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.

Mods

  • 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.

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
