This is my next upgrade to my first quad. Because there were so many changes I decided to create a new profile build. This uses many of the same parts from my build at, but upgrades includes the T-Motor 722 Pro FC to take advantage of the DJI port, ExpressLRS and new Beaver Frame. In order to take advantage of the sbus, from this FC, I reversed the TX and RX ports for URART 5 in Betaflight CLI console. I also created a new wiring harness for the VTX, listed below, to connect to the DJI port. Everything else worked as expected. I created custom TPU part for the quad, and they are listed below. I'm deciding if a bumper is needed. I'll decide after it's maden flight. :-)

Hi, nice & clean build 👍
How did you attach the standoffs in the middle of the base plate? You had to remove the press nuts, right? Then the holes are bigger than the screw though, did you use some kind of washers to fill the gap?

optikool   Nov 17, 2022 

Yeah, I changed the screws and used an M3 screw at each end of the standoff. This is one of the customizations the frame can handle. I'll upload a couple more images of the underside of the fame.

But when you remove the press nuts, the diameter of the hole is much bigger than the holes for the other M3 screws. Does the standoff still fit and is not loose? Thanks for your attention. I’m looking forward to your reply.

No it is not loose at all. The arm core part is still there. The M3 screws screw into the standoff. I added a couple more pictures.

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..
