It printed nice with no infill and very little support, it really is great work & possibly the lightest frame in this 3D printed class! (trust me I've tried a few) I just wish there was a version for the 0603 or 0703 and even the 0802 they all have the same hole spacing it would only be one more frame to add to the lineup? If you did so it would make this masterpiece complete since there is evidence that those motors can swing a larger prop and get more efficiency. I'm thinking 0603 with 38mm props on 1s. My attempt to REMIX failed due to the file size of your STL. Tinkercad hates anything above 25mb and Sketchup is acting like a #%$@ today for some reason... I think my trial expired :-( here's one example of 0802 motors on 1S performing like a 2S setup https://www.youtube.com/watch?v=CgWXusnxVcI&t=31s Imagine a 0603 or 0703 motor with 38 mm propeller on 1S hmmmm.....
Test Fit Crazybee F3 was a Success
