I have been perfecting my 2.5", 2s builds for some time now, and this is my latest and most progressed kwad, I am super-happy with the performance of - here I would like to share the details of the components used by me as well as some solutions (e.g. the RX, VTX and capacitor placement, the battery holding rubber band attaching to the frame, the filter and PID settings, of course etc).
This is one of my first builds where I used BF 4.3 and I am happy to report that the way the kwad flies, the locked-in feel, the handling of prop wash is far, far superior compared to BF 4.2.
