High RPM Prop set of 4 - 9x5 L-R Graupner eProp E-Prop 1326.9L-R Multicopters CW CCW

Product Description

High RPM Super-Nylon Prop suited to Scarab Multicopters running very High RPMs such as Scarab TriiKopta and Scarab YSiix - Max rpm = 14,940. Made in Germany by Graupner these props by design have very steep inboard section and rapid taper chord-wise - provides slightly less thrust overall compared to a similar 9 x 5 slow flyer prop (spoon) but provides superior stability of flight in multicopters due to the high inside radius airflows and low tip loading. Very Rigid making them less suitable than 9050 triple for fast forward filming work. Suits experienced prop balancing FilmMaker - not for Noobs doing film Ops.

Excludes training on how to balance props for video Ops

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. When operating props remain clear of the spinning arc plane - at all times wear eye protection.

Tips

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.
