Includes

  • Roll gimbal assembly and hardware
  • CNC 2mm metal tray with 33 1/4" holes for tripod bolt alignment to any APS-C camera
  • Metal Gear servo HiSpeed - Coreless
  • M3 bolts to mount the servo x 4
  • Ball-link roll change rod/2 rod ends/2 ball ends
  • Instructions to assemble - comes as lots of small parts
  • Carbon fibre 26mm servo tray - holder
  • Stainless Steel M5 bolt & Nylon M% bolt (lighter)
  • Servo extension lead
  • Total weight with servo 109grams - solid - forms a structral component of the MainFrame of your SCARAB
  • MAXIMUM camera weight is 400grams
  • Down-loadable Gimbal assembly manual - HERE 
 
 
Fits with -  Fits directly to
  • SCARAB TriiKopta
  • SCARAB QuadOcta
  • SCARAB YSiix
  • SCARAB Stealth Recon 
  • SCARAB Vampire

In MultiWii 2.3 or later, the gimbal TILT angle , TILT_PROP and ROLL-PROP the rate to match the tilt of the copter to the servo tray tilt is now in the GUI, not in the code like 2.2

  1.  in the GUI 1st tab ; activate the CAMSTAB boxes (choose alway on (3 white as shown)  or by switch set only one box to white)  - press WRITE
  2. multiwii-camstab-settings.jpg
  3. a new tab called SERVO will appear next to that called SERVO - in that tab press GIMBAL and then READ 
  4. Now set the value you require to toget the correct ROLL and centre point - then SAVE

Requires/Excludes

  • Excludes PARIS Sirius autopilot - this sends the commands to remain level a PARIS Sirius AIR or PARIS Sirius™ v5r3
  • You will need a 1/16th Scarab frame tool Hex ; 1.5 mm hex tool ; 2mm hex tool ; file or diamond file ; Blue Loctite® ; sidecutters ; Servo centering device
  • Requires thin cyno
  • You will need to supply your own APS-C sized video camera - with its original housing - requires some deburring and 1 drop of oil
  • You will need modelling/engineering skills to assemble it - NOT a toy - requires 1hr to assemble in a workshop
Software for EE's and coders
For MuliWii PARIS driven code - smooth options to remove jitter 
 
What it does:
  • Tries to smooth out fluctuations (jitter) without the usual negatives of slow response to large changes.
  • When the gimbal is approximately in position, it makes only small changes. Smoothing out spikes and jitter.
  • If there are big changes, it stops the smoothing and uses the real value and restarts smoothing around that if its still stable.
  • It also introduces a deadband to ignore the bulk of jitter
  • It uses an algorithm that is very light on memory. 20% of the current default gimbal smoothing. 10% of the value I typically need to use.
The negatives are:
  • Increasing smoothing values starts to increase stepped changes when the copter is changing angles
  • Full smoothing (value=250) and it creates a slow response (1 second full transition at max smoothing)
 
Its a balance compromise as always to keep simplicity and fast code
 
    /* Gimbal smoothing : anti-jitter gimbal smoothing for AP  */
    #define GIMBAL_SMOOTHING          //Uncomment to enable gimbal smoothing 
    #define GS_DEADBAND       5       //PWM Deadband. Within this variation servo output is locked
    #define GS_LIMIT          35      //PWM limit. Above this fluctuation, smoothing is disabled. Higher = more smoothing / but starts to introduce more stepped changes
