Finally got my speed controller back and have finish the cover case. I kinda quickly assemble them all together and have test run to see if new design has better performance. I am glad it works much better after I reduce the size and sacrifice a lot of parts. (I still like the large size design but it's hell too heavy for the motors I used.)
After I got my controller done I will post detail on robot section. Just wanna prevent updating the old ■■■■ again and again on homepage.
