The wiki is de-centralised to make it easier to find product specific information - For wiki information for a MultiWiiCopter.com product or a sub-product - please go directly to THAT product's page on this website - or to the related page of a sub-product - ie if you are building a Scarab kit then information on prop balancing is contained on the Prop balancer page itself.  Information about ESC temps will be found on the ESC page (not the Scarab kit page) ; or information about care and setup of motors is found on the motor page ; information about a v4r6 PARIS on that product page etc..

Transmitter Calibration 


MultiWii software requires an accurately calibrated radio Tx - To do this it offers a USB interface called a GUI which shows you the output errors of your RC radio and allows you to correct/calibrate them to be accurate !  DO NOT SKIP THIS first STEP - see right - every transmitter is slightly different - Create a new model memory on the Tx and Call it PARIS.  Make sure your PC/Mac has JAVA loaded enabled - The GUI runs on JAVA - do a cold restart after installing Java - connect the Receiver (Rx) to the PARIS, connect the PARIS to your FTDI-USB - this supplies 5v power (after installing the FTDI drivers - HERE - cold restart) and turn on your Transmitter (Tx) and set ACRO(airplane) & PPM(not PCM).  If your not sure leave your Radio on factory settings.  99% of RC radios output PPM and work with PARIS out of the box.  Do NOT connect anything else yet (like ESC) to the PARIS ! -  then Launch the matching 2.2->2.2 Config or 2.2->2.2 Application/program on your PC or Mac or the latest code 2.2 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 actual critical uSEC readings - 1095/1500mid/1905 can be set. If you cannot get it exact then use 1090/1500/1910.   PARIS is a digital interface and the software running invisibly inside requires very specific digital PWM uSEC numbers to hover 100% auto-level, arm, 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 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 to 1500 on these blue bars.  Then move, one at a time,move each stick to the low position and set 1095; then move each stick/switch to the high position and set 1905.  Then go back and check all your midpoints are still 1500    Do this for all sticks and switches.  
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 Throttle bar should move up.  If you move your rudder right then the YAW bar should move right.
For Multwii code 2.2 or later (New Multiwii Code 2.2 use 1.0.5 Arduino HERE - make sure you use GUI 2.2 to match it -  clear the eeprom and make sure you recalibrate the ACC and MAG after any version changes - Calibrating a MAG means press the button and then rotating the Quad XYZ 360° in 30 secs)

Understanding RC Safety - MultiWiiCopters

for MultiWiiCopter PARIS customers; by AlouetteIII  © MultiWiicopter.com 2011
• Keep your PROPS OFF - not installed - until you are fully conversant/understand in full the functions of your Tx in full including TRAV (end Points), the arm and disarm procedures -  realise that for a noob skiping or out-of-order set-up steps or moving sticks, or even static -  PROPS may start at anytime without warning.  Never install props prior to calibration of the ESC and testing the gyro orientation, and arm/disarm testing of the board - YOU are responsible - make sure your actions and your Copter is safe.  Never ASSUME the props will not start - removing the props removes the risk.
Set Mode 2 (Throttle on left) Mode 2 mimics a real helicopter where the pilot operates
the 'Collective/Pwr' with his left hand - and the 'cyclic stick' with his right.
Set your Tx to ACRO (basic Airplane) mode - set PPM (not PCM), Activate Ch5 (Gear-Mode)
Read your Tx/Rx product manuals - You as the Pilot are responsible for safety.

Q. Whats Required to be a UAV Pilot in Australian Skies?

Answer = In order to operate an RPA on comm Ops (Remotely Piloted Aircraft – the new terminology used by CASA for an Unmanned Aerial Vehicle) for commercial gain (and this includes Uni's , Police Forces, Farmers or anybody who makes a buck directly or even indirectly from such activity - basically anybody except a hobby flyer) in Australia you require a Controller Certificate (CC) and the company that you will fly for (even if it is your own company) needs an Operator Certificate (UOC) In order to apply for a Controller Certificate 

For a CC you need to:

  1. Obtain an ARN (Aviation Reference Number) from CASA
  2. Contact CASA at uas@casa.gov.au for a letter of dispensation for the requirement to sit the BAK exam.
  3. Arrange with ASL or an approved flying school to sit the PPL exam.
  4. Complete your manufacturer’s assessment. Please contact RPAS Training and Solutions (RTS), a Sydney based company who can offer  manufacturer’s assessments for our Scarab/PARIS/DJI aircraft in AU.
  5. Obtain your Aircraft Radio Operator Certificate of Proficiency (AROCP)
  6. Log 5 flying hours on your RPA yourself and document all flights in a logbook
  7. Compete and submit your CC application form and supporting docs to CASA as a pdf. Currently the fee is AUD160

You can study for the PPL Theory exam at home or if you wish you can join a Full Time course. They have several courses available from 5 to 15 days or even weekend courses but I recommend you get away from your normal work and crack the 5-day Full Time PPL Theory Course at RPAS Training and Solutions. The course is AUD1,400 + GST and they even include an actual 1 hour flight at the end of the course to experience airspace use in-person. There is also an additional option to have an instructor come to your office - details on application.

The CASA PPL Exam is approx AUD150. RTS have an RPAS Training video explaining all the PPL requirements for the RPAS course as well as a Controller Certificate.  Once you have a CC in your hand you need to team up with a Certified Operator who has a Full OC - then work directly under his Company licence using his CASA approved Operations Manual and comply in full with his SMS and procedures, or you could apply for your own Operator Certificate. Hope this helps guys (& girls!) to become part of the drone world that's arrived and thriving.
