Realacc X210 build (QAV-X clone)

I was looking for an X frame, and came across the Realacc X210 - which turned out is a QAV-X clone.. I really need to donate some cash to Lumenier!

I already had Emax 2205/2300 "red-bottom" motors and 30A ESCs (DYS XM30A) wired up to an Alien clone (Martian 1, a horrible thing) which was half built as the FC failed and I never went back to it - avoid the Skyline32 with OSD, basically the OSD switch to disable the UART didn't work... So you couldn't progress it, junk basically.

Anyway I grabbed these motors and ESCs off and put them on the X, after adjusting (extending) the ESC -> PDB wires (as I cut them super short for the Martian build), I got to this point (note the shorter now-desoldered wires to the right):

I used the built in PDB (which i'll talk about later) as below (5v and 12v wires soldered on here):

I had an SP F3 FC laying around, which I hadn't used one before but I quite like it so far. No OSD and not as neat as the BeeRotor, but it's what I had and it's highly rated by friends

FC placed on top (with wired buzzer) and a poor USB orientation I ended up changing later.

Next was the receiver. This is quite a tight build, and the Frsky X4R-SB just wouldn't fit in with the pins. So I desoldered them (like the XSR minus the mini-port), and ended up with this:

I used the Foxeer Arrow for the first time, which has a built-in voltage read-out OSD, single wire, nice and simple.. It's really all I need for racing, and meant I didn't need a fancy FC or additional OSD layer in this tight build

However I ended up getting really weird camera footage. Everything was fine on my 12v 3S test battery at home, but in the field using a 4S it looked like the world was melting. Ah, this is a bad cap or regulator experience I thought, of course! So I bypassed the 12v regulator on the PDB and wired it straight to the PDB. Yes there's some motor noise, but it's actually not bad.

Finished product, with 3D printed Xaomi Yi faceplate/holder:

Another shot of the finished product, with Joos batteries (my new favourite)

A good mate and 3D designer extraordinaire (!!) made up this VTX mount (top right), which is awesome. He's reiterating the design a bit to lower the height (you hit gates at times), and will refine it, but it's awesome and saves a lot of space on the build.

The VTX channel changer is nice and accessible:

Overall to date i've only flown LOS due to some config issues I had and the video issue, but i'll update this blog or others once I get it tuned in and running well. Hopefully this is my new favourite build
