8-Balls Gello killer - VRS system for GoPro & Sony Action Cam 12mm
The 8-Balls Gello Killer makes possible instant gello free video for Scarab or dji Phantom pilots who can never quite get the jello out ! - now its all done for you - is the V3 VRS - Vibration Reduction System for Aerial photography and video Ops. Designed for any GoPro - including GoPro3 or GoPro4 fully protected in the GoProCase/protective housing or Sony ActionCam in its housing. Fits all non-gimbal systems - Phantom, Scarab Armour 115mm ; Reconn 115mm ; Trikopta 75mm ; mini-triikopta 55mm. For gimbal systems ensure the gain is turned down for video (or upgrade to a better digital servo) - cut away the old GoPro holder with a dremel and install the 8-Balls Gello Killer VRS. Can be used with your balls in tension (hanging down) or in compression - see photos - the compression option gives the goPro a shorter drop for small airframes
Not sure what video-gello is? then this video below from USA pilot CrazyJ - shows the difference the 8-balls will make with one prop out of balance (tape missing). CrazyJ is a very experienced Scarab pilot and normally balances all his props perfectly - to be sure he was covered , he pulled a tape off - this is what he sent us below ..... skip to 1:05 for the 8-Balls version
Scarab 8-Balls Gello Killer ring system - level 3 VRS vibration reduction system
8 gel balls - the real deal

M3 Bolt and nyloc nut
M3 grub screw to lock to 12mm boom
12mm boom in your choice of 120mm boom/75mm boom or 55mm booms. Long boom cuts out props but must be balanced by LiPo moving back
Fits GoPro1, GoPro2 or GoPro3 ; also fits Sony Action Cam or any small camera with a bottom tripod mount - camera mounted inverted
BYO GoPro® - GoPro is a registered trademark of GoPro USA.
Note : If you have a gimbal be sure to set the software for low gain - MultiWii PARIS servo tilt =12
note 2 : VRS removes 100% of residual vibration gello and does NOT mean you dont have to balance motors and props - Balance all Props first - ALWAYS - otherwise you IMU will be vibrated !! bad bad idea
During assembly do not use sharp tools or excessive force which can rupture the gel balls
If you experience any camera wobble - use the compression band to increase the rigidity of the structure - can be tied one or twice around - see photos

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
