Our MultiWiiCopter Control boards PARIS Sirius allow you to build a multicopter which can produce excellent video and still images.  SCARAB MultiWiiCopters are much are VERY stable, Rigid and strong - engineered to be minimalist (low drag booms)  Scarabs offer longer flight times for LOS and FPV.  Quad SCARAB Kits require assembly which takes 5-9hrs depending on the experience level/ability with tools, soldering wires and balancing props.  Flying is fun but rest assured that EVERY expert flier is ALSO an EXPERT builder - it goes with the territory.  We encourage you to build and learn.

 


(ABOVE) The extreme light weight Dupont Delrin and Full 3Kweave 2mm Carbon in this SCARAB - make possible handling that allows a Scarab Stealth Armour Trainer
to be flown on a PARIS in ACRO mode with fast yet stable results - CrazyJ in USA shows us how it handles.

Noobs - Building can be very satisfying and educational.  Below are series of build-videos from one of our customers at Expert Level "Deet" - its worth absorbing all Deet's building recommendations and combining that with the photos and instructions on the product pages themselves and downloadable instructions.  Thanks to "deet" for his build videos.  Please note that Deet methods are his own, and the aircraft/versions he owns may be different from the newer versions you purchase.  Its a great way to spend some time seeing an expose of an expert builder and how he does things "his way". 

 
 
 

The success and the stability of your multicopter SCARAB Kit controller by your PARIS Sirius will depend upon pilot skill , correct use of modes, your disc loading and how well you balance your props.  If you build lite and keep the aircraft lite it will fly like a dream.  Usal payload is a GoPro HeroHD2 or HD3 , a Panasonic GH2/GH3 or Nex5/Nex7 or a NikonV1/J1 camera.  SLR cameras can be flown but their large heavy mirror designs are irrelavant in the air when the pilot is actually on the ground not using the mirror box.  The new generation of mirrorless cameras such as the GH2/GH3 and Nex5/Nex7 which produce Pro quality video as minimal risk - a 1-3kg multicopter has far less energy, less noise and risk to person and property on the ground, compared to a 6-9kg copter carrying a DSLR.  In making your Airframe we recommend a Quad as a trainer aircraft - followed by a 2nd aircraft later - a six engine Multicopter like Vampire or YSiix to conduct professional photography as this offers single engine redundancy - should an engine fail then a six engine multicopter can fly on the remain 5 engines.  A light fpv quad is 650g and a larger Scarab Quad is 1350g with LiPo and mirrorless camera onboard.  Above this weight we recommend Vampire and YSiixKopota for better payload.  If you are a beginner you CANNOT jump past the training phase - you must start with a SMALL QUAD TRAINER

The MultiWiicopter commandments  - We wrote this list in blood and sweat - this is not some cheap cut-n-paste - read and learn - 

  1. Balance all Motors - dynamic
  2. Balance all Props - static and dynamic
  3. Check all Prop adapter collets and shafts are true - not bent - secured with identical torque
  4. Mount all sensors on gel or gel foam tape - always (never use closed cell tape like 3M for hme use - it has not gel properties)
  5. Mount all GPS/MAG pods well away from all RMI ESC and the main LiPo
  6. Solder all wires with solder flux paste like Amtech 223 - don't use cored solder or weak soldering irons
  7. Set all failsafe channels and test them LIVE on your PC/Mac to check the stability of the RC signal
  8. Do a proper RC range check of the RC radio with all FPV gear powered on
  9. Test all FPV gear at 200m on the ground - dont setup FPV 2m apart then fly ...  you might be on an adjacent Ch - so do it right - check all channels at long range on the ground first
  10. Check all push connectors are firm, even - Spray INOX lanolin to ALL connectors !  - loose or soft connection cause engine/esc failure
  11. Check all data line are 100% secure - tied but not pulling
  12. Check all props for fatigue cracks or stress fractures
  13. Do a pull test on all Props before every flight to check security
  14. Do post flight temp checks on all ESC and all motors - 50°c max motors and 60°C for ESC
  15. Telemetry Monitor every cell of the LiPo in flight - do not rely on total voltage alone
  16. Route all data lines well away from ESCs
  17. Operate the CPU/IMU on a dedicated 3S DC bus for large multicopters - a separate 2S or 3S Lipo with uBEC
  18. Check all wires for airframe abrasion or shorting - use a diamonf file to dull sharp edges
  19. Check the airframe is grounded to prevent static entering data lines - props create static - it has go somewhere
  20. Separate all RC receiver antenna wires by 90° and keep away from carbon structures
  21. For all push connectors - ie s800 booms or RC plugs - use Inox or Corrosion-X or similar sprays - less is more - blow away excess with an air gun
  22. Ground your aircraft at the slightest hint/sign of abnormal ops of any component
  23. Remove all risk - if you fly over a crowd of people the risk is falling - so don't fly over crowds
  24. Program and test GPS return to home - be 100% familiar with GPS over ride procedures and fly on MANUAL if req'd
  25. Never assume - problems come in groups - its never just one thing, if you find a problem - look again
  26. Use loctite - Make sure the entire airframe is 100% rigid and secure - vibration can loosen flight critical parts
  27. Use a checklist and stick to it 
  28. Wear safety glasses - props can cut
  29. Calibrate all sensors - check on your PC/Mac.  Always connect main Lipo with aircraft level and DONT move the copter in the first 10 secs after connecting LiPo!
  30. As the pilot in command EVERYTHING is your fault - if anything goes wrong - YOU as the Captain are responsible

The recommended weight is directly linked to performance and stability - Low weight Carbon fibre is best - do not over-build for un-necessary strength; do not make it heavy.   If you cannot afford carbon then use our lightweight 12mm booms made from very thin aluminium.The small round (circular) cross section arms; Low pitch propellers (8x4.5, 9x5triples, 10x4.5, 12x4.5); light weight outrunner brushless engines with a low kva (kva varies with size of props ie  on 3S 12v LiPo a 1220kva motor the 0845 is good and 775kva the 9050 triplesfor 4S) and a high "C" rating LiPo of a modest size (heavy LiPo cell do NOT give a longer flight time); You want a large amount of slow moving downwash and NOT a small amount of high speed downwash for STABILITY.  Do not make the arms too long(flex) or too short unless very light weight (stability).

If you prefer to Goo-search the internet (goo-search is our word for so-called internet research) and see what others are doing there is a lot of recommended reading and examples below: -  Please remember on Google you will find many examples that are badly designed and a small number which are well designed - a well designed SCARAB multicopter can fly for 12-15mins.  A video showing a 4-6 min flight; or less;  means it's a VERY inefficient/design multicopter.

A note for multicopter beginners

The rapid development of Multicopter has come from community open sorce collaboration.  You stronly recommend you read and contribute posts on the MultiWiiCopter RCGroups Forum thread for PARIS and SCARAB -  It is possible to get involved in multiWiicopter construction without a background in RC, aviation or electronics, however you'll find a reasonably steep learning curve. You will need to develop an understanding (but not necessarily mastery) of subjects including temperature controlled soldering, speed controllers ESC's, lithium batteries LiPo  (i.e. safely charging), radio control, low-voltage DC electrics, propeller balancing and more. Communities such as the RC Groups forums will help beginners find their feet, but please read the various getting started guides, threads and FAQs before you post a question that has been asked and carefully answered before.
