FlyTower F3 Instructions
Warning
Instructions for using
1, Please install ANT (must be DONE) before debugging or testing VTX（and OSD）, or lead to VTX not working properly.
2, please use proper tools to install FlyTower .It is easy to damage the PCB components by using sharp tools. (warning: Bear
in mind that screws do not install too tight between every layer, so as not to destroy the PCB and electronic components).
3, When you debug or test flight control Please remove all the propeller; Try not to test indoors, So as not to cause safety
accidents. Install the propeller before a test flight, please check again.
4, Please check and adjust ESC plate welding, thus brings all the losses and problems, or you should face the consequences.
5, Please do not fly your drone near the crowd, for all the losses from the crashed aircraft, you should face the consequences.
6, For your safety, please do not use more than 4s battery, Using more than 4s battery would cause safety risk, we will not
undertake any responsibility.
7, Before power on, please check the positive and negative pole again to make sure whether there is a short circuit .( you also
have to check that whether there is a short circuit between your motor cables and you drone’s body).
8, Please use original screws and fixings to install FlyTower.

How to use the onboard USB port updated
firmware in GUI on windows
To flash the firmware you have to enter the so called DFU mode. On Windows 10 I had to use a
tool called Zadig (download and start it) to be able to switch drivers for DFU mode to work. In
order to switch drivers you have to take the following steps.
Down: http://zadig.akeo.ie/

www.exuavrc.com
•Push BOOT button on the flight controller.
•Plug-in the USB cable (the red LED should not be as bright as normally).
•Fire up Zadig and hit “Options”and then “List All Devices”.
•From the list choose “STM32 BOOTLOADER”.
•Under “Driver”choose “WinUSB”on the right and hit “Reinstall Driver”.
•Close Zadig, disconnect the flight controller, close all Google Chrome instances.

VTX use and settings
1,VTX key switch Instructions (print on VTX on FC and VTX board has a small error),just follow this picture:
2, Channel switch: short press SK, CH1-CH8 in there group, the current channel lights flash 1HZ ，and short click to jump to
the next CH. For example, the current state of CH1, short press SK, CH1 flash. And then press SK, jump to CH2 flash, continue
to press SK, CH3 flash. This process to do the cycle of CH1-CH8 (4 lights show the 8 CH channels, detailed description of the
following table). 5 seconds later the setting will exit without touching SK.
3, Frequency group switch: long press 2 seconds SK, A-E where the band group slow flash 1HZ, and then click on the SK for
a long time, after the release will jump to the next group. For example, the current working state is A group CH1 status. Long
press SK two seconds and release the A slow flash 1HZ, and then long by two seconds SK release, jump to B slow flash 1HZ.
The second process is same as above. Do A-E polling, note here: (A-B-C-D to indicate that the E band, A-B 2 lights all
bright). Similarly, do not touch the SK, 5 seconds after the automatic exit settings. Follow up will launch 60 channel BC, CD,
AC, AD, BD channels, etc.
4, Power switch: fast short press SK two times, then A-E frequency group under the condition of full bright light and continue
to quick press twice at SK,, then began to switch power, the corresponding power is 25mW 200mW 500mW frequency light:
bright 1 is the minimum power, bright 2 is a medium power, the 3 is bright the maximum power.
