Pan Assy Mini FPV 180 deg.

thingiverse

A mini panning setup for the small 14x14 mm cameras. I used a Caddx Ant. You will need an Emax ES9251 servo and a piece 5x3 mm carbon fibre tube. It takes some fiddling to make the gears run smoothly and without binding against each other. I did a run-in using a hand drill and tooth paste to speed things up. Still there may be some position of the gears that runs best. Mark it with a pen. You will need to remove one of the mounting flanges on the servo, but not all! Leave a small part as a fixation against the base upper edge. Do not let the servo ride up in the base or the gears will interfere and bind. I used thin tape across the top of the servo, seems to work so far. You will need a 5 mm drill to ream the small gear and the camera holder to size. You will also need a 5.1 mm drill to ream the bore for the carbon fibre shaft. I used small drops of hot-glue to assemble the large gear and the servo 4-arm horn. As the function of the assy is very dependent on the precision of the printed parts, I'm including the F360 file should any modifications be needed. This design is probably not suited for contact with the ground, mine will be in the cockpit of a high-winger.
