DumboRC FPV got an upgrade from the Turbowing. It wasn't a good signal. Swapped it out for a better one & better FPV distance. Rip around the field & no scraggle to dodge [ well not much ]
Much better to fly with the rates up but still needs a tune & sort out the camera mount to fix those oscillations.
Works really well on 4's, Much lighter than the 220 but I plan on making it lighter sometime.
