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.

How do you like the esc fc combo?

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.

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?

Did your Ori 4in1 come with a heatsink? If so, did you install it and how?

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!

This is the 3rd revision in the "Wizard Killer" series of builds based on the Martian II frame. The original Wizard Killer was my response to the successful Eachine Wizard RTF quad. The Mark III supersedes the more budget oriented Wizard Killer Mark II and is the most featured packed, simple to build and powerful of the three. The base weight with props is about 326g and fully loaded with a battery..

At last, the Topsky F7X V2 is available. This is the updated V2 release which came 3 months after the failed V1 model from October, 2017. V1 had several issues and most reviewers declared it an utter failure. Did Topsky fix the issues and are these worth buying? Let's find out. On paper this sounded like a wonderful new goggle. Unfortunately we were let down. The displays exhibited ghosting, the..
