Ummagawd Remix w/ DJI FPV System

Ever since I got the DJI FPV System I have been converting over as many quads as I can. Because the DJI Air Unit is so big and bulky, not everything can accommodate it. Since I am a novice at building models for 3D printing, it took me a while to create a bottom tray that would fit the air unit. After a few failed attempts I finially got something usable and I could be found on Thingiverse. The direct link is listed in the “Parts List” below.

As I began my conversion, it occurred to me that Joshua Bardwell F4 AIO V1 Flight Controller only has one open UART port. I thought I could use a soft serial port to create another one, but it is not fast enough for the DJI OSD or Crossfire RX. So, now I need to replace the FC too. I dug around my stash of goodies and I end up picking the Matek F722 STD Flight Controller because it is also an AIO board.

Without a doubt I know that there will be lots of props in view with my FPV camera but I am happy to say the with a GoPro Hero 7 Black recording at 4K 60FPS there are NO props in my video.

Update (Apr 14, 2020)

The 3D printed bottom tray that house the DJI Air Unit was originally printed with PLA+, and that was my only may concern about this build. I was suggested to try Nylon, but I did not have any at the time. So, I end up buying some Nylon and Carbon Fiber Nylon. I wanted to try the CF Nylon first in hopes of the Carbon Fiber giving it a stiffer structure and the Nylon will flex on impact. I have never used these filaments but those are the expectation I was aiming for.

This is an excellent conversion. What did you print the bottom try in; nylon, ABS? And how is it flying? I love my SD Remix, maybe this should be its fate! :-)

Thanks, I just ordered some Nylon and Carbon Fiber Nylon to see if it feels. I am going to print one in PETG too... The Remix seem to fly the same after the conversion. Unfortunalty, I had to change the FC because the Joshua Bardwell v1 board did not support all the UART I needed. So the different FC and Firmware can make a difference.

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..
