Using Your New HACKED FlySky GT3B Radio

Getting Started:

The Hacked Flysky GT3B is a very powerful machine and quite simple to use. However, the GT3B comes with a very limited LCD which makes it not very user intuitive upon first power up. But, the user friendliness changes quite quickly once the menu layout and abbreviations are know. Therefore, this manual was written to make the learning curve a lot easier to travel on.

Let’s begin with a quick introduction to the new firmware. Its original purpose was to fix all the bugs in the factory firmware, functions such as limited trim and unfunctional expo. However, it’s grown to add a lot more functionality to the radio which puts it on the high end of the spectrum at a budget cost. To begin with, it doesn’t lose any of its original functions, it still has model memory, trims, expo, epa, dual rates, ABS, etc. Also, there is a brand new set of features that adjusts the radios properties. This includes how long the backlight stays on, an inactivity alarm, adjustable low power alarm, etc. Although these features are cool, it gets a lot better. There is a new Key Mapping menu and basically what it does is it lets the user select a switch or button that’s on the radio and program it to control one of the radios functions. Some of these functions are adjusting auxiliary channels, trims, expo, mixes, dual rates, and a lot more. The mapping menu is very powerful and has a lot of options to how the switch will act and all these options are explained in full later on. Another important menu is the mixing menu, which has Dual ESC and 4WS mixing. It also contains Multi-Position, which basically what it allows the user todo, is allow up to 8 positions on a channel to be selected in ANY order. These positions are cycled through with a switch or a button. A switch lets you cycle fwd/bck through the positions or a button is fwd only. There are also a lot of other features that will be mentioned later on.

All these features were strategically grouped to give it the most user friendly experience possible but with the limited LCD it’s not very intuitive on first power up. All the core features are easy to edit and nothing too complex, it’s just the new advance features which are hidden from plain view. Therefore, it’s highly suggestible this entire manual is read to obtain a full understanding. Now is the time to get a pot of coffee, 6 pack of energy drinks, caffine drinks, or something to stay attentive. Getting to know your radio:

14. 15. Navigation- 16. Navigation is simple on the Hacked Flysky GT3B.  Enter Wheel o 3 Functions: ENTER, ENTER-long, and ROTATE . ENTER  Pressed and let off quickly. It main purpose is to navigate across different menus. o So going from home screen, to main menu, to key mapping menu, to etc. . ENTER-long  Pressed and held for longer than 1 second. Its main purpose is to access the new advance menu’s and to exit from a sub menu. . ROTATE  Rotate the wheel clockwise or counter clockwise. Its main purpose is to scroll through menus or edit a menu’s value.  END button o Pressing the END button will exit from the current menu and bring up the main menu. If pressed on the main menu it’ll go to the home screen. o Pressing the END button will save the current setting  BACK button o Pressing the BACK button will exit from the current menu and bring up the home screen. 17. 18. Home Screen- 19. 20. The home screen simply displays current statistics about the radio. The 3 stats that are always there is the Model Name/number, the radios battery pack voltage, and the lap counter #. All are fairly self explanatory, however they are mentioned throughout the manual for further understanding, ROTATE the enter wheel to select the stat you wish to view. The Home screen also displays the new value of a function if a switch is activated. Once any button or key is pressed the new value will be shown on the screen for 5 seconds or until another button is pressed; once the value disappears it is saved to memory. Also, while the value is displayed you can use the enter wheel (ROTATE) to quickly change the values. 21. 22. Main Menu- 23. 24. The main menu is composed of 14 sub menus, 8 of these submenus are the basic/standard functions while the other 6 are the new, more advance functions. The most complex of these is the Key mapping menu, so it’ll be covered last. DON’T skip ahead because the key mapping menu use’s everything in the other menu’s. 25. 26. Model- 27. This menu selects which model to use and/or edit  Select it by Highlighting MODEL, then press ENTER  ROTATE the enter wheel to display the different model

o Models 0-9 are displayed with no arrow

o Models 10-13 are displayed with a right arrow

 Select the model by pressing ENTER

o This will load the new settings and return to the HOME screen

28. Save As- 29. This is one of those hidden menu’s that gives new features. The Save As menu allows the current model to be copied to a new model. This is helpful because if playing with new settings it allows a copy of the current model to be made, so settings can be reverted back to it if they get messed it up  Select it by highlighting MODEL, then press ENTER-long (press and hold for at least a second) o This will make MODEL blink  ROTATE the enter wheel to choose the model to copy settings to  Press ENTER or BACK to save/copy it and exit the menu 30. 31. Name- 32. This menu allows the current model’s 3 digit name to be changed  Select it by Highlighting NAME, then press ENTER o This will make the firs digit of the model name blink  ROTATE the enter wheel to change the digit o A-Z and 0-9 are the possible digits, no lowercase and no punctuation  Press ENTER to select the new digit o The 2nd digit should now be blinking  Repeat steps above edit all 3 digits. o Once all 3 digits have been selected the first one should be blinking, every press of ENTER will change digits  Once done editing the NAME, press BACK or END to save the NAME and exit the menu 33. Model Reset- 34. This menu resets the model to default settings  To reset model, highlight NAME  Then press ENTER-long o This will reset model and leave you in the main menu 35. Reverse- 36. This menu will reverse a channels output. Many esc’s will require the throttle channel(s) to be reversed in order to calibrate. Also the steering channels are often reversed dependent if the user is right or left handed. Reverse is offered for all channels  To enter this menu, highlight REV, then press ENTER  ROTATE the enter wheel to choose a channel, press ENTER to select it  ROTATE the enter wheel to choose desired setting, press ENTER to select o NOR = NORmal o REV = REVerse  Choose another channel to edit or press BACK/END/ENTER-long to exit menu 37. 38. End Point Adjustments (EPA)- 39. This menu allows the EPA’s on any channel to be adjusted, EPA’s limit the throw of a servo or other devices. EPA’s are often used where there is Mechanical Linkages: Dig transmissions, Multi speed Transmissions, throttle servos, steering servo’s etc. Its main purpose is to make sure that the servo doesn’t hit a physical stop ad burn itself up trying to push it. 40. 41. The EPA menu has a cool built in feature; once a channel is selected it will go to full throw so the channel can actively be adjusted. However, it is recommended to have the RC car powered down before entering the menu. While powered down enter menu and set EPA’s to 0 for the channels you plan on adjusting. Then power up model and slowly adjust epa’s to where they need to be set. 42.  To enter this menu, highlight E.POINT, then press ENTER  ROTATE the enter wheel to choose a channel, press ENTER to select it  Adjust EPA’s o Use ROTATE to change value o There are left and right EPA’s o Turn the steering wheel left or right to select which side to adjust . There is a arrow above the digits, this represents which direction . The Throttle Channel requires the trigger to be moved, not st wheel  Press ENTER to save setting, choose another channel or exit with BACK or END 43.

46. Trim & Subtrim- 47. Trim is only selectable for CH 1 and CH 2. This is because it should ideally just be used for quick corrections then moved to subtrim later on. The reason for this is very technical, so it’ll be left out. However, the sub trim menu allows adjustment on any channel. Basically what these settings do is adjust the center point of the channel; they just have different methods of doing so.  To select one of these menu’s, Highlight TRIM o Press ENTER for the trim menu o Press ENTER-long for the sub-trim menu  ROTATE the enter wheel to choose a channel, press ENTER to select it  ROTATE the enter wheel to choose desired setting, press ENTER to select  Choose another channel to edit or press BACK/END/ENTER-long to exit menu 48. 49. Exponentials- 50. Exponentials, also known as EXPO, affect the channel output; they change it from a linear output, to one with a curve. Their purpose is to decrease throttle sensitivity on the low end or the high end.  To enter this menu, Highlight EXP, then press ENTER  ROTATE the enter wheel to choose a channel, press ENTER to select it  ROTATE the enter wheel to choose desired setting, press ENTER to select o CH 2 has left/right expo’s indicated by arrow above digits. o Use the trigger to change between the two  Choose another channel to edit or press BACK/END/ENTER-long to exit menu 51. 52.

53. Here’s a graphic of expo curves. Refer to Stick Movement as Steering wheel or trigger movement

57. 58. Dual Rates- 59. Dual rates on the GT3B act as Dual Rates, but the way they’re put to use isn’t normal (at least to me). Anyways, basically Dual Rates are another form of epa that makes your steering or throttle movements less sensitive. This is because, say at 50% dual rates, the full throw of the trigger or steering wheel only controls the initial 50%. Normally these are use full because a switch or a button can choose between two different rates. So you can quickly change the sensitivity of the channel. This is still possible with a high step rate, but not as customizable as a true dual rate switch.  To enter this menu, Highlight D/R, then press ENTER  ROTATE the enter wheel to choose a channel, press ENTER to select it  ROTATE the enter wheel to choose desired setting, press ENTER to select o CH 2 has left/right D/R’s indicated by arrow above digits. o Use the trigger to change between the two  Choose another channel to edit or press BACK/END/ENTER-long to exit menu 60. 61. Channel Speed- 62. Channel Speed basically makes a fast servo (or other device) a slow servo. Its mostly helpful for throttle channels. For electric it slows down how fast the esc try’s to accelerate or brake a motor. This is good for traction reasons and possibly motor life. Another scenario its good for is nitro engines, it’ll put less strain on the engine by not allowing a very rapid change in fuel.  To enter this menu, Highlight D/R, then press ENTER-long o D/R should be blinking  ROTATE the enter wheel to choose a channel, press ENTER to select it o Ch 1 and 2 have arrows, which is selectable by moving st wheel/trigger o Left arrow . Ch-1 Turn Speed . Ch-2 Throttle Speed o Right arrow . Ch-1 Return speed . Ch-2 (on/Off) for throttle speed on forward only  Select speed, press ENTER o 1% has more than a 4 second delay from end to end o 100% = no delay  Choose another channel to edit or press BACK/END/ENTER-long to exit menu 63. 64. ABS- 65. ABS will pulse the brakes instead of providing a solid brake signal. There’s 4 options: Off, slow, normal, and fast.

Key mapping is where all the magic happens for the auxiliary channels on the GT3B. Just as it sounds, you can actually map the keys to do any function you want and have it act however you want…if your want exceeds what the firmware allows, then you can request that it be added. Anyways let’s begin;

102. To enter the key mapping menu  Scroll over to REV, so its highlighted

 Press and hold Enter for about 1 second  REV should be Flashing

103. Navigating the key mapping menu  There should be a far left digit blinking, this represents which key

o 1 = Ch1/ST Trim (Both Buttons)

o 2 = Ch2/TH Trim (Both Buttons)

o 3 = Ch3 Trim (All Positions)

o D = D/R Switch (All Positions)

o C = Ch3 Button

o B = Back Button

o E = End Button

o 1  = Left ST Trim Button

o 1  = Right ST Trim Button

o 2  = Forward TH Trim Button

o 2  = Back TH Trim Button

o 3  = Left CH3 Position (acts as button)

o 3  = Right CH3 Position (acts as button)

o d  = Left D/R Position (acts as Button)

o d  = Right D/R Position (acts as button)

. For  ,  you will see arrows above main display

. In order for the arrows to display, you must have the main key(s) set to off

 Scroll to the key(s) you wish to map/edit

o Press enter

 Modify first setting

o Press enter

 Modify second setting o Press enter

 Etc,

o You can exit and save your setting at any time by pressing and holding Enter (for ~1 sec)

106. Modifying Settings for Trims, and D/R Switch 107. (These go in order, with what you’ll see on your screen)

108. Function: (This selects what you want the switch to control)

 Off

o It turns this switch off, so it does nothing…it will activate it so it can be set as a individual key.

 TR1, TR2

o Assigns the switch to modify the trim settings of Ch1 or Ch2. Other Ch’s aren’t currently supported

 DRS, DRF, DRB

o Assigns the switch to control the Dual Rate menu for the Steering, Forward control, and backward control

 EXS, EXF, EXB

o Assigns the switch to control expo for the steering, forward control, or backward control

 CH3, CH4, CH…8

o Assigns the Switch to control a auxiliary channel

 ST1, ST2, ST…8

o Assigns the switch to control the sub trim or a give channel

 4WS

o Assigns the Switch to control the 4 wheel steering mix, which is activated via the mixing menu (4WS mix)

 SST

o Assigns the switch to control Steering Speed Turn

 SSR

o Assigns the switch to control Steering Speed Return

109. Buttons: % (How you want your switch to behave)

 MOM

o MOMentary When switch/button is held left/right it will take you to the endpoints of the channel. When nothing is pressed, channel is at center

 NOL

o No Long Keys- A long press is the same as a short press, so it simply moves the channel according to step rate and other settings.

 RPT

o RePeaT-This turns auto repeat on, so if you hold the button, it will keep increasing the function its controlling

 RES

o RESet- A long click will return the function to center or reset value

 END

o END- A long click will bring the function to its endpoints…in relation to direction of click

112. STEP: %V

 This is real simple, just select the % you want your function to move, for each click of your switch. It will +/- this percentage/value o Note: You will not see this menu if you selected MOM from the Buttons menu, or MPO from the Function Menu

113. REVERSE: V

 NOR

o NORmal- This will leave your switches working in their normal way as indicated on the radio

 REV

o REVerse-This will swap your left/right keys/direction. So they operate backwards

114. Opposite Reset: V blinking (Will not show up if Button is set as MOM

 N00

o No Change

 ORS

o If clicked in the opposite direction of you previous click, as if you were to decrease value. It will reset the function to center, or the reset value

115. Previous Value: % blinking (Only will show if Buttons is MOM, or function is MPO)
