The Sky Surfer X8

The Sky Surfer X8 Figure 1: Sky Surfer X8 ready for take off I got into RC aviation in my mid‑20s. It was a lot of fun — but also filled with frustration and countless hours spent repairing airplanes I had crashed somewhere. About 30 years later, I decided to pick up the hobby again. This time I started with FPV drones. I bought a PNP version of a 3-inch drone (DarwinFPV Baby Ape II 4S). After some learning time, I decided to build my next drone from scratch, carefully selecting the parts and assembling everything myself (iFlight AOS 3v5). ...

EdgeTX Log Analyzer

My main motivation was to create an easy‑to‑use solution that allows me to quickly review recent flights. For example, I wanted to understand whether the reception quality of the two diversity antennas on my receiver differs, whether the antenna placement needs improvement, how high my throttle position was during flight, how much throttle was required to achieve a certain climb rate, how fast the RX battery voltage dropped, and much more. ...
