Pan/Tilt for Caddx Tarsier

thingiverse

This is a work in progress of my pan/tilt mount for the Caddx Tarsier I want to use on the Sonicmodell Binary FPV plane. The design can still be improved, but that's not currently a priority. Feedback for improvement is highly appreciated! You'll need the following components: * Caddx Tarsier * Emax ES08MD-II (*absolutely necessary as no other servo will fit*) * PDI-9180MG (180° servo) * 7x3x3 mm ball bearing * Misc. screws (2*M2x16, 2*M2x12, 4*M2x6, (2*M2x3), 1*M3x6), 6*M2 washers and 1*M3 nut * 3x2mm bowden tube or similar to be used as spacers - but you could also 3D-print those * Small amount of CA glue Assembly: * Print the parts;) * Optional: install the PDI pan servo inside the Base using 2*M2x3 * Press the bearing into the Bearing_Bracket so that it aligns with the upper side (facing away from the build plate during the print). Glue the Bearing_Support to the other side (optional). * Mount the two brackets using the 2*M2x16 and 2*M2x12 screws. Cut bowden tube spacers or use a custom 3D print to be able to sandwich the electronics stack between the screws. Tighten the screws carefully (!) to avoid uneven pressure on the stack. I used four M2 washers between the metal cooling plate and the 3D printed parts. It's a bit fiddly to get the parts lined up, but once done, the whole thing is sturdy! See the second photo for details on where the parts need to go. * Install the tilt servo (Emax ES-08MG-II) * Dry-fit and then glue the servo horn provided with the Emax servo into the Pan_Tilt_Interface. Also, glue in the round servo horn provided with the PDI servo. Press the M3 nut in. * Screw the Pan_Tilt_Interface to the PDI pan servo using the supplied screw * Install the tilt assembly by pushing the Emax servo into the servo horn. * Screw the M3x6 screw through the nut into the bearing * Optional: Feed the wires from the tilt servo and the Caddx through the Base and secure them inside with a zip-tie as strain relief (attention: provide enough length of wires for the complete range of motion). You can also go without the "Base.stl". I designed it to rise the camera a bit over the canopy deck so you can get the plane a little more out of view and look down a bit more on the sides.
