Trust data

For CarbonBird 2400kV motor on 4S :: these props ran 185g thrust@3.0amps@50% throttle ; 320g thrust @6.8amps 75% throttle and 385g thrust @11.6 amps at WOT which is 178w - so a match to this motor if WOT is limited to 3-5secs every 3 secs (so Efficiency of 3.8g/watt in a 740g Quad in the hover)

  • 2 props 5x4.5" as you see in Photo 1 at top right - BLACK - CW(R) and CCW

Excludes

We recommend to always check Balancing - These HQProps are near perfect as supplied (true centres) - they require almost no balancing, if any at all - However you must check each and every prop yourself - BEFORE FLYING - on a balancer - we found none in 4 set needed balance - but its up to the user to check and if necessary balance for HD Video
Limitations - Do not exceed the max RPM 19,500 - replace any prop if damaged or crashed - You must understand the risk of flying a Quad with a damaged prop can result in the Multicopter crashing/falling and hurting a 3rd party or yourself - YOU WILL BE RESPONSIBLE for this !  - props can cut - keep away from eyes!  wear safety glasses ALWAYS !
 
 
•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.  PROPS can CUT ! take precautions !  Never fly closer than 30m to/from any person or pet
 
 
Question - Can it use this prop on other motors - ?
Check the diameter of your motor shaft is 5mm and the depth between the spinner and the base <7mm or less - then you can pop them straight on.
