QUICK START GUIDE
15. Fine tune the spring tension using the Pitch (FIGURE 1 - #6) and Roll (FIGURE 1 - #7) axes
adjustment holes on the upper plate.
REPLACING THE AXIS CAMS
1. Disconnect the base USB cable from the PC.
2. Remove the base from the VPC Desk Mount or other mounting method.
3. Remove the attached grip from the base.
4. Loosen the spring loading tension on the Pitch and Roll axes via the adjustment holes on the
upper plate.
5. Remove the 4 x M4 screws from the lower plate (FIGURE 1 - #13). Store the lower plate in a
safe location to avoid damage.
6. Remove the 4 x M4 screws from the upper plate (FIGURE 1 - #1).
7. Remove the 4 x M5 screws affixing the U-Bracket to base exterior and gimbal structure.
8. Remove 2 x M3 screws on the front side of the base, affixing the VPC-Controller board to the
interior of the base housing. NOTE: Pay attention to the spacers used for mounting the
VPC-Controller board.
9. Carefully lift the gimbal and electronics from out of the base housing, being sure not to
damage the electronics or wiring.
10. Completely loosen the spring loading screw for the axis you wish to replace the spring on.
While you do this, hold the cylindrical nut from the lower side of the base.
11. When the spring loading screw is removed from the cylindrical nut, open the lever axis arm
(FIGURE 2 - #2 #6) to access the cam.
12. Remove the 2 x M3 cam mounting screws (FIGURE 2 - #10).
13. Remove the existing cam (FIGURE 2 - #5, #11) from the gimbal and replace with your desired
cam. NOTE: Removing the cams for the first few times can require additional effort,
especially the pitch cam. To help remove the pitch cam (FIGURE 2 - #5) you can rock the cam
side to side to ease it out of the cam slot.
14. With the new cam installed, complete the reassembly of the base by following the steps
back in reverse from step 15.
