Assembling and balance adjustment

Preparation

To assemble the Helm, first select the desired mounting mode, and work mode: 2 axis or 3 axis. There are a variety of scenarios for the 3-axis. Specific mounting equipment will be used for different scenarios. Such as hand-held, vehicle-mounted etc. Before assembling, mount the Helm on the mounting equipment. If you are using 2-axis Helm on Steadicam, you need to remove the panning axis motor and V mount battery mount on both sides of the Helm to reduce weight.

Attach the camera

Install the quick release plate to the bottom of the camera, two rods with a spacing of 60mm, and 15mm diameter are installed on the top of the camera. The distance between the rods and the optical axis of the lens is about 85mm.
Lens support brackets and other parts are needed for longer lens.

Balance adjustment
Assemble your system and Adjust the balance – In order to make the Helm play an excellent stabilization function, the Helm must be kept in a good balance before shooting. In its structure design, the engineers take into consideration of the symmetry of the system, which greatly facilitates its balance adjustment. When assembling the system with camera and other accessories, users should keep it in mind that it’s important to let the system remain its balance. In the assembly and balance adjustment, we should also note that although the ring-shaped structure of Helm allows greater freedom for the length of the camera and lens, but the excessively long camera and lens will increase the moving torque, which will also seriously affect the stabilizing performance of Helm. Always keep Helm in a balanced and more focused state as much as possible during the installation and adjustment.
In general, when installing the camera, the optical axis of the camera lens should also be at the center of the ring. Due to the difference in size of different cameras, it may be necessary to p r e p a r e c o r r e s p o n d i n g r i s e r blocks for different cameras. We have prepared corresponding riser blocks for popular cameras on the market. If necessary, you can contact us for purchase. Before balancing, install all other a c c e s s o r i e s n e e d e d f o r t h e camera, such as follow focus and mattebox etc., as well as any cables that need to be connected.

Adjust the balance of tilting axis – With the camera mounted, we need to adjust the balance of tilting axis. If the camera tilts downward, release the safety lock on the quick-release plate and move the quick-release plate backward until the camera is horizontally balanced. If the camera tilts upward, release the safety lock on the quick-release plate and move the quick- release plate forward until the camera is horizontally balanced.

Adjust the balance of rolling axis – After the tilting axis is balanced, we now start to adjust the balance of rolling axis, there are two steps: camera’s top/bottom balance and left/right balance adjustment.

Camera top/bottom adjustment
Keep the camera upright with the lens pointing straight up and make the side of the camera body parallel to the control panel and check if the ring is in horizontal position. If the camera tilts downward, add weight blocks to the top of the camera until the ring is horizontally balanced. If the camera tilts upward, add weight blocks to the bottom of the camera until the ring is horizontally balanced.

Checking left/right adjustment

Keep the camera upright with the lens pointing straight up and make the side of the camera body parallel to the control panel and check if the up-facing side of the ring is in horizontal position. The camera mounting plate can be adjusted slightly to adjust camera left/right balance. If the left side of camera tilts downward, adjust the camera mounting plate to the right or add appropriate weight to the right side of the camera. If the left side of the camera tilts upward, adjust the camera mount to the left or add appropriate weight to the left side of the camera.

Parameter setting

After balance adjustment, use the control panel to do set up Helm. Helm can also be controlled via external controller like the wheel controller. Power up Helm before starting setup.

Press the red knob to enter setup menu. Turn the knob to choose entry for setup.
When external controller like the wheel is used to do setup, first step is to enter the System to set wireless channel. Set both the channel on control panel and that on the wheel control at the same one. Connection is successful when the sign appears on the upper right corner of the screen.
Motor stiffness and strength can be set via Motor entry. Under Smoothtrack mode, motor speed, Deadband and sensitivity can be set.
. Under Remote entry, dead and, max speed and smoothing can be set. Data sources can also be set.
Under System entry, the following can be set: wireless, calibration and language.
