So I smashed my 4" again, no blame to the frame as it took a lot of abuse.
While waiting for Karls new 4" frame to arrive for testing, a friend offered me a frame to get me in the air again (who also happens to be the designer).

I basically took all the guts and swapped the camera for a Caddx Ratel.
This frame has a deadcat layout and the build came in about 10g lighter as the frame is 3mm vs. the 4mm of the 40r.

Copy+Paste Pids for 3" from the betaflight wiki flew pretty well - gonna tune it some more but already pretty happy.
About 5 min. of freestyle on 850mah 4s. 159g dry weight.

I LOVE the caddx ratel cam - such a pleasure to fly.


  • I did use 3d printed tpu cam mounts to allow 25mm standoffs instead of the stock 30mm ones and the carbon side plates.
  • I also modded the axii mount for the 40r to be shorter and clear the props.

Flight footage

Skyzone DVR is cutting off a bit from the left in PAL so thats why the mount is only really visible on the right.

DJI has always owned the drone photography market, but smaller acrobatic drones are starting to enter the market. They have the advantage of close proximity flight indoors and around people. There's more artistic freedom and..

For the longest time we've been limited to 3 to 4 minutes of flight and lots and lots of batteries. With more efficient motors and frame designs it's now possible to push the envelope much further. This guide will walk you through the process of building a micro long range quad capable of flying 8-30 minutes and more than 4km. The build is moderately difficult, but with the right tools and steady hands..
