533 Switchback Pro Cap / SMA Antenna Mount

thingiverse

Antenna and capacitor mount for the 533 Switchback Pro. Based on my other design for the Source V but specially sized for the Switchback Pro. This version keeps the antenna well away from the props. There are two files, one for the cap that ships with the Foxeer Mini Reaper 60A (10mm dia) and one for the old standby 1000uF (12.75 dia). This design has clearance for the battery pads of the Foxeer Reaper Mini 60A and the cap leads (watch polarity!!) are presented directly to the batt pads for soldering. I run the battery leads out one side of the frame, mount the ESC, then drop the cap holder in place followed by cutting and tack soldering the leads to the pads. It's easy to remove the cap for maintenance this way. Must be printed in TPU to get the SMA mount in place. To keep the size small the part is designed to flex while installing the SMA pigtail. Use needle nose pliers and a small screwdriver to wrangle it into position. Shining a flashlight into the translucent TPU helps to get the cap leads through the holes. I'm not a racer but I do like high performance quads for freestyle so having a way to mount a decent sized capacitor for noise reduction is a must. SMA allows me to quickly replace broken antennas. Added 6/21 : If a custom cap size is required, in Microsoft 3D Builder, create two 1mm radius 40mm length cylinders, roll 90 degrees, position x=12.5mm and x=7.5mm z=7.5mm. Create a cap cylinder of desired radius, 20mm long, position x=10mm z=7.5mm, merge with the 2mm cylinders, and drag it to snap to the end of the model. Follow with EDIT > SUBTRACT. I will be adding a 3mf model tonight with all the pieces required as well as a model with no cap holes for people wanting that.
