I ordered some from the GearBest US warehouse during the last time there was a similar post , but they told me that they couldn ' t ship to me . I ' m in the US . <| sep |> Again , I apologize . But my career is solid , no midlife switches now . <| sep |> Try a servo or hook a scope up to it if you have one . Servo won ' t test sbus though but will test the rest of the receiver . Unplug everything and plug it back in to check connections and pins <| sep |> They ' re based in NI and the applications are now closed but maybe it will give you an idea of what ' s out there .

Apart from Corgi which I never tried , I ' m not a fan of the other engines you mentioned . I wish I could give you a detailed breakdown of why I stuck with unity instead of anything else I tried but all I can say is that Unity just felt right for me . Everything made sense and I love that whenever I ' m stuck , there ' s always someone with a plugin or even free code out there . As for pixel art , I work with gimp . I felt pyxel edit was too limited and photoshop is expensive . My only issue with it is that previewing animation is not optimalI basically just export a gif but I ' m sure there are plugins out there to make it easier . For tiling I use and then do some edits in gimp .
