This is compact box frame I designed a few years ago, it is build to carry a lightweight mirror-less camera

Design

At first, I'm not sure 4 motors can carry a mirrorless camera, but why not, lets just try it!
with motors inverted, the space for camera and battery is pretty big. this makes this frame to be 5 inch in size, but 7 inch in power~
this design introduce a lot of drag, so I'm expecting it to fly fast

Test Flight

Testflight with ation camera.

DummyWeight

Mounted with Dummy weight to simulate the Sony A7C, witch is 800g with the lens
This frame can carry Cameras that weight less than 1200g, just don't do any acro moves

Weight

Dry weight is:666g+
Total take-off weight is 1800g~2000g
The th flight time is about 6min

Hover Test:

With INAV ,Pos hold and RTH makes flying with expensive camera a little bit safer

The Pid for this quad is still not fine tunned, So the video from the camera is a bit shaky. A lot of tunning to be done~
