My second Long range Chameleon Ti 7 inch, this time using DJI Air Unit. For some of the TPU parts in this build I needed to create and print custom parts to make everything fit, FC and ESC holder... Air Unit holder... and make everything easy to get too. I also needed to print a custom Antenna mount to also support a GPS unit. I also needed to extend the wire from the rear motors in order to reach the ESC.

It's awesome how each quad is different.

I've been looking to convert my 7" to DJI and this lines out what I want to do perfectly. Can you share the links for the printed parts? I see some of them, but not the ones for the antenna / GPS / AU. Cheers.

Thanks for the advice which I'm already aware of, but it sounds like you misread the post. He is having this issue without the screws touching the frame. I am NOT having this issue with the screws touching the frame. I also have grommets on the FC and ESC to reduce vibrations. I am very happy with the flight of this quadcopter and have not noticed any issues with the gyro.

Thanks for the info Optikool, I had been looking at your pics and asked to verify what i believed to be true, i.e. that you were using the top plate to help as well. I have my back end zip tied to the frame and it's soft mounted, so I'm going through my power system tonight. Could be a bad cap or a bad gyro.... still a great design...

All cool Every quad is different

Impressively neat build. :) It's encouraging to see that someone else has already done this, I'm looking to convert my analog chameleon 7". I've got a couple questions.

  1. Is the holder for the air unit necessary or do you think it would be possible to get by without it?
  2. How's your range with this set up? My concern is that the air unit antenna placement isn't optimal.

Thanks for the comment. The holder for the air unit is not necessary. I liked the design of the holder so I modified it to fit in this frame. But I'm sure you can use any holder that fits in the frame. I haven't taken this build out past half a mile, mainly because I haven't gone to an open area yet, but also because the DJI air unit doesn't currently support live audio, which I use. I generally use my other Chameleon 7" analog build for long range. :)

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..
