This is my first 4" build, and my first build that's clean enough to not be emarassing! I went with the Omnibus Nano/Ori ESC combo to reduce the wiring required in such a tight space, and I'm glad I did. It was a quick and easy build. The X6B is the largest component in the whole stack. I still need to figure out a permanent solution to keep the antenna out of the props, but zip ties work for now. This thing is fast, smooth (really smooth), and you have to love the whistle T1's make.

Hey man, i got the same Fc although i decided to go with the 32bit Ori esc. plan to use 4s. did you have issues powering the FC? every time i plug in the lipo, the FC becomes laggy and i cant arm.. any tricks to powering the FC with a 4s?
Nice build! It's awesome to see so many crabs popping up!
Are you having any motor heat issues with those DAL T4040 bullnose? I've used DAL T4045 and TJ4045, and they get hot, but not too hot. I can imagine the bullnose being a bit too much.
My solution for dipoles recently is to remove the heatshrink, attach a small ziptie, to the frame, cut the ziptie so the end of it is about halfway down the metal part of the dipole, insert it into the metal part of the dipole, and add fresh heatsink.
I do something similar with RX antennas, generally hanging them off the front arms and using zipties and heatshrink to secure them to the frame.
Also, DEFINITELY ziptie that XT60 pigtail to the standoffs, or you're likely to rip the pads straight off in a big crash! And I'd go for lighter gauge wire, look at your packs, they're probably 14AWG or so, 12 is a bit much!
Guides & Reviews
This guide will walk you through the process of building your first FPV quad. The goal with this design was to build a low-cost, lightweight quad, yet powerful enough to safely carry a GoPro in close proximity areas. I chose these parts to minimize the amount of soldering at no cost to the quality. A typical build requires around 30 solders while this only needs 25. It's not a huge difference, but..

In late 2019 DJI made inroads into the FPV scene with their remarkable low-latency digital system. It gave us a 720p video feed with latency on-par with the status quo, analog video. Traditionally we've used analog video systems for low-latency video, but the video quality is far from ideal. It's a trade-off we've been willing to accept for the control. Now we've got the best of both worlds and what..

How do you like the esc fc combo?
It's really nice. The cable to plug the two together made it so simple, and it saved me from soldering 9 wires (and finding somewhere to stuff them). The FC has everything you want too (OSD, current sensor, etc.). I'd happily use this combo again in the future.
Thanks! How's the video noise? Did you use a capacitor, and how many amps does it pull on a full throttle punch out? I was thinking of using it on an ultralight with 22205 motors and am a little hesitant.
Sweeeeeeeet build! I don't really buy that this has a current sensor though. RTFQ is notorious for putting up incorrect information. There's no shunt resistor, right. Everything in this field that measures current has a shunt resistor. What am I missing? Even the ad for their colony esc states a "built in current sensor" and the pin out says "NC". If you turn on "current sensor" it will read all sorts of gibberish - did you calibrate it?
I have the same fc/esc combo and I can't get any sort of current sensing working.
