Product Description

These are our budget OEM CarbonBird® 4 petal Collet shafts for crash replacement if bent - With Multicopters it's critical to have a 100% perfect straight/true collet shaft to ensure the prop is rotating dead-centre.  In the event of impact the CarbonBird motor shaft will usually fail at the machined failpoint (small groove machined into the shaft) but if the shaft is reversed then these force can be absorbed by the Collet (this item) and it may be off centre - and is best replaced.  


Dimension & Data

  • Weight 1.2grams
  • OEM Carbonbird collet 
  • ID 3.17mm
  • OD 4.96mm
  • OD M5 threaded shaft 27mm L ; threaded section 15mm

Note : a Collet must be attached to a motor shaft with loctite™ ; to Remove a collet , remove the spinner, remove the prop and lower red collar, then first heat the inner collet to 145°C with a heat gun (avoid heating magnets) then the loctite will be very soft and the collet will release from the shaft - To remove dried loctite, use the solvent Acetone - normally just place the removed collet in acetone for 20 mins and it will be very soft and wash away easily.



One Shaft ONLY - 4 petals (only fits silver collar - does NOT fit red collars)



other parts of the collet ; M5 nut ; Tapered lock ; Spinner - re-use these other parts from original supplied with your motor


*NOTE : Its possible to bend an aluminium collet straight by first spinning it - marking the side which is running wide with a permanent ink marker - then bending it away from the mark by the same amount - be aware that metal fatigues oif bent back too many times and may fail.

  • Information on assembling a kit can be gained by looking at the photos on the product page itself. If you stuck on an advanced kit then first read the Quad Noobs guide
  • MultiCopters should hover at 50% throttle and fly for 10-15 mins.
  • Balance all props - vibration causes junk sensors data and gello in video - remove the SOURCE of the vibration by balancing
  • Use a quality prop balancer(Du-Bro 499 Tru-Spin Prop Balancer) statically; then run them individually to check they are centred true and the tipshave the same path; any vibration will reduce the effectiveness of the Wii gyro or anyother gyro.
  • Attach any IMU or sensors such as Sirius™, NAZA or WookM with vibration isolation gel - Board with sensors solder to directly are just cheapo clones - commercial quality IMU use isolation vibration materials
  • 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 - remove the prop -remove the risk.
  • Always maiden on default PIDs' - If the copter is not almost perfect on default PID's then DO NOT go straight to altering the PID's! Most of the problems you will face as a noob will be caused by making wild assumptions or following myths from forums - fly on default PIDs first - balance your props - make sure your ESC are calibrated and synchronized.
  • Dont be fooled by forum claims of kirby flashed ESCs - this software will melt your ESCs and give short flights - there is a lot of bad info on forums

Safety in Australian Skies

  • Keep more than 30m from persons,choose an empty sports field for your first flights
  • Do not fly near pets, houses or cars
  • Never fly within 3nm of an airfield or above 400ft
  • Never install your props until after the Multicopter is fully tested and 100% correct without props. Engines can start suddenly and without warning IF YOU FAIL to understand how they work or skip any steps.
  • Set your Tx/Rx binding to low throttle 1/4 position so that if the link is lost the copter will descend slowly.
  • Always keep your Copter in line of sight for one pilot ops - FPV is only legal in AU with a buddy on a buddybox - 2 person FPV is 100% legal using the buddybox system below 400'.  See CASA Part 101 Regs
  • RC Flying is a privilege - please enjoy it.  Don't show off and don't get over confident
  • Home movies are fine, but in Australia professional paid photography or videos from an RC aircraft requires CASA Part 101 compliance, including exams and approved ops manuals and pilot competency tests by CASA official which will cost several thousand up front.

Safety in USA Skies

USA multicopter Flyers be aware - FAA D.O.T USA published an AC 91-57 (Advisory Circular) on June 9 1981 to keep flyers of models away from populated areas (people) and minimise hazard to persons and property on the ground - the intention is conveyed by this AC - It is titled Model aircraft operating Standards - Para 3. a) to e).

Clearly stated are the 400ft height limit and not closer than 3nm from an airport and the avoidance of populated areas and parks.

Once used commercially a model in the USA becomes a U.A.S and pilots should read this document regarding the use of multicopters for Comm Ops
