This 2.5" drone frame is named after the Clone Wars planet Raxus in honor of the QAV-Pro Micro drone from which it is derived. I wanted a more versatile frame with a VTX trunk that would securely (screwed down air units) accept many video systems including the DJI 03 Air Unit, Walksnail, HDZero, and analog.

The Raxis is an Open Source project and files are here: Thingiverse/6026097

There is also a build details here... Rotorbuilds/31175

It is a FAA Category 1 small unmanned aircraft that is permitted to operate over people are permitted subject to the following requirements:
-
Weigh 0.55 pounds or less, including everything that is on board or otherwise attached to the aircraft at the time of takeoff and throughout the duration of each operation.
-
Contain no exposed rotating parts that would cause lacerations.
-

-
The antenna mount, mounts to the bottom CF plate (the one without motor mounts).
-
Position the antenna backwards as shown and then rotate it into position. (pic #2)
-
Place the antenna in the mount as shown. Your antenna may be different. The antenna shown is the 40mm Osprey from FlyFishRC for the DJI 03 Air Unit. (pic #3)

-
Remove backing from Dual Lock (pic #1)
-
Position Dual Lock over FC screw holes and apply pressure to secure (pic #2)
-
Cut Dual lock into 3 long strips and secure to battery so there is a center channel missing. This will improve LIPO adhesion by avoiding contact with FC screws. NEW PICTURE NEEDED
-
Lastly hook 2 elastic bands thru the frame and back over the hook as shown (zoom in pic #3)

ERRATA...
-
Raxus frame going forward will not have dog bone cutout for 1mm CF camera mounts. CF mounts are inflexible compared to TPU camera mounts (pic #1)
-
This guide used a non production frame with a cut blemish (pic #2)
-
RX mount is not installed correctly... it should be rotated 180 degrees - new picture needed
-
Almost done!
