Product Description

These are the HQProp 12 x 4.5 high RPM  multicopter props (8 July 2015) -  sold as a matching sets = 1 x CW(R) and 1 x CCW(standard) low pitched multicopter props.  These are matched to the 888kv CarbonBirds on 4S. Its incredible how they are NOT Graupner e-Prop clones, but are amazingly similar - only better balanced ; 33% lighter and similar strength - wow !   Running a larger prop turning more slowly increases flight time - as efficiency is higher with a slower rpm ratio - however you still need to make sure you are not over-propped and that the motor temp is cool/warm only

Features

  • 12x4.5" CCW /CW
  • Nylon for high RPM = 9,000 rpm - realistic multicopter Ops 7-9,000rpm
  • Scarabs -> We tested these on a 888kv Carbonbird at 100% throttle = 8105RPM ; 255 Watts ; 16.4Amps ; 15.1 Volts produced 1321g thrust  at wot ! - hover 50% throttle = 4.3amps 590g thrust - suits a 1.5->2kg Scarab Quad such as QuadOcta HERE
  • Low inertia mass 16.6g (much lighter than Graupners - a good thing for fast RPM changes)
  • 6mm ID  - 6MM/8MM/9.5MM staggered inside tapers - (requires a prop REAMER - NOT included) - comes with 3MM,4MM,5MM,6MM adapter rings which go into the lower side.
  • Requires 8.5mm shaft height ; 6mm diameter Ø shaft to mount it.

 

Includes 

  • 1 x 12x4.5 CW
  • 1 x 12x4.5 CCW    (total 2 props) 

 

•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 !  Wear Eye protection ! take precautions !  Never fly closer than 30m to/from any person or pet
