The ImmersionRC 285 Vortex was my very first race quad that I flew FPV. Since most of the electronics is outdated and I had of lot of extra harware, I thought it would be fun to add some newer hardware to this quad. I am going to save the current FC and Blheli32 stuff for my other quads, so I thought I use some older F4 AIO and Blheli_S ESC here.

The Vortex is a heavy quad and without adding to much more weight, I thought I can lose a little first by removing all the electronics from the original PDB. I took a defective PDB board and removed the SMA connector, Caps, Chips, Connectors and etc. I was kind of suprised to see that all the stuff I removed weighed about 7 grams.

Next, I drill a 30.5x30.5 mount for the DYS F4 Pro Flight Controller. As first I was planning to use individual ESC, but I changed my mind and used a 4 in 1 instead. I was also debating if I wanted to stack the FC and ESC because I have a max space of 19mm to work with. Since I have all this extra space in the front of the quad, I put the FC there instead. Plus, the wires for the Immortal T and VTX was not long enough to reach past the ESC.

More coming soon....
