Troubleshooting a Quadcopter

I decided to cut ties with my Mudskipper frame, and move back to my zmr250 frame. I liked the way it flew better, and it was much lighter. I had purchased nicer components for the mudskipper build, so I wanted to migrate some of them back to the zmr. This is where my troubles begin.

I started by tearing down both of my quads. I purchased a new FPV camera, because my old Sony 1117 is definitely showing signs of wear. I went with the RunCam Owl Plus due its wide FOV and low light sensing. Plus it was orange!

I also wanted a new FPV transmitter, since I was thinking I might maintain 2 quads at some point, and wanted 2 full sets of FPV components. For this I went with the Foxeer FPV TM25 Transmitter, because it was completely adjustable in output power.

And last, but not least, I ordered a new receiver – since I had destroyed my 2nd FrSky X4R-SB during a crash. I decided to try the new FrSky XSB, because it was smaller, and only had one connector on it. The only downside I see to this receiver is the inability to *easily* replace antennas. With the X4R, I could snap on a new one, but these are soldered on.

So here is my latest instantiation of my ZMR 250. So far I’m digging flying 4S batteries. Much more power!
