 1. Install first maple USB driver by running the batch file found in Arduino STM32 package folder ```..\hardware\Arduino_STM32\drivers\win\install_drivers.bat```
 1. Download the free STM32 flash loader demonstrator from [ST.com](http://www.st.com/en/development-tools/flasher-stm32.html) and using a USB-TTL device (like FTDI cable) flash the STM32duino bootloader available from Roger Clark's great STM32 site [here](https://github.com/rogerclarkmelbourne/STM32duino-bootloader/tree/master/STM32F1/binaries) .Use bootloader **generic_boot20_pa1.bin**

 Notes:
-- When you use multiSTM32_USB for the first time,the USB drivers are not recognized and port is not open/recognized(arduino IDE port selection is grey/unavailable). After this first time use, any subsequent update of the program, you'll have to select the correct serial port and  upload sketches normally in Arduino using USB port.

+- If using Banggood  multiSTM32_USB module, follow instructions from step1(USB drivers on your computer) and jump after, to step 3(most probably generic bootloader is installed on multi module and no need to be installed again).I don't have one for test so this is an educated guess.

 ## Binding
 For telemetry enabled modules, you should just let the remote autodetect the settings. Otherwise choose DSMX 22ms with 6ch or 7ch. To bind the model, keep the transmitter off, power on the Inductrix. Wait until it flashes fast and then power up the Tx and use Bind.
 
-## Tx Setup
-Remember that 100% on your transmitter using the MULTI-Module corresponds to 125% on the DSM receiver side.  On some functions sending 100% will confuse the model. Conversely 80% on your Tx is interpreted to be 100% at the model. Consider this when implementing the suggestions below.

 ### Throttle
 For Inductrix FPV you might need to adjust the lower end of throttle to be a higher than default, otherwise motors will be spinning on minimal throttle.  One way to do this is to set the throttle to 80% output (100% of DSM output) and then to enable the **Throttle Idle Trim Only** under the Model Setup menu.  See image below:
