Flycolor X-Tower 2 - Multi-Rotor Flight Control System Manual

Safety information

Any Improper operation may cause personal injury damage to the product and related equipments. This high power system for RC model can be dangerous, we strongly recommend reading the user manual carefully and completely. We will not assume any responsibility for any losses caused by unauthorized modifications to our product. We have the right to change the design, appearance, performance and usage requirements of the product without notice.

Main features

ESC

• MCU:STM32F051, ARM 32-bit Cortex MCU, frequency up to 48 MHZ
• MOSFET with high performance and low Rds, not afraid of large current, more suitable for rapid flight.
• ESC firmware: Flycolor_X_Cross_BL_32
• Two layers tower structure between 4in1 ESC and FC,using cable for quick connection, using silicone vibration absorber for supporting, reducing the effect of vibration on Flight Control
• Damped light does regenerative braking, causing very fast motor retardation, and inherently also does active freewheeling
• The code supports regular 1-2ms pulse width input, as well as Oneshot125, Oneshot42 and Multishot
• All Dshot and Proshot signals are supported

Flight Control

• FC firmware: STM32F7X2 (Config. :FLYCOLORF7)
• FC board: FLYCOLORF7
• MCU:STM32F722
• Gyro MPU-6000 SPI
• Bluetooth: FC_Bluetooth
• USB: Type C
• Supports SBUS,SPEKTRUM1024/2048 etc. remote control / receiving mode
• FC integrated 3.3V,5V, 12V for receiver, VTX, camera, buzzer, LED and other peripheral devices
• 4-way led port, independent 5V BEC power supply, making the power supply more safe and reliable
• Supports Betaflight Configurator to adjust the LED color
• Install holes: 30.5x30.5mm, M3

Specifications

Part list / Install Dimensions and Diagram

Connect diagram of ESC and FC

ESC

• All soldering tasks require good soldering technique, short circuit between components or wires should be avoided at any time.
• Please ensure that all wires and connecting parts are well insulated to avoid product damage due to short circuit.
• Please double-check the polarity is correct before power up.

F.C

*5V: 5V output here after inserting USB, (it is convenient to debug the receiver without power on); the other 5V / 10V ports need battery power before voltage output.

Load firmware for FC

You need to use DFU mode to recover firmware for Flight control, and need a software tool called Zadig to replace the driver for you F.C when you load firmware at the first time.

(Notice: If you've run the above steps before, then you don't need to repeat, starting directly from the 6th step)

Attentions

• Please don't load any other firmware or config. for FC
• The Bluetooth port is fixed as MSP of UART4;
• SBUS and Spektrum receivers are applicable to all UART ports
  (except UART4, which is fixed to Bluetooth).
  It is required to manually turn on the "Serial RX" of the required UART port;
• UART6 is recommended for telemetry port,
  which can be directly connected with ESC / flight control connecting wire;
• Flight control should be far away from all magnetic materials
• If there is any deviation between the detected voltage/current with actual situation, you can adjust the scale value in the Betaflight-Power&Battery
• 5V,10Vsupply is for low-current use only(5V 3A MAX, 10V 1.5mA MAX)
• ESCs use BLHeli-32 firmware, please don't load any other firmware except "Flycolor_X_Cross_BL_32"
• User needs to calibrate the throttle range when starting to use a new ESC or another transmitter
  When the input signal is Dshot, throttle calibration is disabled
• Observe polarity at all times. Check and double check before applying power
• Power off before unplugging, plugging in or making any connections
• Please do not exceed the current & voltage range of ESC
• Please ensure that all wires and connecting parts are well insulated to avoid product damage due to short circuit
• Never use this product in harsh environments such as humidity, high temperature, and so on to avoid product damage
• Please contact Flycolor sales or technical support for more information.
