I've added the TechFlex and Paracord to the build for reference.

Honestly, the sheathing on TOUGH-GRID paracord is much better and about 1/32" larger in diameter. Check it out and see if it would be an improvement, they have excellent ratings on Amazon so it looks good.

So, after some time - i've made some modifications / additions, along with other changes based on crash experience;

  1. antenna's were connected via a solid 3d print in ABS plastic. This turned out to be a bad move as the ABS is brittle enough that it snapped in a crash and chewed up my antenna's. Now, as you can see in the photo's - they've moved position and the tube holders are now made from flexible TPU. This stuff seems tough and I don't expect more issues.

  2. The motor protectors were again made from ABS, and lasted one crash. I've removed them for now.

  3. I moved the vtx underneath the top plate whilst ensuring I could still access the dip switches.

  4. I added an OpenLog and enabled blackbox in CleanFlight.

  5. I added a flexible TPU mount up top for a Xiaomi Yi.

All of the updated 3d parts came from

So the moral of the story: 3D printed parts don't last on 250's. I shrink tubed some zip-ties to my antennas to give them some rigidity. It's worked well so far!

Lovely build! Did you use shrink tubing to hold the paracord to the cables?

Big time.Its called chaffing.Leave the chaffing long enough it could cut wire.You will probaly have a short long before it physically cuts right through wire though.

I'll have to pay attention to that. I may have a wire or two that crosses the edges of my plates.

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..
