Combo deal - Gimbal + Alexmos
The Scarab Armoured-Gimbal Black for GoPro's, fully protected inside the GoPro protective case, allows the pilot to enjoy 180° of tilt freedom whilst flying filming & whilst being stabilised in 2 axis - PITCH and ROLL - So Scarab film makers can film forward ; down and most importantly upward - Fully stabilised. As the Scarab Multicopter itself can yaw 360° and fly in any other direction - it makes possible film-making not realised with other systems. Its our belief that high risk film making with a GoPro Action camera comes the need to ALWAYS - GET THE SHOT! - so its fundamental to our design that the GoPro fly fully protected and sealed up inside its protective action camera case. This created significant challenges to us from an engineering perspective and it would be easy to fly the GP3 naked and exposed like others have done - We just dont accept its OK to loose your film or your GoPro if you crash/splash or trip up at high speed whilst making ACTION movies - We also wanted to use our highly successful 8-Balls system for Gello Free video and mount the assembly on the front of existing or future Scarabs. This gimbal is 100% Metal/Carbon fibre with no plastic - and designed to be controlled by the PARIS Sirius™ Alexmos SBG controller board (sold separately - manufacturer by us at MultiWiiCopter.com).
Here is an example of a Erich's (see video below) gimal+Alexmos on a Scarab Vampire.
Below is another film made with a GP3 and a Vampire with this gimbal - its only a 2 axis gimbal but so stable it looks like 3 axis - thats how Vampire flies with the PARIS v5 autopilot - by Greggsy
Weight 192g (including 8-Balls VRS system;motors*2; all parts; 100% Full Carbon/Metal construction - 0% plastic (excludes GoPro ; excludes GoProCase)
Compatible with GoPro HERO HD 1, GP2 or GP3 Black, Silver or White - note : All GoPro must be enclosed in their GoPro Polycarbonate action case that came with your GoPro (GoPro camera and GoPro case not included in this price)
Designed for Scarab
180° tilt - live - prop-free filming whilst stabilised in 2 axis - film forward ; Down or straight up -> no props in view
(Notice how the sensor wires are fee to move unrestricted as the camera moves)
Excludes GoPro Camera GP1 or GP2 or GP3
Excludes GoPro action/waterproof/case which comes with your GoPro itself
Excludes final setup and balance of the gimbal with YOUR GOPRO fitted - GoPro must be in the full UW case - There are FOUR Balance adjustments
Firstly 1. Camera fore/Aft via GP mount Tilt and
2. camera vertical position via slider rails ; then Secondly
3. Gimbal Height via rotation of the cuff ; and
4. overall gimbal lateral balance via sliding the cuff in/out
Balancing a Gimbal in 3 dimensions - balanced means it will sit/stay in ANY position it is moved to, and will NOT attempt to move itself further or away from that position - this includes 45° positions - a gimbal which always rolls back to one position is NOT balanced. Ensure the gimbal has no drag or no tendency to sweep away from any positions. To alter any setting turn the holding screw anti-clockwise to loosen it. NOTE :screws are held by Loctite - this type of glue stops screws coming undone - Loctite glue is VERY hard at room temp or lower temps <35°c - to release any screw with loctite, simply heat it with your girl-friends hair dryer set to max heat (keep away from carbon)- heat the bolt so it is too hot to touch with your finger (85°C) - then the glue will become soft like butter and the M3 or M2 screw can be "released". For M2 screws use the 1/16th Pro-tool here
My gimbal shakes a lot >10° flick around randomly ?? - The Sirius™ contoller comes to you preset and pre-calibrated, so after installing the GoPro and Static balance process above - on power up- if you experience large >10° oscillations - POWER DOWN - simply reverse (turn-over) the gimbal motor black wires plug for that axis - ie - your motor is connected backwards - please do NOT try to alter/update firmware or setting or other radical assumptions - simply reverse the motor plug - it will immediately "lock-in"
Excludes Training - please be sure to understand PRIOR to purchase that balancing the gimbal using the 4 adjustment points shown in photos this page ; and routing wires (without drag/binding) is critical to satisfactory friction free operation. Please do not buy this product thinking its a consumer product - Quite the reverse is true as this gimbal requires expert puzzle solving abilities to balance it in 3 dimensions using the 4 adjustment points above.
Excludes assembly -(During the first release - free assembly is included - expires after 30 Sept 2013)
Excludes printed instruction - Buyers must use the resources-data-photos-video on this page.

----------------------------- FAQ Questions ------------------------
Question - is the Scarab Gimbal Black and Sirius controller waterproof for a float based multicopter?
Answer - no - the gimbal is designed to operate in AIR over water - not from, or on water - The idea of a quadcopter on floats was not considered during the design phase only flights over water from the shore was considered as it is something we do ourselves. A number of Scarab owners do fly from boats and simply catch/release their Scarab Quad by hand. Our Scarab Black gimbal is designed specifically to protect to the GoPro fully in the event of an accidental ditching whilst flying at the beach/coast in order to secure the footage shot - the copter, electronics and gimbal was a risk item in such an accident - Boaties You would have to embed the gimbal electronics in Sikaflex silicon and pack the bearings with grease for a float based copter - at your own risk. All sales are direct from AU to world. Products ship from AU to USA cities in 3-4 business days.
Question - Can i bolt this Gimbal to the bottom of my DIY Quad? All Scarab gimbals attach to a 12mm OD shaft at the front by design - Yes you could D.I.Y bolt a Scarab boom clamp set to any flat surface http://www.multiwiicopter.com/products/boom-clamp-delrin-set-of-4 - then insert a 12mm boom of any length from our store, then mount the Scarab Gimbal to that - It is NOT designed to sit under anything as a low/bottom position is inferior to the forward position by virtue of a) the props spinning over the gimbal prevent any possibility of filming forward/upward becuase Quads tilt down substantially when flying forward - in such a retro bottom mount, the shot will feature props spinning in the upper half of the shot - for this reason the Scarab gimbal was specifically designed to shoot from the front, exclude props, and surpasses retro bottom mounted gimbals. b) bottom mounted gimbals are always impacted in vertical crashes c) bottom mounted gimbals place the primary asset (camera/lens) in the dirt/ground/grass or your in case, the water
Question - I don't want to see any multicopter props in the FOV of my GoPro3 HERO BLACK using my Vampire Scarab. Do I have to extend the camera boom really far forward?
Answer by MultiWiicopter.com Pro-Pilot Quinton Marais No, it's much easier than that! - Keep the Gimbal assembly in close for weight offset and in any case 170° is seriously way too wide - As GP3 comes set at 170° too many pilots forget to use the more modest FOV when shooting <4K at higher frame rates like 60fps or 120fps on the "BLACK"- so the trick is to set your GP3 up correctly for FOV = Field of View. The GoPro3 Black records a full 4000x3000 pixels (4K) so its possible to get much nicer and sharper HD images (not accessing the edges of the lens) using the sensor cropped (but still not maginfied in any way) on other FOV rather than the "full frame" ultra wide - these are the 3 FOV's ; Narrow (90°), Medium (127°), and Ultra Wide (170°) - the 170° fish eye is great for underwater work to make the VIS look better than it really is - but 170° is not good for Aerials. Even the so called "narrow" is actually very wide at 90°
Question - I have assembled the Gimbal but my GoPro appears to be binding - stopping at one particular angle ? Answer = This is a set up issue - to help solve it post your DIY on the Forum HERE a) photos of your finished drone/gimbal ; b) a video of the problem c) your GUI & LPF settings (even if you believe they are default d) your voltage used
GoPro settings - MWC Favourites for 16:9 for the Scarab Brushless gimbal are
If your memory Card is small like 8Gb ( i recommend a 64Gb Class 10 card) then
For FPV flying we personally find that 120° is the best FOV to have enough peripheral vision and not too much fish-eye magnification error between near and far object/Altitude judgement - so that 120° for the FPV SD live-camera (We never use the GoPro to FLY - we always use a separate dedicated CarbonBird FPV-Cam) is very close to the GoPro3 Medium FOV anyway, at 127° - Also be sure to try 90° FOV for HD as well. You can read more about the various GoPro Hero Black setting available, HERE Dont forget GoPro Hero3 BLACK can also shoot simultaneous Video and Still images @1080/30 or 720/60 if ProTune is off - very handy thing to know :)
Marine or Salty Air environments - note we say AIR (Does NOT work in or underwater - i.e. in the sea)
If you need your GoPro fully protected and gimbaled 2 axis Tilt and Roll - in a marine air /boat mount / or a surf spray zone - then you must take additional steps to prevent corrosion

Everything is convenient except I wish it came with a boom at least 3 inches in length instead of two, in order to make it easier for custom diy mounting under traditional X shaped frames. (longer 12mm booms are sold separately on this site, remember to order an additional boom, if you need a longer mount)

Recently purchased this combo. I was looking to protect my GoPro Hero4 with the waterproof case somehow. Happy with the price and the incredibly fast shipping from Brisbane to New Mexico, USA. Seven days order to delivery using the DHL shipping.
I installed the gimbal on a DJI F550 frame, using a rail system and custom vertical plate to match up with the roll motor.
The assembly videos from the site are excellent but necessary since no paperwork of any kind comes with the gimbal.
Assembly is straightforward and pay attention to the roll arm module. There are "gotchas" there.
After assembly, one thing I noticed was that the motor wires are not marked in any way. I assume that it makes a difference which way the pins line up, but maybe not, since my 50/50 guess was the correct one. The motor connections on the controller are marked, "M1" and "M2". The video explains what motor cable goes where.
I am using 3S power to the gimbal, but it's recommended that you use 4S. The guidance I received was that the gains might need adjustment due to the lower voltage, but I started with the settings that were written in the controller as received and they worked fine.
Balance is something that needs close attention. Two points I'd like to make here are that using the GoPro mounting lugs is a plus and minus. The bolt needs to be very snug, otherwise the GoPro case can rotate fore and aft, destroying the pitch balance.
Second is the vibration killer balls above the camera vs. having the balls isolate the whole assembly. If the balls aren't compressed the same, side to side or front to back, the balance can be thrown off IF they loose compression unevenly. I did not use the bands that came with the gimbal, but used small wire ties on 4 of the balls. I measured the length of the wire tie tail to ensure they were the same length and compressing the balls uniformly. The balls need to be compressed because the top ball plate can touch the roll motor arm when it pitches upwards. It probably takes greater than 60 degrees up tilt to do that though.
I've configured the "real" Alexmos controller for both pitch and roll inputs, Beyond the normal tilting have allowed me to create mixes in my flight radio that mimic the "follow me"(follow the airframe) settings used if your flight controller doesn't have gimbal out control ports.
All in all, the fit and finish are quite good. I had questions before purchase and they were answered promptly.
I recommend this gimbal/and or the combo even if you don't fly Multiwiicopter airframes.
