Transmitter Setup /Calibration
DO NOT SKIP ANY STEP - the very rst thing you must
do for your rst MultiWiicopter.com pnp PARIS v4r6 board
is Calibrate the Tx - Ground yourself (static safety measure)
then connect the Receiver (Rx) to the PARIS, connect the
PARIS to your FTDI-USB - USB supplies limited 5v power
(after installing the FTDI drivers,java - see wiki links - do a cold
restart) and then turn on your Transmitter (Tx) and set Mode
2 - ACRO(airplane) & PPM(not PCM). Do NOT connect
anything else to the PARIS ! - then Launch the matching
2.2p->2.2p Config or 2.2p->2.2p Application/program on
your PC or Mac (requires java) press com/start (see page 2 for
full details) and whilst looking at your PC screen - you will see
that changes made on the Tx are sent to the PARIS via your Rx
- and the critical uSEC readings such as 1095/1500mid/1905
can be set. PARIS is a 5v digital interface and the software
running invisibly inside requires very specic digital PWM
uSEC numbers to come out
of your Transmitter - to hover
100% level, to arm, to disarm
etc. So this may seem a bit
weird but you will be using/
pressing buttons on your
Tx whilst your eyes are
looking at your PC or Mac.
So USING TRAV ADJ (JR) - END
POINTMENU (futaba) move
each stick to the low position
and set end point to 1095;
then move each stick/switch to
the high position and set 1905.
Do this for all sticks and switches. Then, move all sticks to
the centre - set all Tx trims to neutral - Now use SUB TRIM
MENU on your Tx to set all mid points of 1500. Live links
to downloads on the Wiki page at Multiwiicopter.com If
you are stuck - stay calm - DO NOT LOAD Default/
new code - this will wipe all the code installed/tested in
your board, disable the sensors and cause you real problems -
relax - power the board with 5v (USB hiOut) and read these
instructions fully - slowly
Orientation - the light blue bars (above) MUST move
in the same direction as the stick you are moving
- If they do not then REVERSE that Ch in your Tx. So if you
move the throttle stick up - then the blue Throotle bar should
move up. If you move your rudder right then the YAW bar
should move right. - then - ESC THROTTLE LEARNING
- NOW go back and do/re-do the ESC calibration
one by one for each esc - THORTTLE-LEARNING (an
ESC function - nothing to do with Multiwiisoftware) This is
especially important if reusing KK ESCs or ESCs used in other
copter controllers.
PARIS v4 power - Choices
PARIS v4.o boards offer a split DC bus to prevent noise from
entering the CPU and sensor section if you wish using the
noise bridge in the open position. This noise bridge is supplied
soldered closed (if you
have a soldering iron
you can open the bridge
- if you don’t have a
soldering iron the board
is still PNP ready) So
you can choose how
to build your system
depending on the quality of your electronics - There are 4
ways to power a multicopter PARIS board; Rx; Servos; CPU
and sensors
1. With a separate switching
uBEC - all ESC red wires
isolated - bridge closed - all
powered supplied by the
External uBEC
2. Without an external
uBEC - All our HobbyWing ESC linear BECs red
wires connected - bridge closed - all power supplied
by FlyFun ESC linear BECs - in parallel
3. With a separate switching uBEC - With power split - bridge
open - both the DC buses powered separately - CPU and
Sensors fed via the switching uBEC. ESC and Servos fed via
the ESC BECs - all ESC red wires connected - parallel
4. With a separate switching uBEC - With power split - bridge
open -both the DC buses powered separately - CPU and
Sensors fed via the switching uBEC. ESC & Servos fed via
the ESC BECs - ONLY one ESC red wire connected -
parallel
• We recommend option 2 (above) for most copters
if you are using our HobbyWing ESCs - not running high
curent gimbal servos. monitor the temp of the ESC in post
ight inspection.
• We recommend option 3 if running a bigger copter with a
gimbal. Do not connect +12v ever! only connect 5v to
the PARIS and set all uBECs to 5v (not 6v). Some switching
uBECs have been reported to be very noisy and conict with
PARIS 3v3 ic. If this happens revert to ESC linear BECs. option
2. above

Overview

1. Function Description
2. Important Technical Specifications
3. Usage Features
4. Maintenance Features

The device described in the manual is the MultiWiicopter.com PNP PARIS v4r6 Flight Control Board, a flight controller designed for various multi-rotor aircraft configurations, including Bi-copter, TriiKopta (or Avatar), Quad X, Quad +Plus, Y4, Y6 YSiix, HexiiKopta, and HexiiKopta X. It functions as the central processing unit and sensor hub for these unmanned aerial vehicles, managing flight stability, control inputs, and various auxiliary functions.

Function Description:

The PARIS v4r6 board operates by receiving control signals from a Radio Control (RC) receiver, processing sensor data (Gyro, Accelerometer, Magnetometer, Barometer), and sending commands to Electronic Speed Controllers (ESCs) to control motor speeds, thereby stabilizing and maneuvering the aircraft. It is designed to run the MultiWii software, specifically versions 2.2p, 2.2p Config, or 2.2p Application/program, which requires Java to run on a PC or Mac.

Key functions include:

• Calibration: The board requires initial calibration of the transmitter (Tx) sticks (Throttle, Pitch, Roll, Yaw, Aux1, Aux2) to ensure the correct uSEC readings (1095 for low, 1500 for mid, 1905 for high) are recognized. This is crucial for accurate flight control, arming, and disarming. ESC throttle learning is also a critical calibration step, performed one by one for each ESC.
• Power Management: The PARIS v4.0 boards feature a split DC bus to prevent noise from entering the CPU and sensor section. A noise bridge, supplied soldered closed, can be opened if using a separate switching UBEC for bigger copters. The manual outlines four power options:
  1. Separate switching UBEC: All ESC red wires isolated, bridge closed, external UBEC powers all.
  2. No external UBEC: HobbyWing ESC linear BECs red wires connected, bridge closed, power supplied by FlyFun ESC linear BECs in parallel. (Recommended for most copters with HobbyWing ESCs, not running high-current gimbal servos).
  3. Separate switching UBEC with power split: Bridge open, CPU/Sensors fed by switching UBEC, ESC/Servos fed by ESC BECs (all ESC red wires connected in parallel). (Recommended for bigger copters with a gimbal).
  4. Separate switching UBEC with power split: Bridge open, CPU/Sensors fed by switching UBEC, ESC/Servos fed by ESC BECs (ONLY one ESC red wire connected in parallel). The board operates on 5V DC; connecting 12V or exceeding 6V will damage it.
• Arming/Disarming: A specific stick combination (Throttle OFF, Yaw LEFT for 1 sec) is required to arm the motors, indicated by a solid green LED. Disarming uses the same stick combination, turning off the green LED. TriCopters have an alternate arming procedure (Throttle OFF, Cyclic-right for 1 sec).
• Flight Modes & Stabilization: The board supports ACRO mode for manual flight and AUTO LEVEL mode for self-leveling. Gyro calibration (placing the copter on a level surface, Throttle OFF, Yaw LEFT, Cyclic stick Back for 1 sec) calibrates for drift. Accelerometer (Acc) calibration (Disarmed, on a level surface, Full THRO/YAW LEFT, Cyclic stick Back for 1 sec) calibrates for LEVEL mode. Acc trimming (auto-LEVEL trimming) is performed after Gyro and Acc calibrations by flying in LEVEL mode, noting drift, landing, disarming, moving Throttle to 'Learn Position' (full up), and using stick-banging (moving cyclic stick up/left) to save corrections.
• Failsafe: The software has failsafe disabled, emphasizing the use of Tx failsafe. Users are instructed to bind their Tx failsafe condition with Throttle set to OFF (or 1/3 power for a controlled descent) to protect people and property in case of radio signal loss.
• LED Indicators: The board features a red LED (power to 328 CPU, always ON) and a green SMD LED (UltraBright White LED) that indicate various states:
  • Solid ON: Armed.
  • OFF: Disarmed.
  • Rapidly blinking 5 times: Cal.Sticks.Gyro.
  • Medium blinking: Cal.Sticks.Acc.
  • Slow blinking: Problem detected (start-up code error, calibration not done), after loading software, or if the board is tilted >20° (goes off when leveled).
  • Rapidly blinking for 30 secs: MAG calibration.
  • Once blinking: CPU computes a leveling correction.
  • Rapidly blinking 5 times for each stick-banging throw in ACC trimming "learning" mode.
• Connectivity: USB (via FTDI-USB) for configuration and power, RC receiver inputs (Throttle, Aileron, Elevator, Rudder, Aux1, Aux2), and various sensor connections. The board also supports Bluetooth mini USB, RS232 USB MINI, 3v3 GPS, LV GPS, or LCD.

Important Technical Specifications:

• Power Input: 5V DC (USB or UBEC/ESC BECs). Max 6V.
• Processor: 328CPU (likely an ATmega328, common in Arduino-based flight controllers).
• Sensors: Gyro, Accelerometer (Acc), Magnetometer (Mag), Barometer (Baro). The Acc is based on the Nunchuk®.
• Interface: Digital PWM uSEC numbers (1095/1500mid/1905) for Tx input.
• Software: MultiWii software (versions 2.2p, 2.2p Config, or 2.2p Application/program), requiring Java.
• Connectivity Ports: COM (serial) ports for GUI connection.
• DC Bus: Split DC bus with a noise bridge (can be opened or closed).

Usage Features:

• PNP (Plug-and-Play) Ready: The board comes pre-tested and calibrated from the factory, with code installed. Users are warned against loading default/new code, which can wipe existing configurations.
• GUI Configuration: The MultiWiiConf GUI (Java-based) provides a visual interface for monitoring sensor data, Tx inputs, and configuring various parameters (PIDs, flight modes, etc.).
• Tx Calibration: Detailed instructions for calibrating Tx stick travel (end points) and mid-points using the Tx's own menus (e.g., TRAV ADJ for JR, END POINTMENU for Futaba) are provided.
• Orientation: Light blue bars in the GUI must move in the same direction as the stick movement. If not, the Tx channel needs to be reversed.
• Propeller Configurations: The manual illustrates wiring diagrams for various multi-rotor types, showing motor numbers and their corresponding connections to the flight controller.
• PID Tuning: Users are advised not to alter PIDs like a "madman" if the copter isn't stable on default PIDs. Instead, focus on airframe rigidity, weight, balanced props, ESCs, motors, and smooth pilot inputs. Small changes (e.g., 0.1) can significantly affect flight characteristics.
• Saving Settings: WinGUI saves all settings. Users are recommended to save the Arduino Sketch in a new folder each time it's loaded and to screen capture the GUI settings as a backup.

Maintenance Features:

• Static Safety: Ground yourself/the board to the airframe to reduce static risk.
• Environmental Protection: Keep the PARIS board dry. The BARO sensor is sensitive to light and airflow, so it should be kept shaded, preferably with a dome cover (not foam).
• Propeller Balancing: Balance props on a magnetic balancer until silky smooth, then dynamically balance them on a hand-rig with a motor on a boom, using electrical tape.
• Pre/Post-Flight Inspections: Conduct full pre-flight and post-flight inspections, grounding the multicopter if any risk hazards (e.g., hot components) are noticed.
• Software Updates: Only use fully approved MultiWii software from the master coder AlexinParis. Using Dev or hacked software is explicitly forbidden and voids the warranty. Users assume full responsibility for any changes made in the Config section.
• Warranty: A 90-day repair/replacement warranty is provided, covering hardware defects. It excludes damage from fusion, reverse polarity, over-voltage, short-circuit, static charge, incorrect wiring, flood, crash, impact, incorrect tools, reflashing CPU comms/boot files, software hacks, moisture ingress, trauma, and misuse. Returns require an RMA number and detailed photo/video evidence of the fault. A 7-day refund is offered for DOA items due to shipping/manufacturing fault, provided the item is returned in original, un-used, un-modified condition.
