FrSky Horus addons - LRS, stand...

thingiverse

This is part two in a series about upgrading your FrSky Horus transmitter with a fixed handle (find the first one here: https://www.thingiverse.com/thing:3489731). Running high-power LRS from behind the transmitter, holding it vertically, or using pigtails for antenna can cause interference and damage to the internal components. I've taken my FrSky Horus outside and created a unified handle that makes it easy to dismount and attach the LRS to a retransmitter or switch between different systems. The best part is that the Horus design is naturally "back-heavy," so adding a lightweight LRS in front actually balances out the transmitter around the handle. To upgrade your FrSky Horus, you'll need: X10S_qlrs_mount.STL - a rotatable part that mounts the TX (I've also included an optional thicker version, X10S_qlrs_mount_v2, but it increases the total thickness by about 1mm). If you want to create a stand for your transmitter, print two "X10S_stand.STL" parts and attach them with a standoff. I've also included a JR module bay cover, remixed from https://www.thingiverse.com/thing:513861, which has space for angled pins. Internally, simply route the connector to straight 0.1" pins (common in most FC's) and secure them in place with some glue. Before gluing, attach the connector to the pins and push them deeper. I've tested this setup with crossfire, QLRS, and OLRS hawkeye, and it works flawlessly without any shielding on the TX required (try using OLRS@1W close to the JR bay - you'll still get a buzzing sound similar to the Taranis). If you're using QLRS, I've included two boxes: small (LED, button, and 1W module with heatsink) and bigger (http://forum.rcdesign.ru/f90/thread512643-75.html#post7894043 and https://www.rcgroups.com/forums/showpost.php?p=43832375&postcount=3589). To fit an Arduino in the box, you'll need to cut the sides down to the middle hole; the OLED module fits perfectly with a small piece of thick tape holding it in place. I've also included two photos of a protection case made from LDPE foam (packaging foam) that can be used as a makeshift protector. To make it, simply cut out the TX outline, create holes for the controlling components, heat and shrink the areas where you cut with a dremel, add some tape or glue, and it will become super-strong while being very light and compact. This protector takes up minimal additional space compared to the original box but provides better protection for your sticks and switches.
