ESC telemetry is recognized and can be recorded in Flight Controller logs • Added to the OpenTX the “PowerOut” pwm value (0-100%) with the sensor name “1000” (like for global vibrations, there are no predefined sensor for this kind of value in actual OpenTX versions) • Added the Event “Voltage > 8V4” as a warning that the receiver and/or servos may be damaged at such supply voltages, and that the BEC regulator may have failed • Added the Event “Flight Count increased” to better understand if that Event group is related to a real flight or to a bench test / ground test. Note: the “Flight Count” value in COUNTER section may not correspond to the number of Recorded Logs due to possible bench logging • Now in all “Integrations” “Pitch Out Max:” is displayed correctly also if “Reversed Pitch” is selected • Now using OpenTX S.Port + S.Bus protocol and connections, no more “sensor lost” message happen for VFAS sensor • Restored the filtering of the RPM signal used by the Governor to the highest filtering values used prior to the FW versions 3.4.013 because of problems with some ESCs (Castle Creation) with high noise on RPM wires • Starting with firmware 3.4.XXX the Spektrum Binding via Software and/or via Hardware does not work with SRXL2 receivers and the on-board bind button of the SRXL2 receivers must be used. Fixed • Now also with the F.Port2 protocol the secondary receiver connected via “S.Bus In” to the main receiver is correctly working • Values of Exponential’s that cause a slight change in the output values now work only for Pitch channel and not for all the other channels • Now if the unit still has the factory firmware, the configuration software won't start if you don't update the FW to a valid version, as explained in the instructions the units must not be configured and must not fly with factory firmware • Now the parameter selection dropdowns of the Windows configurator are opened by clicking in any area of the dropdown instead of the small button on the right as before • In panel n°1 “General Instructions” of the Wizard, “RadioMaster" has been added to the transmitter drop-down list and "Oxy 5 Nitro" has been added to the model selection list and at the request of some users "Zigsaw AYA" has been added in the blade’s selection dropdown • In panel n°3 “Receiver Selection” of the Wizard, in the Multiprotocol icon and lateral instructions the Spektrum SRXL2 protocol has been moved to the first position so that it can be more easily and quickly viewed by those who often select by mistake the Spektrum SRXL protocol used only by 4649T receivers [MORE...]
