Product Description

These are the new HQ Prop 6x4.5" Bull Nose broad tip props (April 2015) 0645 bull nose (the name sux) -  1 *  sets of 1 x CW(R) and 1 x CCW(standard) medium pitched multicopter FPV props.  These are matched to 2212kv CarbonBird motors on 3S on Scarab 270 Air Knife mini Quad - 6x4.5 BN are best for bush-hacking extreme woodland flying FPV or racing. The tips are kept wide cord to allow them to hack thru leaves without breaking -  They require almost NO balancing - They are tough, due to the ruggedised "tip" design (but less efficient - shorter flights - than a normal 6*4.5 as the prop does not have the taper necessary to reduce tip vortex's).  Basically it's been designed to be tough - not to win an endurance comp - This colour version (GREEN this listing) hqprop-6x4.5bull-nose.jpg


  1. FPV Prop for bush wacking  - TOUGH 
  2. Strong ABS plastic
  3. Super light weight 6.3grams/ prop - perfect for rapid speed changes - required to stabilise multiwiicopters
  4. Suits 2212kv - 3S  - CarbonBird® motors or T-Motor navigator with 5mm hub  
  5. 5mm ID lip  - 3MM/4MM/5MM inserts included (you would have to drill out the lip with a reamer to use 6mm)
  6. Requires 9.1mm shaft height ; 5mm diameter shaft to mount it.
  7. These are high quality props for a great low price - made by HQ Prop - have passed all our MultiWiicopter tests - but you must adhere to safety warnings about props below - always.
  8. require almost NO balancing (always check every prop and use 800 grit wet-n-dry to remove any sharp edges at the leading edge of the blades)

Things we don't like so much

  1. Efficiency is lost by making the tip strong and blunt (Bull Nose) - the tip is effectively producing bigger vortex's - leading to reduced flight times compared to the normal 6*4.5 (see chart below)


  • 2 props 6x4.5" as you see in Photo 1 at right - GREEN1* CW(R) and 1* CCW
  • 3 insert sets *2     3/4/5mm (5mm normally used)


less 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.
