The is the legendary Full-metal-jacket Alexmos - the PARIS Sirius™ Alexmos Black controller - a fully licenced hardware/software product to control ANY high quality brushless gimbal - the electronic hardware you see here is 100% developed by the MultiWiiCopter team and is unique - It is minuturised and hardened 2 axis SBG Gimbal Controller with a full metal jacket to keep the motor driver circuits fully cooled and impact protected via the case itself - yes full aluminium cases - both for the main board and also a miniature metal case for the on-camera Sensors as well. To take the product further we designed it around a small 4 layer PCB (making it the smallest SBG on the market) and orientated all the control wires to the front and the input wires to the rear such as camera live-tilt via RC Ch7. We also included fast USB ; a multifunction program switch ; a molex connector with 8 outputs. NO Soldering - No programming - Ready to Use*(with Scarab Gimbal - requires minor re-programming/Tuning of PIDS for other larger gimbals IF the sensor is moved)

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"
How to use the PARIS Sirius™ SBGC Black
- Fly your Scarab multicopter first with no gimbal (use a similar weighted object (of the combined camera/gimbal) in its place to ensure the aircraft PIDS are accurate for the total weight!) and make sure a) that you can actually fly it well and b) that you have removed all vibrations and c) set your aircaft gains (PIDS ) correctly with no over gaining - choose your props wisely - very stiff carbon props are NOT ideal for all ops - such as fast flight. Get your flying skills to the point where you no longer crash the aircaft and are not "afraid" of it regarless of which mode it flies in. If you are terrified of manual flying (Called Acro mode) then you are not ready for a gimbal yet - practice your flying and get lots of air time. Once the aircraft and you are both flying regularly with no problems at all ;
- then - PROPS OFF
- Balance your Gimbal in 3 dimensions - balanced means it will sit/stay in the position it is moved to, and will NOT attempt to move itself further - this includes 45° positions - a gimbal which always rolls back to one position is NOT balanced. Ensure the gimbal has not drag or no tendency to sweep away from any positions.
- At this point you need to make a risk based decision - should you a) do an advanced calibration? or b) proceed without doing one? We recommend NOT to do it now if your a noob or even if your an expert and rushing. The advanced calibration makes the gimbal more acccurate if the craft is yawed a lot/fast yaw (generally a really bad techique of a pilot as fast yaw=horrible aerial video) But if you wish, at your own risk - then do step 9. below, now - before attaching the Sirius™ SBGC to the copter or the gimbal. Be advised advanced calibration is for experts - and noobs can render the device un-usable if they don't understand this process fully. In most instances you will get VERY good results without doing advanced ACC calibration. Please note that temperature variations effect Gyros/Acc a lot - so dont do all your calibrations at 30°C then carry your aircraft out into -2°C - because you will get tilt errors from temp variations like this.
- Connect the roll motor to M1 ; connect the pitch motor to M2 - be sure the wires do not bind pull or tug
- If you wish to have Live-pitch camera control connect the 8Pin Molex wire - use two wires only - (we recommend to remove entire from the molex all other wires or to place them in a position away from electronic feedback from ESc or other devices on the multicopter) - The 8 pin molex attaches to the rear of the Sirius™ SBGC GND & RX-P to the RC Receiver channel 7 - Red goes to the "~" pin of your Futaba/Spektrum Rx and the black GND wire goes to the "-" negative GND pin of the Rx - Check your RC Radio "SERVO" window to ensure you know which switch - or knob - controls Ch7 and that it is active.
- Mount the Sensor (small metal case) at the back of the camera as close as possible to the centre of rotation - be very carefully to do this accurately - the arrow must face up to be used as pre-programmed by us - use the supplied VHB tape. Route the wires in such a way as they are NOT trapped and free to move - the wires should essentially follow the path to the centre of each axis so the camera is free to move up or down or rol left or right - WITHOUT the wires pulling on the motors
- Turn the GoPro (Camera) on NOW - check all your GP3 settings - after this you will not physically touch the camera again. If you have aGP3 black activate the remote (internal blue LED in GP3 will flash)
- Hold the Aircraft still not moving - ideally on its landing gear - still - then. Carefully check polarity (red to red - black to black) and Connect power to the JST pigtail - 4S 16.8 main aircraft power is recommended
- Wait for 10 secs - you will observe the camera resolve its position and rotate tilt to face forward. if the camera moves the wrong way then the motor connectors can be reversed (remove all power) rotate the 3 way motor wire plugs 180° and then reconnect power ( if the camera moves/wobbles or struggles - its a gimbal issue - DO NOT ASSUME its a controller issue because 95% of problems are gimbal drag, gimbal imbalance or user setup balance or incorrect wire attachment errors)
- If your gimbal continues to shake or tremble - then immediately power-off the gimbal - If the motors over heat its your risk and your FAULT - the user must monitor temperatures of his gimbal motors - high temps will damage your magnets - the preset voltages in the Sirius™ SBGC are set for a Scarab gimbal and not other cheapo cloner gimbals.
- The Sirius™ SBGC calibrates its gyros at startup (temperature sensitive - The acc is already calibrated at our factory for the arrow on our sensor case to face vertically, attached on the rear of the camera. Its possible to do an advanced ACC calibration - However - a badly managed re-calibration will worsen your result - At your own risk - Advanced calibration requires moving the Sirius™ SBGC sensors to the six postions (so each of the sides of the metal sensor case face upward in turn - motionless) - then pressing CALIB.ACC
- If the gimbal is operating smoothly - your as clever as you think you are - otherwise probably not.
- Move the aircraft around the roll axis slowly and around the pitch axis slowly - you should NOT hear or see any movement or play - dont be tempted to make wild movements to impress your inner chimpanzee - listen for humming or resonance - this indicates that there is play in the gimbal (play is the No1 enemy of all gimbals) - Play is causing the sensor to oscillate one of the motors. DO NOT rotate the aircraft 360° as the gimbal motors may react suddenly and damage your motor wires.
- Monitor motor tempsMotor Power settings in small increments. Thermal runaway is not linear - its a very specific setting - so for example the motor may run cool all day on 150 power setting - but will go thermal and melt down at 152 power setting. Never walk away and leave your gimbal running.
- Test the RC Tilt control - we recommend it be attached to a 3 way RC switch - take off and fly with the switch in the middel position - to film down flick your switch forward - to film up vertical (only possible with Scarab gimbals) flick your switch back - the software on the Sirius™ SBGC will handle the speed of the transition.
- Fly the camera and test hovering - slow yaw - fast forward and banked turns - then tilt the camera up or down if you have pitch live-RC control - land
- Power down the gimbal first - then power down the GoPro/Camera
Keep Dry - Do not expose to moisture/rain - place the Sirius™ SBGC under the clear dome to keep it away from getting wet.
Power down before making any connections ! Be sure to only connect INPUT power to the pig-tail JST lead - do NOT connect power to the motor outputs
Keep away from salt - salt air - or worse salt water - will void your warranty instantly
DO NOT attempt to pull the I2C wires out of the sensor ! Force will damage or break the wires. If required for routing of wires -> remove the wire/connector on the CPU side. In order to remove the plug from the camera /sensor side you need to unscrew the 4 small screws first!
Warning - DO NOT PLACE DIRECTLY onto to LIVE Andromeda board pins - you must use VELCRO to ensure the metal case does NOT short the Andromeda pins - if mounted as per our photos - be aware we have used male-female velcro underneath in this example.

Question - My PARIS Sirius gimbal is not level - it is tilted to the side/down a bit? How do i get it perfectly level?
Answer = Balance it and redo your gimbal ACC Calibration (basic Cal)
- firstly the gimbal and camera MUST be balanced in XYZ axis - see above balancing
- Disconnect the 2 motors 3-pin plugs from the contoller - the gimbal will be limp , but balanced (with camera fitted)
- Use a clamp or a piece of foam to hold the camera pefectly level (see the bubble in the bubble level is in the middle)
- Make sure the Camera IMU on the back of the GoPro case is perfectly set at 90° true, firm
- Connect the Gimbal controller Black to a PC or Mac by USB and run the GUI - make sure you dont move the gimbal during power up as the Gyro.cal occurs in the first few secs after power is applied to the gimbal (USB 5v is enough to to complete the calibration - but if you like you can also use the main LiPo - we dont use it for Acc.Cal
- The GUI should look almost exactly like this
- With the gimbal bubble level showing the bubble in the middle = "LEVEL" - then - press CALIB.ACC
- wait 10 secs for the calibration to complete
- remove the clamps/blockers holding the gimbal - connect the 2 motors again - power up on 4s - the camera should be perfectly upright once it stabises - if NOT make sure the sensor axis is -Y and -X - see above image. Also make sure your not Commanding it to roll or tilt via the rear inputs and your RC Tx pots?
Question - How to add a 5v Rx - Is there a 5v outlet inside the PARIS Sirius Alexmos?
Yes - for expert EE you can find 5v for a receiver here - modifcations will void your warranty - but one person already reported it works well
