Blackbird closer to your body without bumping into it But you can also position it front to back parallel to the camera B Mounting the Camera Remove the camera mounting plate from the stage by loosening the clamping screw on the stage Attach the mounting plate to your camera with the 4 20 screw Drop the camera and mounting plate into the top of the Blackbird stage and tighten the clamping screw By loosening the mounting plate camera screw the camera can be moved front to back The safety pin on the top of the Blackbird stage prevents the mounting plate from sliding off the stage even when the clamping screw 1s a little loose Always check that the clamping screw is tight and camera is securely clamped before using the Blackbird Which Mounting Hole to Use Locating Ri d 1 Y 20 camera scre 4 3 s 3 S Blackbird User Manual Page 8 Place the 44 20 camera screw in the hole that you think will locate the center of gravity of the camera directly over the gimbal Or just start with the 2 hole in the middle of the camera mounting plate and check balance The locating pin screws into the appropriate hole If during balancing you cannot get the camera level by adjusting the front to back and side to side knobs then move the mounting screw appropriately For example if camera leans to your left then move the screw to one of the holes on the right 3 or 6 Note DSLR cameras do not have a hole for the locating2. first remove the gimbal and handle by loosening the locking nut and then unscrewing it counter clockwise completely out Then insert the gimbal extender and lock it into position with its own locking nut Finally re insert the gimbal and handle into the bottom of the gimbal extender and tighten its locking nut Just like the gimbal the extender has a thread cutout to indicate when you shouldn t have it out any further The maximum extension for the gimbal extender is shown at left When you just begin to see the shiny thread cutout it means DON T GO ANY LOWER Page 11 Blackbird User Manual G SmoothTouch friction adjuster The roll and tilt axes friction adjuster is located below the gimbal center block When turned clockwise it increases friction in the tilt and roll directions Turn it counterclockwise to reduce friction note 1f the knob turned counter clockwise too far out it will touch the gimbal lower yoke and the gimbal will not rotate freely Observe the freely swinging handle to see the amount of friction being added To do this support the Blackbird with one hand under the camera stage and lift the gimbal to about a 45 degree angle and release it With no friction it should pendulum about 4 to 6 times before coming to rest As you adjust more friction and drop the handle you will see it come to rest after fewer and fewer pendulum swings With a very high friction adjustment the handle will just overshoot vertical an

8. e amount of bottom heaviness is described by measuring the drop time of the rig as shown on the next page Adding some gimbal friction with the Smoothtouch control will also help reduce undesirable pendulum motion Blackbird User Manual Page 16 When you hold the stabilizer in the horizontal position think of it as a simple mechanical balance where the gimbal is the fulcrum or pivot point of the balance like a see saw If the rig is bottom heavy then when you release the T bar the counterweights will drop down Count the seconds from release until it just swings through vertical and that is the drop time Drop time a is recommended to be about 1 5 to 2 5 seconds Note that to get a good drop test the stabilizer should be at least roughly in balance one side instead of dropping all the way down below before checking drop time horizontally If the Blackbird wants to rotate on its pan axis when you release it or if it leans to this is a sign of horizontal balance being off So with the rig in any bottom heavy condition first do a horizontal balance see horizontal balance Vertical balancing to get the right drop time can be accomplished by a combination of three adjustments which are e Using different amounts of counterweights on the horizontal bar e Adjusting the position of the T bar up and down e Adjusting the position of the gimbal up and down Page 17 Blackbird User Manual Procedure to get rough v
9. ertical balance 1 Set the T bar position to about 8 on the scale just a starting point with room for adjustment 2 Refer to Table 1 below and put the suggested counterweight combination for your camera weight on each side of the horizontal bar 3 Hold the Blackbird in the horizontal position and note whether the counterweights tend to drop or go up 4 Ifthe counterweights don t drop then you must add more counterweights until they do to get the bottom heavy condition 5 Release the counterweight bar from the horizontal position and count the time it takes for the counterweights to fall from the horizontal position 9 o clock to the bottom position 6 o clock This time is called the DROP TIME 6 If the drop time is less than second very bottom heavy then you should remove some counterweights Once you get a drop time between about and 3 seconds you must make a horizontal balance before making the final drop time adjustment Table 1 Suggested Counterweight combinations Camera Weight lbs Gimbal extender Weights each side Yes Yes B Horizontal Plane Balancing Horizontal plane balancing means adjusting the Blackbird so that the camera is level in the tilt and roll directions in other words it sets the framing of your shots when you just let the stabilizer float Fortunately horizontal plane balancing is easy and it is an adjustment that you may do frequently when shooting And most often when shooting you

17. ure that allows you to add friction to the tilt and roll gimbal axes can help you get noticeably better shots It accomplishes this by damping gimbal motion while still maintaining reasonable gimbal isolation of hand movements You will find that adding even a large amount of gimbal friction has a small effect on the drop time with the normal 90 degree drop But it can make adjusting horizontal balance much less sensitive In other words for small angles off vertical in either the tilt or roll axes say a few degrees up to 10 degrees there can be significant damping So with high gimbal friction you may want to shake the handle gently while setting the horizontal balance E General guidelines and strategies for vertical balancing and setting up the Blackbird 1 For best performance try to balance the rig so that the T bar is nearly fully extended Itis a mistake to think that if you add some counterweights and move the T bar up to maintain vertical balance that you will have a more stable rig If you do that you will have a heavier rig that has LESS moment of inertia in the tilt and roll axes only the pan axis will benefit from the added weights 2 If you want to take low shots and want to get the camera as close to the ground as possible or you want to minimize the chance of bumping into the weight bar then you should balance the rig with the T bar raised up appropriately 3 If you want the lightest weight rig then adjust the gimbal high c

19. y would you want to adjust the gimbal postion Answer Adjusting the gimbal position gives you an additional adjustment for vertical balance in addition to adding or removing counterweights or changing the height of the T bar See part III A Vertical Balancing The gimbal stem screws into the bottom of the camera stage and is locked in place by the gimbal locking nut To adjust the gimbal position loosen the locking nut and screw the gimbal up or down You will have to screw down the locking nut if you want to raise the gimbal up Always tighten the gimbal locking nut securely after adjusting the gimbal position Note that you can screw the gimbal down too far and not have enough thread engagement with the camera stage base To prevent this there is a visual cue on the gimbal stem that is a thread cutout It is OK to have the thread cutout just slightly visible as shown below If you go further and start to see the threads again you have dropped the gimbal too far and don t have recommended thread engagement in the base should have at least 3 full threads engaged The maximum extension for the gimbal stem is shown at left When you just begin to see the shiny thread cutout it means DON T GO ANY LOWER Blackbird User Manual Page 10 F Attaching the gimbal extender For cameras less than about 2 Ib you will need to use the gimbal extender which drops the gimbal down to allow correct vertical balance To install the gimbal extender
