Armattan Chameleon X4R-SB, TBS Unify Pro, LED and Beeper mounts

thingiverse

I was searching for a method to mount my FrSky X4R-SB RX and TBS Unify Pro HV (Race) VTX on my Armattan Chameleon frame without using any zipties, and after numerous revisions and redesigns (because of things like not testing the designs with props on and discovering that your antennas will be clipped straight away if you just point them upwards when coming out the back), they have evolved into this collection of parts that I am now utilizing on my build. * The **RX mount** is secured in place by the two posts of the aluminum rear part of the frame. The antenna of an X4R-SB can be passed through the mount out the back, where it has 3mm holes for antenna tubes. It also features a groove in the side wall, through which the cables for an LED strip can be routed to the LED bumper (see below). * The **VTX mount** sits on top of the RX mount and is locked in place with a bolt through the square hole next to the VTX antenna mounting hole. The **VTX Lock** is simply my term for a square washer to keep the VTX mount from sliding out, and it should work with any M3 bolt. Just ensure it is long enough to screw deep enough into the VTX mount, but not too long to protrude too far on the other end. I am also providing a rectangular **VTX antenna washer** that should be attached to the VTX antenna pigtail, so that it sits between the connector's tabs and the frame, to prevent the antenna from wiggling around. * The **LED bumper** was designed to allow an Adafruit Neopixel Stick to be attached to it, but it may work with other LED boards, like cheap Chinese clones. You will need two M2 bolts to attach the LED board, preferably something short like the ones provided with the frame. * The **beeper clip** gets clipped to the front of the frame, so that the beeper sits right behind the FPV camera, pointing downwards. You will be limited in what angles you can tilt your FPV camera, but it works reasonably fine with my Runcam Swift 2. The clip will fit a 12mm diameter beeper. There are cutouts in both the RX and VTX mounts to give you access to the respective board's buttons and onboard LEDs. If you are not using the Armattan PDB, which puts the XT60 connector on the side of the frame, you will need to route your battery lead out the front, e.g. between the stack and the camera cage (or any other way you see fit), as the holes in the back are used for fixing the mounts to the frame. Regarding the **TBS Unify Pro** versions, the HV and HV Race have the same dimensions and should both fit just fine, but the non-HV one (v2) is a bit smaller. It should still fit, but you will have to check if it isn't wiggling around too much. Important! You probably know this already if you have the Chameleon frame and tried fitting the stock Unify Pro pigtail connector into the hole in the rear, but for those who don't: You will need to grind/sand/cut off one of the tabs on the connector, otherwise you won't be able to screw the upper plate onto the standoff. This is not specific to my mounts, you will have to do that either way.
